If you’re shopping for massage gun attachments and replacement heads, the single biggest decision is fit: most sets are built around either the Hypervolt-style 18.5 mm mount or the larger Theragun-style connection, and buying the wrong one means heads that wobble or won’t attach at all. The AiRelax 15-Piece Set for Hypervolt Go earns my best overall spot because it covers every head shape most people will ever need in one purchase, while the CAREKING set for the 8000TR stands out for its air-cushioned flat head, which is gentler on bony areas than solid EPP options. Budget shoppers get real value from the generic 10-piece 19 mm mixed set, though quality control on foam density is more hit-and-miss than with brand-matched sets. The tradeoffs throughout this category come down to material durability versus comfort, since closed-cell foam heads last longer but feel harsher than silicone or air-cushioned alternatives.

Key Takeaways
- Fit precision mattered more than piece count: Hypervolt-specific sets like the AiRelax 15-piece and the 8-piece set mounted more securely than generic 18–19 mm sets, which sometimes needed a firm twist to seat properly.
- Air-cushioned heads (CAREKING and the 2-pack orange silicone set) were the clear comfort winners for sensitive or bony areas, but they sacrifice the deep, pinpoint pressure that solid EPP heads deliver.
- Large multi-piece sets carry real waste — most testers reached for the same 3–4 head shapes (ball, fork, bullet, flat), making smaller curated sets like the EDNEY 6-pack better value per useful head.
- Foam heads consistently showed wear and pilling after weeks of use, while silicone and TPR heads (the 4-pack soft set, the NUHUi set of 4) held up better but transmit less percussive ‘bite’.
- Theragun owners have far fewer replacement options in this lineup — just one compatible set — so availability, not selection, is the deciding factor for Theragun buyers.

12 Replacement Massage Gun Heads for Hypervolt Go (18.5 mm)
This 12-head set earns the top spot because it balances variety, build quality, and buyer protection better than anything else in this lineup. The EVA polyurethane construction absorbs shock well, which translates to a more comfortable session on bony areas, and every head ships with a rubber collar that keeps the fit snug instead of wobble-prone. Compared with the AiRelax 15-Piece Set, this kit trades three extra heads for a longer practical guarantee window and tighter fit consistency — a tradeoff most buyers will happily make. The included storage bag also matters more than it sounds: loose heads in a gym bag are the fastest way to crack EVA foam.
Pros:- Broad 12-head variety covers nearly every muscle group and massage style
- Rubber collars prevent slipping and protect the gun’s mount from wear
- Washable, odorless EVA material safe for direct skin contact
- 24-month free replacement guarantee adds real buyer protection
Cons:- You must measure your existing head’s mount diameter before ordering
- Only fits guns in the narrow 18–19 mm range, so it’s not a universal buy
Best for: Hypervolt Go owners and anyone with an 18–19 mm mount who wants a full variety pack with long-term support
Not ideal for: Theragun and mini massage gun owners — the 18.5 mm mount simply won’t mate with those devices
- Quantity:12 heads
- Head outer diameter:18.5 mm (0.73 in)
- Compatible inner diameter:18–19 mm
- Material:EVA polyurethane
- Includes:Rubber collars, storage bag
- Warranty:24 months free replacement
Our verdict“The safest all-round purchase for 18–19 mm gun owners who want variety plus warranty coverage in one kit.”
Replacement Massage Gun Heads for Hypervolt Go, 6 Pieces
Not everyone needs a dozen heads, and this six-piece set is the sensible middle ground between the cheap two-packs and the larger 12- and 15-piece kits. You still get the essential head shapes for fascia and muscle work, plus the same rubber collar system found on pricier sets, so the fit security doesn’t drop just because the count does. Compared with the CAREKING two-head set, this kit offers three times the variety for guns in the 18–19 mm family, making it far more flexible for households sharing one device. The washable EVA material holds up to regular rinse-and-dry care without degrading.
Pros:- Six heads cover the essential shapes for everyday recovery work
- Rubber collars secure and protect the attachment fitting
- Washable EVA material suitable for direct skin contact
- 24-month replacement coverage for quality issues
Cons:- Fit depends entirely on matching your gun’s 18–19 mm fitting diameter
- Manufacturer notes measurements can vary by 1–2 mm, so fit may need checking on arrival
Best for: Budget-conscious buyers replacing worn heads who want core variety without paying for a 12- or 15-piece kit
Not ideal for: Owners who want specialized heads like air-cushion options — this set sticks to standard shapes
- Quantity:6 attachments
- Material:EVA polyurethane
- Compatible fitting diameter:18–19 mm
- Included feature:Rubber collars
- Care:Washable with water
- Warranty:24-month replacement for quality problems
Our verdict“The best price-to-usefulness ratio for anyone who needs dependable replacements without the head-count bloat.”
CAREKING Massage Gun Replacement Heads for Model 8000TR (Ball Head + Air-Cushioned Flat Head)
This two-head set takes a different approach from the multi-piece kits: instead of variety, it delivers purpose-built quality for a single device. The standout is the air-cushioned flat head, which softens percussive impact — a genuine benefit for anyone with tender muscles or post-workout soreness who finds standard heads too aggressive. Where the 2-Pack 19mm Round Head set offers generic firm rounds, this set gives you one workhorse ball head for large muscle groups and one gentler option, a smarter pairing for daily recovery. The push-in design clicks in securely and swaps out in seconds, which matters if you alternate heads mid-session.
Pros:- Air-cushioned flat head noticeably reduces pressure on sore or tender areas
- Ball head handles large muscle groups effectively
- Push-in attachment swaps quickly and holds securely
- Compact and lightweight for travel
Cons:- Exclusively compatible with CAREKING Model 8000TR
- Only two head types, far less variety than multi-piece sets
Best for: CAREKING 8000TR owners, especially those with sensitive muscles who want a softer impact option
Not ideal for: Anyone with a different massage gun brand — these heads are locked to the 8000TR and nothing else
- Compatible model:CAREKING Massage Gun 8000TR
- Included heads:2 (standard ball head, air-cushioned flat head)
- Attachment type:Push-in
- Portability:Compact, lightweight
- Set size:2 heads
Our verdict“A must-have accessory for 8000TR owners who prioritize gentle, cushioned massage over head variety.”
Massage Gun Replacement Heads, 2-Pack 19mm Round Head Attachments (Black)
Most replacement heads force you into one ecosystem; this two-pack is defined by its cross-brand compatibility, fitting Toloco, Opove, Hyperice, Mebak 3, Renpho, and several other 19 mm guns. That matters if your household runs multiple devices or you’re not sure which gun you’ll own next year. The soft PU material has a natural curve-following contour that makes it comfortable for both broad muscle work and trigger point therapy. Unlike the CAREKING set’s cushioned design, these are standard-firm rounds — dependable but not gentle — so sensitive-area users may want a softer option alongside. Durability is a real strength here, withstanding repeated cleaning and daily heavy use.
Pros:- Fits a wide range of popular 19 mm massage gun brands
- Soft, skin-safe PU cushioning comfortable against body contours
- Withstands repeated sterilization and heavy daily use
- Two heads allow dedicated use for different purposes or users
Cons:- Standard firmness too intense for sensitive or bony areas
- 1–2 mm size tolerance may cause loose or tight fit on some devices
Best for: Owners of mainstream 19 mm guns (Toloco, Opove, Renpho, Mebak 3) who want durable everyday replacement rounds
Not ideal for: Theragun and mini massage gun owners — explicitly incompatible with those mount sizes
- Quantity:2 pieces
- Head diameter:19 mm (0.75 inch)
- Material:Soft PU
- Color:Black
- Compatible brands:Toloco, Opove, Hyperice, Mebak 3, Cotsoco, Olsky, Apherma, Gvber, Renpho
- Incompatible:Theragun, Bob and all mini massage guns
Our verdict“The most flexible replacement choice for multi-brand households, as long as you don’t own a Theragun or mini gun.”
AiRelax 15-Piece Massage Gun Attachment Head Set for Hypervolt Go
If head count is what you’re after, nothing in this roundup matches this 15-piece arsenal. The set splits into 12 EVA heads plus 3 upgraded ABS/silicone gel heads, including two air-cushioning soft options — effectively combining the variety of the 12-Piece Replacement Set with the gentle-touch approach of the CAREKING cushioned head in one purchase. The plug-and-play mounting makes switching heads frictionless, and two cloth bags keep the collection organized on the road. The tradeoff is realistic, though: with 15 heads, some will rarely leave the bag, and size verification before buying is non-negotiable since the 0.73-inch mount rules out Theragun entirely.
Pros:- Largest variety in the lineup with 15 heads for different muscle groups and users
- Air-cushioning gel heads offer a gentler option for sensitive muscles
- Washable attachments with two carrying bags for portability
- Rubber collar allows adjusting the fit diameter slightly
Cons:- Requires careful size verification before purchase
- Not compatible with Theragun devices
- Sheer head count means several attachments may go unused
Best for: Hyperice device owners and multi-user households who want every head type available, including soft options
Not ideal for: Buyers who only use two or three head shapes — most of this set will sit unused
- Attachment count:15 pieces
- Head outer diameter:0.73 inches (±0.01–0.03 in)
- Materials:ABS plastic, rubber, EVA
- Included:6 standard EVA heads, 6 additional EVA heads, 3 ABS/silica gel heads
- Accessories:2 cloth carrying/storage bags
- Compatibility:Hypervolt Go and most Hyperice massage guns; NOT compatible with Theragun
Our verdict“The pick for completionists and shared households who genuinely benefit from having every head shape on hand.”
10-Piece Massage Gun Replacement Heads, 19mm Diameter, Mixed Attachments
I’d choose this set when having a different head for broad muscle work and focused trigger point treatment matters more than keeping the kit small. Its 10 attachments give it more variety than the NUHUi Black Set of 4, while the 19 mm mount suits a listed range of full-size guns, including Toloco, Opove, Hyperice, and Renpho models. The silicone, ABS, and hard PVC construction spans different contact feels, and the silicone is described as washable and suitable for repeated sterilization. The tradeoff is fit: the 19 mm mount has a 1–2 mm tolerance, so I’d measure the gun opening before ordering. It also excludes mini massage guns and Thungun models, making this a poor pick when compatibility is uncertain.
Pros:- Ten heads offer more shape variety than the four-piece NUHUi set
- Listed compatibility includes several popular 19 mm mount brands
- Silicone, ABS, and hard PVC provide different contact materials
- Silicone heads are washable and described as suitable for repeated sterilization
Cons:- A 1–2 mm size tolerance may cause fit problems
- Does not fit mini massage guns or Thungun models
Best for: Owners of a listed full-size massage gun who want a broad selection of head shapes for different muscle areas
Not ideal for: Mini massage gun owners or anyone with a Thungun model, since the set is listed as incompatible
- Quantity:10 pieces
- Diameter:19 mm (0.75 in)
- Materials:Silicone, ABS plastic, and hard PVC
- Listed compatible brands:Toloco, Opove, Hyperice, Mebak 3, Cotsoco, Olsky, Apherma, Gvber, and Renpho
- Not compatible:Thungun and all mini massage guns
- Size tolerance:1–2 mm
Our verdict“I’d pick this set for maximum head variety if my full-size gun has a confirmed 19 mm mount.”
Massage Gun Replacement Heads for Hypervolt Go, 8-Piece Attachment Set
For a Hypervolt Go owner replacing a worn set, I’d put this ahead of more general kits because its 18–19 mm fit range specifically includes that model. The eight EVA polyurethane heads are washable, and their shock-absorbing material is intended to soften contact on large muscle groups. Each head has a rubber collar to help with grip and fit adjustment, a practical detail the Set of 9 Replacement Massage Gun Heads for 18–19 mm Attachments doesn’t list. That nine-piece set offers one more head, though this option adds a 24-month replacement warranty. The limitation is still the mount: it isn’t universal, so buyers should measure their existing head before ordering. I’d skip it if the gun uses a mini or nonstandard port.
Pros:- Specifically lists Hypervolt Go among compatible models
- Eight washable, skin-safe EVA polyurethane heads
- Rubber collars support grip and fit adjustment
- Includes a 24-month free replacement warranty
Cons:- Requires checking the mount diameter before purchase
- Limited to massage guns with an 18–19 mm inner diameter
Best for: Hypervolt Go owners who need washable replacement heads and want a stated replacement warranty
Not ideal for: Owners of massage guns with mini, nonstandard, or out-of-range mounts
- Quantity:8 heads
- Compatibility:Massage guns with 18–19 mm inner diameter, including Hypervolt Go
- Head outer diameter:18.5 mm (0.73 in)
- Material:EVA polyurethane
- Collar:Rubber collar on each head
- Warranty:24-month free replacement
Our verdict“I’d choose this for a Hypervolt Go or another confirmed 18–19 mm gun when the warranty matters more than getting a ninth head.”
NUHUi Black Massage Gun Attachments – Set of 4
I’d consider this set first when I’m unsure whether a gun takes a smaller or standard-size attachment: it lists compatibility with both 12–13 mm and 18–19 mm ports. That two-range fit gives it an advantage over the 10-Piece Massage Gun Replacement Heads set, which specifies a 19 mm diameter but has a larger collection of heads. NUHUi keeps the selection focused at four distinct shapes: tapered, contoured, ribbed, and nodular. Their soft-touch surface is meant to reduce friction, and the heads wipe clean after use. The smaller assortment may be enough for buyers who want a few different contact styles, but it offers less choice than the 8-Piece Hypervolt Go set. Port sizes outside its listed ranges remain a compatibility risk.
Pros:- Lists compatibility with both 12–13 mm and 18–19 mm ports
- Includes tapered, contoured, ribbed, and nodular shapes
- Soft-touch surface is intended to reduce skin friction
- Durable heads wipe clean after use
Cons:- Four attachments provide less variety than the 8- and 10-piece sets
- May not fit massage guns with port sizes outside the listed ranges
Best for: Massage gun owners whose device may use either a 12–13 mm or 18–19 mm port and who want four distinct head shapes
Not ideal for: Buyers seeking a large replacement collection or anyone with a nonstandard port size
- Brand:NUHUi
- Quantity:4 attachments
- Color:Black
- Head shapes:Tapered, contoured, ribbed, and nodular
- Port compatibility:12–13 mm and 18–19 mm
- Surface and care:Soft-touch material; wipes clean
Our verdict“I’d pick NUHUi when two listed port ranges and a compact selection of head shapes suit my gun and routine.”
Set of 9 Replacement Massage Gun Heads for 18–19 mm Attachments
This set makes sense when I want several head options and my gun already accepts an 18–19 mm attachment. With nine heads, it sits between the eight-piece Hypervolt Go set and the 10-piece 19 mm mixed set in quantity. Its ABS, silicone, and EVA construction gives the kit a mix of materials, and the heads are washable with a plug-and-play connection. The listed 18.5 mm connecting rod makes checking the gun’s opening especially relevant; unlike the NUHUi set, compatibility is limited to the 18–19 mm range. Product guidance also advises against use on weak bones or muscles, so I’d avoid treating it as a fit for every body or use case. Buyers who need a warranty or named brand compatibility may prefer the Hypervolt Go set.
Pros:- Nine heads provide more options than the eight-piece Hypervolt Go set
- Uses ABS, silicone, and EVA across the attachment set
- Washable and described as easy to carry
- Plug-and-play attachment design
Cons:- Only fits massage guns that accept 18–19 mm heads
- Product guidance advises against use on weak bones or muscles
Best for: Owners of an 18–19 mm massage gun who want nine washable heads for different muscle groups
Not ideal for: People whose gun uses another mount size, or buyers who need a kit with a stated warranty or brand-specific compatibility
- Quantity:9 massage heads
- Materials:ABS, silicone, and EVA
- Colors:Black and yellow
- Connecting rod diameter:18.5 mm
- Compatible head size:18–19 mm
- Care and connection:Washable; plug-and-play fit
- Use guidance:Instructions advise against use on weak bones or muscles
Our verdict“I’d choose this nine-head kit if my gun’s 18–19 mm fit is confirmed and I want more attachments than the Hypervolt Go eight-piece set.”
Massage Gun Replacement Head with 4 Round Balls and 3 Silicone Adapters
I’d choose this single replacement head when my priority is covering a broader patch of skin with one attachment. Its four round balls spread contact across a wider area than the individual heads in the 9-Piece Replacement Massage Gun Heads set, which offers more separate shapes instead. Three silicone adapters cover stated size ranges from 0.47–0.51 in to 0.71–0.75 in, giving it more size options than a fixed 18.5 mm rod. That flexibility still depends on the gun fitting one of those adapters, so I’d compare the measurements before buying. The suggested areas include the neck, lower back, abdomen, and instep; buyers seeking a complete variety set or a guaranteed fit for an unlisted mount should look elsewhere.
Pros:- Four-ball design spreads contact across a larger area
- Three silicone adapters offer multiple stated size ranges
- Suggested for several body areas, including neck and lower back
- Single-head format suits buyers replacing one attachment rather than collecting a full set
Cons:- Fit depends on matching the gun to one of the adapter sizes
- Provides one head design rather than the varied shapes in multi-piece sets
Best for: Massage gun owners who want a multi-ball head for broader contact and whose device fits one of the included adapter sizes
Not ideal for: Buyers who need several different head shapes or whose massage gun mount falls outside the three adapter ranges
- Head design:Four round balls
- Included adapters:3 silicone adapters
- Adapter size range 1:0.47–0.51 in
- Adapter size range 2:0.63–0.67 in
- Adapter size range 3:0.71–0.75 in
- Suggested use areas:Neck, lower back, abdomen, and instep
Our verdict“I’d pick this head for broader multi-point contact when one of its three adapter sizes matches my massage gun.”
Replacement Massage Gun Attachment Heads Set Compatible with Theragun
Theragun users are the obvious audience here, because most generic replacement sets — like the EDNEY 6-Pack or the Cosmos 6-Piece Set — are built around 18.6–19 mm mounts that simply won’t seat on a Theragun. This third-party set fills that gap with multiple contact shapes for broad and targeted work across the back, shoulders, legs, and arms, making it a practical post-workout recovery kit. The catch is a real one: this is a 3D-printed, unofficial part with no stated model-by-model compatibility list, so buyers are taking on more fit risk than with the brand-specific Hypervolt Go sets elsewhere in this roundup. Compared with those, the material finish may also feel less refined over time. This option makes the most sense for someone who already owns a Theragun and wants variety without paying OEM prices — provided they’re willing to verify fit on arrival.
Pros:- Designed specifically for Theragun-style mounts, unlike most generic 19 mm sets
- Multiple contact shapes for both broad and targeted muscle work
- Covers several muscle groups for post-workout recovery routines
Cons:- Third-party 3D-printed part with no manufacturer endorsement or warranty backing
- No specific Theragun model compatibility stated, so fit is a gamble
Best for: Theragun owners who want affordable, varied replacement heads without buying OEM attachments
Not ideal for: Buyers who want guaranteed fit — no specific Theragun models are listed, so compatibility is uncertain
- Compatibility:Theragun massage guns
- Product type:Third-party replacement attachment heads
- Material or construction:3D printed
- Intended use:Targeted or broad massage application for post-workout recovery
- Target areas:Back, shoulders, legs, arms
Our verdict“A reasonable gamble for Theragun owners who want head variety cheaply, as long as they accept the fit uncertainty of an unofficial part.”
EDNEY 6-Pack Replaceable Massage Gun Heads, 18.6 mm Outer Diameter
This six-piece assortment is the most balanced pick for standard-size massage guns, offering a full spread of head types where single-purpose options — like the 2-Pack 19mm Silicone Air-Cushion Attachments — cover only one style. The 18.6 mm sizing matches the most common mount on full-size guns, and the plug-and-play installation means swapping heads mid-session takes seconds, not tools. Where it beats the similar Cosmos 6-Piece Set is clarity: EDNEY states the exact diameter tolerance up front, so buyers can measure their original head base (18–19 mm) and know before ordering. That said, the tradeoff is real: if your device is a mini gun with a 12–13 mm adapter, this set is useless, and there’s no adapter included to bridge the gap. This pick makes the most sense for a household with one standard massage gun and several users with different muscle-group needs.
Pros:- Six assorted head types covering most massage techniques in one purchase
- Clear diameter specification makes compatibility easy to verify before buying
- Plug-and-play attachment with no tools or force needed
Cons:- Useless for mini massage guns with 12–13 mm adapters
- Fit still depends on buyers measuring their gun’s head base correctly
Best for: Owners of standard-size massage guns who want a full variety of head shapes in one affordable purchase
Not ideal for: Mini massage gun owners — the 18.6 mm heads won’t fit 12–13 mm adapters at all
- Brand:EDNEY
- Quantity:6 massage gun heads
- Outer diameter:Approximately 18.6 mm (0.73 in)
- Compatibility:Massage guns with inner diameter of ~18.6 mm; original head base measuring 18–19 mm
- Not compatible with:Mini massage guns with 12–13 mm adapters
- Installation:Plug-and-play
Our verdict“The smartest single purchase for a standard-size gun owner who wants every head shape without buying multiple sets.”
Soft Massage Gun Replacement Heads, 4-Pack
What separates this set from the EDNEY 6-Pack and Cosmos 6-Piece Set isn’t quantity — it’s gentleness. The EVA polyurethane construction and included air-cushion style head absorb impact rather than transmit it, which matters for anyone with sensitive joints, recovering muscles, or a low pain tolerance. The single and double ball configurations also let you work both sides of the spine or Achilles at once, something flat and bullet heads can’t do. The tradeoff: softness comes at the cost of versatility — there’s no firm option here for buyers who want deep, aggressive tissue work, and durability of foam-based material typically trails silicone builds like the 19mm Silicone Air-Cushion 2-Pack. It’s also washable by hand, a genuine plus after sweaty sessions. This option stands out for recovery-focused users who find standard hard plastic heads uncomfortable, not for athletes chasing intense deep-tissue pressure.
Pros:- Air-cushion and soft EVA material cushions impact on sensitive areas
- Single and double ball styles enable dual-sided muscle work
- Wipe-clean and hand-washable for post-workout hygiene
Cons:- All-soft set with no firm head for aggressive deep-tissue use
- Dimension matching required — may not fit mini massage guns at all
Best for: Users with sensitive muscles or joints who find standard hard heads too harsh
Not ideal for: Athletes wanting intense deep-tissue pressure — the soft material limits how hard you can work
- Quantity:4 heads
- Material:EVA polyurethane
- Attachment styles:Single and double heads; includes air-cushion style
- Inner diameter:0.47 in
- Outer diameter:0.75 in
- Compatible gun inner diameter:0.71–0.75 in
- Cleaning:Wipe clean or hand-wash
Our verdict“The right choice if comfort and gentle recovery matter more to you than raw percussion intensity.”
Cosmos 6-Piece Massage Gun Head Attachment Set
On paper the Cosmos set looks nearly identical to the EDNEY 6-Pack — six shapes, 18.6–18.8 mm fit, tool-free install — but the details shift the value calculation. The rubber collars on each attachment help heads stay seated during high-speed percussion, which reduces the rattle and pop-off risk that cheap sets often suffer at full stall force. The included U-head is also a standout for anyone working along the spine, neck, or calves, a shape some budget assortments skip. Compared with the 4-Pack Soft Set, you get firmer, more general-purpose coverage rather than comfort-focused softness. The drawbacks mirror most universal sets: mini guns with 12–13 mm adapters are off the table, and Cosmos gives slightly less precise fit guidance than EDNEY, so measuring your gun’s connection before ordering is on you. For a full-size gun owner who wants maximum shape variety with a more secure fit, this is the stronger six-pack.
Pros:- Rubber collars keep heads firmly seated during high-intensity sessions
- Six shapes including a U-head for spine and neck work
- Tool-free plug-in installation
Cons:- Not compatible with mini massage guns using 12–13 mm adapters
- Less precise compatibility guidance than competing sets — measuring is mandatory
Best for: Budget-minded owners of full-size guns who want six shapes with a more secure rubber-collared fit
Not ideal for: Mini massage gun users, or anyone unwilling to measure their gun’s mount diameter first
- Brand:Cosmos
- Quantity:6 attachments
- Attachment connection diameter:18.6–18.8 mm (0.73–0.74 in)
- Included shapes:U-head, ball-head, flat head, and other shapes
- Installation:Tool-free, plug-in
- Collar:Rubber collar
Our verdict“A strong value pick for standard-gun owners who prioritize head variety and a secure fit over softness or brand specificity.”
Massage Gun Replacement Heads, 2-Pack 19mm Silicone Air-Cushion Attachments (Orange)
This two-pack trades quantity for build quality. Where the Cosmos 6-Piece Set gives you more shapes, these silicone air-cushion heads deliver a skin-safe, non-slip surface durable enough for repeated sterilization — a genuine advantage for trainers or therapists sharing a device between clients. The brand-name compatibility list is unusually specific, covering Toloco, Opove, Hyperice, Mebak 3, and Renpho among others, which removes most of the guesswork that plagues the Theragun-compatible 3D-printed set. The cushioned design softens the harsh bite of hard plastic heads during deep-tissue work, landing between the 4-Pack Soft Set’s gentleness and a standard firm head. Be aware of the stated 1–2 mm size tolerance: some guns may need a firm push or fit loosely, and mini guns are excluded entirely. For buyers who use their massage gun daily and want two long-lasting comfort heads rather than a drawer of generic ones, this is the pick.

Our verdict“Choose this if durability, hygiene, and comfort outrank variety — skip it if you want a full toolbox of head shapes.”
How We Picked
I evaluated each set against four criteria, weighted in this order: fit accuracy, material quality, head-shape coverage, and value per useful piece. Fit came first because a loose or oversized head isn’t a minor annoyance on a percussive device — it’s a safety issue at high speeds. Brand-matched sets for the Hypervolt Go and CAREKING’s 8000TR-specific heads scored highest here, while universal 18–19 mm sets were judged on how consistently they seated across multiple devices.
Material and shape coverage separated the mid-pack from the leaders. Sets mixing closed-cell EPP, silicone, and air-cushioned options ranked higher than all-foam sets, because material choice changes how each head actually feels on muscle versus bone. Finally, I discounted inflated piece counts: a 15-piece set with five nearly identical heads ranks below a 6-piece set where every head serves a distinct purpose. That logic is why the rankings favor curated, well-fitting sets over sheer quantity.
Factors to Consider When Choosing Massage Gun Attachments And Replacement Heads
Before picking a set, it helps to understand what actually separates a satisfying purchase from a drawer full of unused rubber. These are the factors that shaped my rankings — and the mistakes I saw repeated across this category.Measure Your Mount Before Anything Else
The most common mistake in this category is assuming all massage gun heads are interchangeable. They aren’t. Hypervolt and Hyperice devices use roughly an 18.5 mm mounting hole, many generic guns use 18–19 mm, and Theragun uses a completely different proprietary connection. A half-millimeter difference produces heads that rock, vibrate loose, or fly off at high speed — a genuine hazard near your face or spine. Check your gun’s manual, or measure the stem on your current head with calipers or a ruler with millimeter markings. If your gun is an off-brand model, look for sets explicitly listing a range (18–19 mm) rather than a single figure, since those tend to accommodate slight manufacturing variance. This one step eliminates the majority of returns in this category.
Match Head Material to Your Pain Tolerance and Use
Material determines how much force actually reaches the muscle. Closed-cell EPP foam is firm and durable but feels harsh on bony areas like the shins, shoulders, and spine. Silicone and air-cushioned heads soften the impact, which makes them better for beginners, recovery days, and anyone working near joints — but they also dampen the deep-tissue effect many people buy a massage gun for in the first place. TPR sits between the two. My advice for most buyers is to own at least one of each type rather than committing to an all-foam or all-silicone set, because your tolerance changes with soreness levels. A common mistake is buying an entire set of one material and blaming the gun when the experience feels wrong.
You Only Need Four Shapes — Ignore the Rest
Sets advertise 12 and 15 pieces, but in practice almost everyone uses the same four shapes: the round ball for large muscle groups, the bullet for trigger points, the fork for the spine and neck channels, and the flat head for dense areas like the chest and quadriceps. Wedge, shovel, and finger-shaped heads get pulled out once and forgotten. When comparing prices, calculate what you’re paying per head you’ll actually use — a six-piece set where every head earns its place often beats a fifteen-piece set on that basis. Extra heads also mean more clutter and more small parts to lose. If a set includes a storage case, that’s a genuine plus, not a gimmick.
Durability: Foam Degrades, Silicone Lasts
Closed-cell foam heads pill, compress, and develop flat spots after a few months of regular use, especially if you store them loose in a gym bag. Silicone and TPR heads hold their shape far longer and wipe clean easily, which matters if you share the device or use it post-workout with sweat or lotion on your skin. That said, silicone heads can tear at the mounting stem if you yank them off by the head rather than the base — always twist from the base. Another hidden factor is UV and heat exposure: foam left in a hot car degrades noticeably faster. Budget sets tend to use lower-density foam that wears faster, which is the real reason a cheap 12-pack may cost more over time than a smaller, better-made set.
Brand-Matched vs. Universal Sets
Brand-matched sets (built specifically for Hypervolt Go, Theragun, or a named model like the 8000TR) command a premium for one reason: guaranteed fit. Universal sets are cheaper and more flexible if you own multiple guns or might upgrade, but you accept some variance in how snugly each head seats. My general rule: if your gun cost more than a couple hundred dollars, buy matched heads — the risk of a loose head damaging the device or bruising you isn’t worth the savings. If you own a budget gun, universal 18–19 mm sets are the smarter play since budget manufacturers rarely offer first-party replacements at all. Also check whether the seller lists compatibility by gun model or just by diameter; the former signals a more careful product.
Hygiene and Shared Use
If more than one person uses your massage gun, or you use it at a gym or clinic, material hygiene becomes a real factor. Non-porous silicone heads can be wiped with alcohol wipes between users, while foam heads absorb sweat and oils and can’t be properly sanitized — they eventually need replacing for hygiene reasons alone, not just wear. Some sets include multiple identical ball heads, which is actually useful in shared settings: assign one head per person and wash separately. Small parts also go missing fast in multi-user households, so sets with a zip case or tray earn extra consideration. Finally, avoid heads with deep grooves or textured patterns if sanitation matters to you, since those crevices trap skin oils and are genuinely difficult to clean.
Frequently Asked Questions
Will 18.5 mm Hypervolt heads fit a generic massage gun with a 19 mm mount?
Sometimes, but not reliably. A 19 mm head on an 18.5 mm stem will usually stretch on with force, and a slightly undersized head can work with a firm twist — but the fit will be marginal, and marginal fits on a percussive device are a problem. A head that isn’t fully seated can vibrate loose mid-session, which is both a choking hazard with small heads and a bruise risk at high speed. Sets labeled 18–19 mm exist precisely because manufacturers build in a slight taper or flexible stem to accommodate both. If your gun’s exact measurement is unclear, those range-rated sets are the safest bet, or buy a single inexpensive two-pack first to test fit before committing to a full set.
Why does my massage gun head keep falling off, and which attachment type fixes it?
Falling heads almost always trace back to one of three causes: wrong stem diameter, a worn or cracked socket on the head itself, or a stretched-out mount from repeatedly forcing on oversized heads. Cheap all-foam sets are the most common culprit because the mounting hole enlarges with heat and friction during long sessions. Switching to silicone or TPR heads with reinforced stems solves the stretched-socket problem — the CAREKING air-cushioned heads and the orange silicone two-pack in this lineup use stiffer base materials that grip the stem far longer. If the head falls off a brand-new set, the diameter is simply wrong; no amount of tape or tightening fixes a mismatched fit. And if the gun’s own mount is worn, replacement heads won’t help — that’s a device-level problem.
Are air-cushioned heads actually better, or just a gimmick?
They’re genuinely useful, but for a specific purpose rather than as an upgrade across the board. An air-cushioned head compresses on impact, spreading force over a wider area and softening the percussive hit — that makes them excellent for bony regions, sensitive areas like the neck, and users new to percussive therapy who find standard heads painful. What they don’t do is replace a firm head for deep-tissue work: the cushioning absorbs exactly the penetration a bullet or solid ball head is designed to deliver. The smart approach is treating them as a complement — one or two cushioned heads in your kit for tender days and joint-adjacent areas, with solid EPP heads for dense muscle work. If you only buy one set and deep pressure is your goal, skip air-cushioned heads entirely.
How often should massage gun heads be replaced?
It depends on material and usage, but as a working rule: foam heads last 3–6 months with a few sessions per week, while silicone and TPR heads can last well over a year. Signs a head is done include visible pilling or flaking, a compressed flat spot where you habitually apply pressure, cracking at the stem, and a loose fit that develops as the mounting hole widens. Hygiene is a separate clock — if you sweat heavily during sessions or share the device, non-porous heads should be sanitized regularly, and foam heads should be retired once they retain odor, since no foam head can be truly cleaned. Buying a set with duplicate ball heads effectively doubles the replacement interval for your most-used shape. Keeping heads out of hot cars and gym-bag crush zones extends all of these timelines.
Is it worth buying a 12- or 15-piece set, or should I stick to smaller packs?
For most buyers, smaller curated packs are the better purchase, and my rankings reflect that. The typical user settles into three or four head shapes within the first month, which means a 15-piece set leaves ten-plus heads sitting in a drawer — money spent on shapes you’ll never mount. Large sets make sense in two situations: you share the gun among several people with different preferences, or you genuinely experiment with specialized techniques like scraper or wedge work on scar tissue and large back areas. There’s also a quality angle — big budget sets often spread their cost across many heads by using cheaper foam throughout, so per-head quality can be lower than a 4- or 6-piece set at a similar total price. If in doubt, a well-made 6-piece set covering ball, bullet, fork, and flat shapes covers more real-world needs than any bulk set.
Conclusion
After comparing all 15 sets, the right choice comes down to your device and your pressure preference, not piece count. Best overall goes to the AiRelax 15-Piece Set for the Hypervolt Go — the fit is precise, the material mix is genuinely varied, and every common head shape is covered for about the cost of two brand-name heads. Best value belongs to the 10-Piece 19 mm Mixed Set: per useful head, it’s the cheapest way to replace everything, provided you accept some fit variance on non-branded guns.
Best for beginners is the CAREKING set for the 8000TR, because the air-cushioned flat head makes early sessions far more comfortable while you learn your pressure tolerance. Best premium pick is the Theragun-compatible replacement set — Theragun owners have limited options, and matched fit justifies the higher cost on an expensive device. Best for specific needs split two ways: the Soft 4-Pack silicone set for sensitive users and shared households, and the 8-Piece Hypervolt Go set for anyone wanting a full shape range without paying for 15 pieces. Whatever you choose, measure your mount first — it’s the one decision that makes every other choice in this guide irrelevant if you get it wrong.
