Replacement heads are where most massage guns quietly stop being useful. You buy a gun, you get two or three tips, and then you find out the one shape that would actually reach your shoulder blade is not included. The fix is a head set that matches your gun’s slot and gives you the shapes your body keeps asking for — or, if you are starting from nothing, a full gun that already ships with a deep assortment of them.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The single thing that decides whether a head set works is the diameter of the mounting slot at the bottom of your existing head — measure it first, then read massage gun attachments for adults with that number in hand.

How To Choose The Best Massage Gun Attachments for Adults
A massage gun attachment is a small plastic or foam head that screws or slots onto the end of a percussion gun and decides where the vibration lands. A bullet tip reaches a knot under the shoulder blade; a round ball covers the flat of the back. A flat disc on the same spot just rattles the surface without getting under it. Before you look at head counts or colour options, settle three things: what your gun’s socket measures, what material touches your skin, and how often you actually use the gun.
Measure the socket before anything else
Almost every compatibility failure traces back to one number — the outer diameter of the round base that pushes into the gun. A head set measuring about 18.5 mm (0.73 inches) at that base is built for guns with an inner diameter in the same range, and a 1-2 mm difference is normal because these are measured by hand. Grab a ruler and check the head that came with your gun. If its base sits between 18 and 19 mm, a set built to that measurement will drop straight in.
EVA foam versus hard ABS plastic
EVA is a dense, slightly springy polyurethane foam that absorbs the shock of the piston before it reaches bone, so it feels softer on a hip or a shin. ABS plastic heads are rigid, and the rigid ones are usually the pointed or Y-shaped tips meant for narrow areas between muscle groups. Silica gel caps sit between the two — they are the squishy, rounded ones aimed at tender spots. Skin-safe, washable EVA is the material most sets lead with, and it can be rinsed under the tap after a sweaty session.
How many heads is enough
You can cover a whole body with about four shapes: a round ball for large muscles, a flat disc for the back, a bullet tip for trigger points, and a fork or U-shape for the spine or calf. Sets that run to eight, fifteen, or twenty heads add air-cushion domes, scrapers, and arch shapes on top of those basics. The extra heads beyond four are mostly duplicates and scrapers, so they pay off only when several people share the gun. If a partner or family shares the gun, a bigger set earns its place because each person can keep their own tip.

Detailed Reviews
1. Massage Gun Heads for Hypervolt Go, 8 Replaceable
Our pick — 4.0+★ from 250+ verified ratings; the strongest balance of quality and price.
Eight heads that turn a two-tip gun into a full-body tool, as long as your socket measures right.
The number that decides everything here is 18.5 mm — roughly 0.73 inches — which is the outer diameter of each head’s mounting base. Your gun needs an inner socket in that same range, and a 1-2 mm variance is tolerated because these bases are measured by hand. Check the base of the head your gun came with; if it lands between 18 and 19 mm, these push straight into the slot with no sanding and no adapters.
The material is EVA polyurethane, a springy shock-absorbing foam that softens the piston’s hit before it reaches bone. That makes these the right pick for a hip, a thigh, or the meat of a shoulder rather than a hard poke. They are odourless, fine against bare skin, and you can rinse them under running water after a session. Each one also carries a rubber collar that grips the socket and can be used to fine-tune how snug the fit feels.
Compatibility is what wins buyers over, and it is the thing the review pages dwell on longest — the 8-head spread earns its keep on the shapes, not the count. As buyers put it: “Six attachments better than the four from the manufacturer.” The set covers a wide range of needs, including a scraper shape that owners describe as giving fast relief on a sore elbow. What the heads do not do is tell you which shape is which — the packaging carries no label explaining what each attachment is for, so you will be matching shapes to muscles by trial.
What You Are Actually Buying
- Eight EVA polyurethane heads that rinse clean under the tap
- Rubber collars grip the socket and let you adjust how tight the fit sits
- Plug-and-play install with no polishing or modification needed
- A wide shape spread that covers large muscle groups and fascia work
Where It Falls Short
- No printed guide on the packaging telling you which head does what
- One shape in the set has arrived without its soft outer piece, which makes it uncomfortable to press in
- Only a fit if your gun’s socket lands in the 18-19 mm window
Reach For These If: You already own a compatible gun and want more shapes without buying another machine.
Measure First: Anything outside an 18-19 mm socket will not seat properly, so check before ordering.
2. AiRelax Massage Gun Attachments for Hypervolt Go, 15 PCS
Fifteen heads in one bundle, and the two squishy cushion domes are the reason to pick it.
Fifteen attachments is the largest head-only bundle here, and the make-up is deliberate: 6 popular EVA heads, 6 more EVA heads for different areas, and 3 upgraded ABS and silica gel heads. The two air-cushioning soft domes are the standouts — they are the ones you press against a tender spot that a hard ball makes you flinch away from. All fifteen share the same 0.73-inch base, with a 0.01-0.03 inch tolerance on manual measurement.
Materials split three ways: ABS plastic, rubber, and EVA. The rubber collars adjust the diameter of the fit so a slightly loose socket still holds. It all arrives with two cloth bags, and both the bags and the heads can be washed with water — handy when one person uses the dome on a calf and the next wants it on a neck. Note the fit boundary: this set does not work with Theragun 3, and it is built for most Hyperice guns.
Fit is the honest sticking point, and it is the most-discussed subject in the reviews for good reason. Some of the softer plastic balls have split after roughly a year of sitting unused, and the screw-in style of a RENPHO gun will not accept these at all without sanding the ends down. Where it does seat, quality is what people talk about most — the moulding feels solid and the variety is wider than the heads that came in the box. Worth knowing before you commit: most of the set is good, but not all of it is great, and a handful of the tips are finished roughly at the edges.
The Cushioned Edge: The two air-cushion soft heads are the genuine differentiator here — rounded and gentle enough for sensitive muscles, and a real step softer than the firm EVA domes most sets ship with.
The Fit Caveat: This is a Hyperice-shaped set. Screw-in guns and Theragun 3 owners are simply not the audience, and no amount of force changes that.
Your Set If: Several people share one gun and someone in the house needs the softest possible contact.
Not Your Set If: Your gun uses screw-in heads rather than a push-in socket.
3. AERLANG Massage Gun Deep Tissue 6 Head Muscle Massager
A whole gun with six heads and four rhythm modes, for anyone who has not bought one yet.
If there is no gun in the house to attach anything to, this is the entry point — and the spec that does the work is the motor’s 1400-3200 rpm range across 9 speed levels and 4 massage modes. The four modes give you different percussion rhythms so a sore calf and a stiff neck do not get the same treatment. The six included heads cover an expanded percussion range, each one shaped for a different muscle group.
Physically it is the heaviest thing on this list at 2.91 pounds in its 11.77 x 7.6 x 5.39 inch package, and it carries a handle for moving it around the house. That bulk is the trade for a full gun rather than a bag of tips. It runs on one included 12V battery, and the quiet motor is built to be used at home, in the office, or on the go without announcing itself.
Build quality is what wins people over — the pressure feels strong on every one of the 9 settings, and the 4 modes change the rhythm rather than just relabelling the same pulse. Where it stumbles is endurance. Longevity past a handful of sessions is the other open question, and a few units have stopped holding a charge far sooner than anyone would like.
Reasons It Earns a Place
- 4 massage modes plus 9 speed levels across a 1400-3200 rpm motor
- Six heads included, so you are not shopping for shapes on day one
- Quiet motor and a carrying handle for moving between rooms
- Strong, noticeable pressure even on the lower settings
What You Give Up
- No battery-level indicator anywhere on the unit
- Runtime falls well short of an hour on a charge
- At 2.91 pounds it is the heaviest pick here
- Durability over months rather than weeks is unproven
Pick It For: A first gun at a friendly tier, especially as a gift for someone who has never owned one.
Think Twice For: Long sessions — the battery will not carry you through an hour without a top-up.
4. cotsoco Massage Gun Deep Tissue
Twenty speed steps and nine heads — the widest adjustment range of any gun here.
Twenty speed levels is the headline, and the top of that range reaches 3200 rpm on a 12V battery. Between the lowest step and that ceiling you get a genuinely fine-grained dial, so you can find a setting between “barely touching” and “too much” instead of jumping over it. Nine massage heads cover legs, arms, back, and neck, and the whole thing ships in a carrying case with a user manual.
It weighs 2.78 pounds, a touch lighter than the AERLANG gun above it, and the shape is designed to sit in a palm. A type-c charging cable means you can top it up from the same lead as your phone. The quiet-motor claim is aimed at shared spaces — the airport, a hotel lobby, an open-plan office — and owners back that up, describing it as running quietly even while pressing hard into a knot.
The motor is this gun’s best argument. It holds 3200 rpm under pressure without shutting off or overheating, and it comes out the other side of months of daily use still working, which is a harder claim than raw power. Deep tissue is where it earns its keep; the grip fits a hand cleanly and the pressure stays steady rather than fading as you lean in. The smaller caveat is the heads themselves — they are a bit smaller and less punchy than the numbers imply, and one of them has arrived with a sharp moulding ridge, so check each tip before the first session.
Why It Leads the Field: A 3200 rpm motor that does not flinch under load, plus 20 speed steps to land exactly where you want — that combination is what makes this the gun to beat for daily recovery work.
Handle It Properly: The USB-C charging is convenient, but the last stretch of a charge runs hot near the port, so keep an eye on it during the final fill and use a current-limited adapter rather than a fast PD brick.
The Strong Buy For: Anyone who wants a proven, quiet, high-head-count gun for post-training recovery and shared spaces.
Go Elsewhere If: You expect every included head to feel as substantial as the motor.
5. cotsoco 20-Head Massage Gun Set
Twenty heads and a one-button control scheme, built for a household rather than one person.
Twenty specialized heads is the most you can get in a single box here, and the control system is built to match a shared gun. One button handles power and mode switching, dedicated plus and minus keys step through the 9 intensity levels, and a built-in LED screen shows you the battery level and current setting at a glance. The 9 modes split into P1-P3 for gentle relaxation, P4-P6 for graduated tension release, and P7-P9 for a high-frequency pulse meant for deep tissue recovery.
A 10-minute auto shut-off protects the motor from overuse, which matters when several people are passing the gun around. It weighs 2.64 pounds, the lightest of the three full guns here, and charges over Type-C with a 5V/2A adapter. Build quality is the aspect that wins people over most — a high-torque motor delivering strong, consistent percussion that owners describe as getting deep into the muscle fibres. For self-use on a back, the family-friendly design and the display make it easy to operate without help from anyone else.
Two things to plan around. Runtime is short of what heavy users want; a couple of ten-minute sessions on the lowest intensity is roughly what you get, and a household of users means someone is always reaching for the charger. It is also a chunkier body than its weight suggests, and a slender hand will notice the size. One owner found a single ball head pop off after someone leaned against it, though it clicked straight back on — treat the tips gently and they stay put.
Why Twenty Heads Matters: With 9 modes and 9 intensities alongside them, everyone in the house can find a shape and a rhythm that suits them without negotiating over one favourite tip.
The Trade-Off: That much adjustability runs the battery down quickly, so plan your sessions around the 10-minute auto shut-off rather than expecting a full hour.
The Family Pick: Buy it when the gun will be shared and the widest choice of heads and intensity steps actually gets used.
The Catch: Bulk and short runtime per charge make it less appealing as a pure travel gun.
Know the Specs
Socket Diameter and Head Fit
The base of a massage head is the round stem that slides into the gun. Its outer diameter has to match the gun’s inner socket, which is why most replacement sets quote a figure like 0.73 inches. A 1-2 mm gap is normal in either direction because the parts are measured by hand, and a rubber collar can take up a little slack. If your gun’s head base sits well outside that window — or uses threaded screw-in heads rather than a push-in slot — a set like this simply will not seat, and no amount of pressure fixes it.
Percussion Speed and Intensity Levels
Speed is quoted in strokes or revolutions per minute — rpm — and the range here spans from about 1400 up to 3200 rpm across different guns. More speed steps means a finer dial between gentle and firm, which helps if you want light work on a neck and firmer work on a thigh from the same device. Intensity levels are a separate control on some models and change how hard the motor drives at a given speed. Higher speed is not automatically better; on a shin or shoulder blade, the setting you can tolerate sits near the bottom of the range.

The Bottom Line
For most people already holding a gun, the Massage Gun Heads for Hypervolt Go 8-Pack is the one to order — an 18.5 mm base, eight washable EVA heads, and a plug-and-play fit that has won over a steady stream of gun owners. If you are shopping for a household rather than one person, the cotsoco 20-head set spreads twenty shapes and nine intensity steps across a family, provided everyone is fine with short sessions between charges. And where daily recovery volume matters most, the cotsoco percussion massager holds its 3200 rpm under load without overheating — a hard thing to beat at this tier. One practical note before you click: measure your gun’s socket first, because a head set that does not seat is a head set you will not use.
