Quick Answer
The ball or standard head handles 80% of what most people need: large muscle groups like quads, glutes, and hamstrings. Use the flat head for dense muscle and bone-adjacent areas, the bullet or cone for pinpoint trigger points and feet, the fork around the spine and Achilles, and the soft dampener or cushion for sensitive, tender, or bony spots. The rest are situational. You do not need all of them to get the benefit.

Most massage guns ship with a tray of four to six interchangeable heads, and most people use exactly one of them, usually whichever was already attached out of the box. That is a waste of the tool. The attachment changes how the percussion actually feels and where it is safe to use, far more than the speed setting does.
The short version: the round ball or standard head does most of the work, the soft dampener handles anything tender, and the bullet handles knots. Everything else is situational. Below is what each head is actually for, organized by the muscle groups and jobs they suit, so you can stop guessing and pick the right one. The shapes and names come straight from how Therabody and Hyperice (the two brands whose naming everyone else copies) document their own attachments. There is one thing to know if you are shopping for heads rather than a gun. Hyperice's applicator set for the Hypervolt 1 and 2 line lists a fork, ball, cushion, flat and bullet, while its Hypervolt 3 set lists a fork, cushion, flat and wedge.

Quick Reference: Which Attachment for Which Job
Taking each head's job from the brand that makes it:
- Ball / Standard. Therabody names both large and small muscle groups, and Hyperice names quads, lats and pecs.
- Large Ball. Low-impact treatment of large muscle groups: glutes, hamstrings and quads.
- Flat. A larger area on a denser muscle group: hamstrings, glutes, back and chest.
- Bullet / Cone. Trigger points, hands, feet, and small or hard-to-reach muscles.
- Fork / U-shape. Paraspinals, upper traps, forearms, ankle and calves, avoiding the Achilles tendon.
- Dampener / Cushion. Stubborn knots, tender spots, beginners and the neck.
- Supersoft. Particularly sore muscles, and elbows, knees and joints.
- Thumb. Trigger points and the lower back.
- Wedge. Shoulder blades and IT bands, for "scraping" and "flushing" motions.
Why the Shape Matters More Than the Speed
Every massage gun head delivers the same stroke. The motor and amplitude don't change when you swap attachments. What changes is how that force meets your body, and it comes down to one thing: contact area.
A small contact area concentrates all the force into a single point, so the same motor feels intense and digs deep. That's a bullet head on a knot. A large contact area spreads the same force across more tissue, so it feels softer and covers more ground. That's a large ball on a hamstring. The material matters too. A firm head transmits more of the percussion into the muscle, while a soft foam head absorbs some of it before it reaches you.
So the practical rule is: bigger and softer for comfort and coverage, smaller and firmer for depth and precision. Match that to the area you're treating. A broad, healthy muscle like the quad can take a firm ball. A tender spot near a bone wants a soft, wide head on a low speed. Getting this right is the difference between a massage gun that helps and one that leaves you bruised.
The Attachments, One by One
Ball / Standard Head: Your Default
This is the head you'll reach for most. The rounded surface gives enough contact area to be comfortable on big muscles while still delivering real depth. It suits quads, hamstrings, glutes, calves, and the lats, essentially any large, healthy muscle group. Therabody sells it in two sizes, the Standard Ball and the bigger Large Ball; Hyperice calls its equivalent the round head and pitches it for quads, lats, and pecs.
If you only learn one attachment, learn this one. For general post-workout use and the kind of recovery routine covered in our home recovery setup guide, the ball head covers the overwhelming majority of what you need.
Best for: Quads, hamstrings, glutes, calves, lats, general use.
Large Ball: Wide, Low-Impact Coverage
A bigger sphere spreads the force across even more surface, dropping the intensity and making it ideal for covering large areas quickly. Therabody recommends the large ball specifically for the low-impact treatment of big muscle groups like glutes, hamstrings, and quads. It's the comfortable option when you want a gentler, broad sweep rather than targeted depth.
Best for: Glutes, hamstrings, quads. Large-area, lower-intensity work.
Flat Head: Dense Muscle and Bone-Adjacent Areas
The flat head trades the ball's rounded dig for an even, controllable surface. That makes it the dense-muscle head. Hyperice says the flat attachment "generally works best to cover a larger area on a denser muscle group such as hamstrings or glutes", and its own massage-gun guide calls it "great for your back or chest when you want to cover more area quickly". It feels firmer and more even than the soft heads without the concentrated bite of the bullet.
Best for: Hamstrings and glutes, with the back and chest named in Hyperice's own guide.
Bullet / Cone: Pinpoint Precision
The smallest contact area of any attachment, the bullet (Hyperice) and cone (Therabody) concentrate the full force of the motor into a single point. That's what you want for trigger points, stubborn knots, the small muscles of the hands and feet, and tight spots that a broad head just glides over. Hyperice notes it's also useful for localized work within a larger muscle, like the subscapularis.
The catch is intensity. Because the pressure is so concentrated, a few seconds is enough. Sustained grinding on one spot is how people bruise themselves. Use it briefly and keep checking in with the sensation.
Best for: Trigger points, knots, hands, feet, small muscles.
Fork / U-Shaped Head: Around the Spine and Achilles
The fork's two prongs straddle a bone or tendon so you can treat the muscle on either side without striking the bone itself. Hyperice recommends it for the paraspinal muscles either side of the spine, the upper traps, the forearms, and the calf and ankle area, explicitly without making contact with the Achilles tendon. The gap in the middle is the whole point: muscle gets the percussion, bone passes through untouched.
This is a slow, careful head. Never let the prongs drift onto the spine, and never drive it directly into a tendon.
Best for: Either side of the spine, upper traps, forearms, around the Achilles.
Dampener / Cushion: Tender and Sensitive Areas
When something is sore, bony, or sensitive, the soft heads come out. Therabody points its dampener at stubborn knots and tender areas, calling it a gentle, yet firm low-impact treatment. Hyperice's cushion is the softest head in its set, aimed at beginners and sensitive spots like the neck. Both do the same job: take the edge off the percussion so you can treat areas a firm ball would punish.
Best for: Tender muscles, bony areas, beginners, sensitive spots.
Supersoft: For Particularly Sore Muscles
Therabody's Supersoft head goes a step beyond the dampener, described by the brand as ultra-gentle for particularly sore muscles or areas that need a lighter touch. If a muscle is genuinely inflamed or you're easing back after a hard session, this is the head that lets you use the gun at all without overdoing it.
Best for: Very sore muscles, the most sensitive areas.
Thumb: Mimicking Hands-On Pressure
Shaped to imitate a human thumb, this head is built for the kind of pressure a massage therapist applies with their thumb: trigger-point work and the muscles of the lower back. It gives a firmer, more targeted feel than the ball without the pinpoint sharpness of the bullet.
Best for: Lower back, trigger-point therapy.
Wedge: Scraping Strokes
The angled wedge is Therabody's attachment for the shoulder blades and the IT band, marketed for "scraping" strokes drawn along the muscle rather than pressed into one spot. It's the most situational head in the tray, useful if you specifically work the IT band or shoulder blades, easy to ignore otherwise. Therabody's own words are that it is "perfect for 'scraping' and 'flushing' motions, it mimics similar deep tissue techniques to improve mobility and circulation". Mobility and comfort are the honest reasons to reach for it.
Best for: Shoulder blades, IT band, scraping-style strokes.
How to Choose — and What You Actually Need
Start with two or three heads, not all of them
The marketing rewards guns with the most attachments, but the number in the box is close to meaningless. Almost everyone's real-world kit is three heads: the ball or standard for general use, a soft dampener or cushion for anything tender, and a bullet or cone for knots. Add the fork if you work around your spine or Achilles, and the wedge if you have IT-band issues. The rest mostly stay in the drawer.
Firm material digs deeper, soft material protects
Beyond shape, the material changes the feel. Hard plastic or metal heads transmit the full percussion and are best on healthy, sturdy muscle. Closed-cell foam and rubber heads absorb some of the force, which is what makes them right for sensitive areas. When in doubt on a new area, go softer and slower first. You can always step up.
Check fit before buying replacement or universal heads
Each brand publishes compatibility against its own named devices. Hyperice's applicator set for the Hypervolt 1 and 2 line says "not compatible with Hypervolt 3 line", and its Hypervolt 3 set says "Compatible with the Hypervolt 3 line only". Therabody prints a device list on each head: "Compatible with PRO, Elite, Prime, Sense, Relief, Mini, G3PRO, G3 (sold separately)". Third-party "universal" sets exist, but fit and security vary, and a head that wobbles or pops off mid-use is worse than useless. Buy from your gun's own manufacturer and check it names your model. If you're still choosing a gun, our best percussion massagers roundup and the Theragun vs Hypervolt comparison cover which heads each model includes.
Safety doesn't change with the head
No attachment makes it safe to use a massage gun on the spine, the front or sides of the neck, the throat, joints, pulse points, or any area of acute injury, swelling, or numbness. The head changes how the muscle work feels; it doesn't change the no-go zones. Research on percussive therapy suggests benefits for short-term range of motion and perceived soreness, but those benefits come from sensible use on muscle, not from chasing intensity.
Frequently Asked Questions
Which massage gun attachment should I use?
For most people most of the time, the round ball or standard head. It suits large muscle groups like quads, hamstrings, glutes, and calves. Switch to the flat head for dense muscle near bone, the bullet or cone for pinpoint trigger points and the feet, the fork for muscles either side of the spine or Achilles, and the soft dampener or cushion for tender or bony areas. Match the head to the size and sensitivity of the area.
What is the flat massage gun head for?
A firm, even-surface head best on dense muscle. Hyperice names hamstrings and glutes for it, and its own guide names the back and chest. It spreads force more evenly than a ball and is more controllable over flatter areas, with a firmer feel than the cushion but without the pinpoint intensity of the bullet.
What is the fork (U-shaped) attachment for?
It works either side of a bone or tendon without striking it. Hyperice positions it for the muscles either side of the spine, the upper traps, forearms, and around the calf and Achilles. The central gap lets the prongs hit muscle while the bone or tendon passes through. Use it slowly and never on the spine itself.
What is the bullet or cone head used for?
The smallest contact area of any head, concentrating all the force into one point, ideal for trigger points, knots, hands, feet, and small or hard-to-reach muscles. Because the pressure is so concentrated, use it briefly and lightly.
Do I need all the massage gun attachments?
No. Most people get the full benefit from two or three: the ball or standard for general use, a soft dampener or cushion for sensitive areas, and a bullet or cone for trigger points. When buying a gun, whether it includes those core shapes matters far more than the total head count.
Are massage gun attachments universal across brands?
Not reliably. Each brand publishes compatibility against its own named devices. Hyperice's Hypervolt 1 and 2 applicator set says "not compatible with Hypervolt 3 line", and its Hypervolt 3 set says "Compatible with the Hypervolt 3 line only". Therabody prints "Compatible with PRO, Elite, Prime, Sense, Relief, Mini, G3PRO, G3 (sold separately)" on each head. Third-party sets advertise cross-compatibility, but fit varies. Buy from your gun's manufacturer and check the listing names your model.
What attachment is best for the neck and shoulders?
The softest head you have (dampener, cushion, or super-soft) on a low speed. These areas are sensitive and close to bone, so a hard ball or bullet is too intense. Keep the gun moving, avoid the front and sides of the neck entirely, and never use a massage gun on the spine, throat, or any pulse point.
Our Verdict
If you take one thing from this: the ball or standard head is the one you'll actually use, and it handles the large majority of recovery work on healthy muscle. Pair it with a soft dampener or cushion for anything tender and a bullet or cone for knots, and you have a complete kit. The other heads are nice-to-haves for specific jobs, not requirements.
When you're shopping for a gun, don't be swayed by the head count on the box. Check that it includes those two or three core shapes, that the material suits how you'll use it, and that the heads lock in securely. A gun with three well-chosen attachments beats one with eight you'll never fit.
