The ear cushions on HD280s come off by twisting and pulling, and new ones snap back on the same way

The Sennheiser HD280 ear cushions wear out faster than the rest of the headphone because your ears create heat and moisture inside them. When they crack, peel, or stop sealing sound properly, you can replace them without tools in about two minutes. The cushions twist counterclockwise to release, then pull straight off the ear cup. New cushions twist clockwise to lock back on.

You will need replacement ear cushions made for the HD280 — Sennheiser sells them as a pair under part number 504602. Third-party cushions exist, but they fit differently and may not seal as well. The official replacements cost between $20 and $35 depending on where you buy them.

Key Takeaways

  • Twist the old cushion counterclockwise while holding the ear cup steady, then pull it straight off the headphone.
  • The replacement cushion has a plastic ring that slots into a groove on the ear cup — align it before you start twisting.
  • Twist the new cushion clockwise until it stops and sits flush against the ear cup with no gaps.
  • Both cushions should feel equally tight; if one spins easily, it is not seated all the way and will fall off during use.

Remove the old cushion by twisting counterclockwise

Hold the headphone frame steady with one hand so the ear cup does not rotate while you work. Grip the old cushion with your other hand and twist it counterclockwise — the direction your thumb points when you make a thumbs-down gesture. You will feel resistance for the first quarter-turn, then it loosens. Do not force it; if it is stuck, try twisting back and forth a few degrees to break the seal.

Once the cushion turns freely, pull it straight away from the ear cup. It will come off completely. Do not twist and pull at the same time — twist until it is loose, then pull. The plastic ring underneath the cushion will stay attached to the ear cup; that is correct and normal.

Align the new cushion before twisting it on

The replacement cushion has a plastic ring molded into the bottom. This ring slides into a groove that runs around the ear cup. Before you twist, hold the cushion above the ear cup and line up the ring with the groove — you should see the ring sit into the groove all the way around with no gaps. This takes a few seconds and prevents the cushion from going on crooked.

If the ring does not sit into the groove evenly, the cushion is tilted. Lift it off and try again. Getting this alignment right the first time makes the twist-on much easier and ensures the cushion seals properly against your ear.

Twist the new cushion clockwise until it locks

Once the ring is seated in the groove, twist the cushion clockwise — the direction your thumb points when you make a thumbs-up gesture. You will feel it tighten as the threads engage. Keep twisting until the cushion stops and will not turn any further. This usually takes a half-turn to a full turn depending on where the ring started.

When the cushion is fully seated, it should sit flush against the ear cup with no visible gaps between the cushion and the plastic frame. Run your finger around the edge to check. If you see a gap anywhere, untwist it, pull it off, and start over — the ring is not in the groove correctly.

Check that both cushions are equally tight

Try to twist each cushion by hand. They should both resist equally and feel snug. If one cushion spins easily while the other is tight, the loose one is not fully seated. Remove it and check that the ring is in the groove all the way around, then twist it back on.

A cushion that is not fully locked will shift during use and eventually fall off inside your ear or drop onto your shoulder. Spending an extra 30 seconds to verify both are equally tight prevents this. Once both cushions are snug, your HD280s are ready to use.

What to do if a cushion will not come off

If the old cushion is stuck and will not twist, it has probably bonded to the plastic ring underneath from age and heat. Try twisting back and forth in small motions — a quarter-turn in each direction — to break the bond without forcing it. You can also try gently prying the edge of the cushion with your fingernail to create a small gap, then twisting again.

If it still will not budge, let the headphone sit in a warm room for 30 minutes. Heat softens the adhesive and makes the cushion easier to remove. Do not use a heat gun or hair dryer — too much heat can warp the plastic ear cup. Once it comes off, clean any old adhesive residue from the plastic ring with a dry cloth before putting the new cushion on.

Frequently Asked Questions

Can I use third-party ear cushions instead of Sennheiser ones?

Third-party cushions fit the HD280 but often do not seal as tightly or last as long as the official Sennheiser replacements. Some have a different ring design that does not lock as securely. If you want to try them, make sure the listing specifically says they fit the HD280 and read the reviews for reports of loose fit or durability problems.

How long do replacement cushions usually last?

Most people get two to four years of use before the cushion starts to crack or peel, depending on how often you wear the headphones and how much you sweat. Keeping them in a cool, dry place and wiping them down after use extends their life. When they start to deteriorate, replace them rather than trying to repair them with tape or glue.

What if I lose one cushion and only have one replacement?

You can wear the headphones with one new cushion and one old one temporarily, but they will not sound the same on both sides because the seal is different. Order a second replacement cushion so both ears match. Mismatched cushions also look uneven and may not fit your ears the same way.

Do I need to replace the ear cup if the plastic ring is cracked?

If the plastic ring itself is cracked or broken, the cushion will not lock on securely no matter how tight you twist it. You will need to replace the entire ear cup assembly, not just the cushion. Contact Sennheiser support with your headphone model number to order the correct replacement ear cup.
