The ear cushions on your HD280s come off and snap back on in about two minutes

The ear cushions (also called ear pads or earcups) on Sennheiser HD280 headphones are replaceable parts held on by friction, not glue or screws. You pull the old one straight off the plastic ring underneath, then press a new one onto that same ring until it seats all the way around. The whole job takes longer to find the replacement cushions than to install them.

Sennheiser sells official replacement cushions under part number 504602, which fit the HD280 and several other Sennheiser models. You can also find third-party replacements online, though the official ones are usually under $30 and last longer. The cushions wear out from sweat, skin oils, and just the repeated compression of wearing the headphones — replacing them every two to three years is normal if you use them daily.

Key Takeaways

  • Sennheiser HD280 ear cushions pull straight off the plastic ring and press back on by hand — no tools needed.
  • Official replacement cushions are Sennheiser part number 504602 and cost around $20 to $30.
  • The old cushion comes off easiest if you pull from the edge where it meets the headband, not from the center.
  • The new cushion seats completely when you hear or feel a small click around the entire ring.

What you need before you start

You need the replacement cushions themselves — order Sennheiser part 504602 from the manufacturer's website, Amazon, B&H Photo, or any electronics retailer that stocks Sennheiser parts. Have them on hand before you remove the old ones, so your headphones are not sitting exposed while you wait for shipping.

You do not need any tools. The cushions are held on by a friction fit, which means they grip the plastic ring tightly enough to stay put during normal use but come off with steady hand pressure. A clean, flat surface to work on helps — your desk or a table where you can set the headphones down without them rolling.

How to remove the old ear cushions

Hold the headphone cup steady with one hand. With your other hand, grip the edge of the ear cushion where it meets the headband — not the center of the cushion, but the outer rim. Pull straight outward and slightly downward with steady, even pressure. The cushion will resist at first, then suddenly release as the friction breaks.

If the cushion is stuck, do not yank hard enough to bend the plastic ring underneath. Instead, work your way around the edge: pull a little on one side, then the opposite side, then the top and bottom, loosening it gradually. This spreads the force and prevents the ring from warping. Once one side comes free, the rest usually follows easily.

Set the old cushion aside. You will now see the plastic ring that the cushion was gripping. Wipe it clean with a dry cloth to remove any dust, dried sweat, or debris. A clean ring helps the new cushion seat evenly and grip properly.

How to install the new ear cushions

Take the new cushion out of its packaging. Line up one edge of the cushion with the corresponding edge of the plastic ring — start at the top, where the cushion meets the headband. Press that section down firmly until you feel it grip.

Work your way around the ring, pressing the cushion down in sections: top, then one side, then the other side, then the bottom. Use your thumbs or fingers to explore steady pressure, not a sharp poke. The cushion should seat smoothly without wrinkles or gaps. You will feel or sometimes hear a small click as the cushion locks into the friction fit all the way around.

Once both cushions are installed, put the headphones on and move them around. The cushions should not shift, slide, or feel loose. If one side feels like it is not seated fully, take the headphones off and press that section down again until it clicks into place.

When to replace your ear cushions

The cushions are ready to replace when they become hard, cracked, or sticky. New cushions are soft and slightly squishy; old ones compress and stay compressed, or they develop a tacky surface from degraded material. If the foam is flaking off or the covering is peeling, replacement is overdue.

You may also notice the headphones feel less comfortable or the seal around your ear is not as tight — that is usually a sign the cushion has lost its shape. Replacing them restores both comfort and sound isolation, since a worn cushion does not seal as well against your ear.

Extending the life of your new cushions

Cushions last longer if you store the headphones in a case or pouch when you are not using them. Exposure to direct sunlight, heat, and humidity speeds up the breakdown of the foam and covering material. If you use the headphones during workouts or in humid environments, wipe them down with a dry cloth after each use to remove sweat.

Avoid leaving the headphones in a hot car or near a heat source. The plastic ring can warp slightly if exposed to sustained heat, which makes the new cushions harder to install and can cause them to shift during use. A cool, dry storage spot — like a desk drawer or a padded case — keeps both the headphones and the cushions in better condition between replacements.

Frequently Asked Questions

Can I use third-party cushions instead of Sennheiser brand?

Yes, many third-party cushions fit the HD280 ring and cost less. However, official Sennheiser cushions usually last longer and maintain the original sound signature better. If you try a third-party option, check the return policy in case the fit is not quite right — some aftermarket cushions are slightly thinner or thicker than the original.

What if the plastic ring is cracked or broken?

If the ring itself is damaged, the cushion will not seat properly and will shift during use. The ring is part of the earcup assembly, which is a larger replacement part than just the cushion. Contact Sennheiser support with your headphone model number to order the correct earcup assembly, or check if a repair service in your area can replace it.

Do I have to replace both cushions at the same time?

You can replace one at a time, but it is usually better to do both together. If one cushion is worn enough to replace, the other is probably close behind. Replacing both at once ensures even comfort and consistent sound on both sides, and you avoid the hassle of doing the job twice in a few months.

Will replacing the cushions change how the headphones sound?

New cushions should restore the original sound, not change it. Worn cushions that no longer seal properly around your ear can make the bass sound thinner or allow outside noise to leak in. Fresh cushions restore that seal and bring the sound back to how the headphones sounded when they were new.

How long do replacement cushions usually last?

Official Sennheiser cushions typically last two to three years with daily use. Heavy use, sweat exposure, or storage in hot or humid conditions can shorten that lifespan. If you use the headphones occasionally or store them carefully, they may last longer.
