⭐ Fresh foam ear cushions for your Sony WH-CH400
The Sony WH-CH400 is a headphone that tends to stay in use for years: everyday listening, the commute, travel, long evenings. With every use the ear cushions are compressed, warmed and exposed to sweat and skin oils. They are wear parts and age long before the rest of the headphones do.
The cushioning foam is the first thing to give out: it loses its spring, flattens and hardens in places. The covering then cracks or flakes. The headphones press harder, sit less evenly and look tired, even though they usually still work perfectly.
These replacement ear cushions for the Sony WH-CH400 let you renew only the worn part. It is quick, simple and far cheaper than buying a new pair of headphones. If you are searching for ear pads, ear cushions or foam cushions for the Sony WH-CH400, this is the pair.

🧽 Foam: the heart of headphone comfort
An ear cushion is made of the cushioning foam, the PU leather cover and the attachment area that fits onto the ear cup. The foam does four essential jobs.
🛋️ It cushions
It spreads pressure around the ear for long listening sessions.
🔒 It holds
It follows the shape of your ear and keeps the headphones in place.
🎚️ It shapes the sound
It sets the distance and air between the driver and your ear.
📐 It keeps its shape
It preserves the cushion's profile in front of the driver.
When the foam wears out, comfort, fit and tonal consistency all suffer. Replacing your ear cushions is the most effective way to get the enjoyment back from your headphones.
🩺 How to tell your ear cushions are worn out
📉 Flattened cushions
The foam no longer bounces back.
🪨 Hardened foam
Some areas are firmer and press on your ears.
🧩 Foam crumbs
Powder or small pieces escape from the cover.
🩹 Peeling cover
The PU leather cracks or comes away.
😣 Sore ears
The headphones become uncomfortable quickly.
🔊 Thinner bass
A looser fit and a sound that loses body.
👃 Lingering smell
Sweat has soaked into the foam.
✅ Headphones still work
Only the ear cushions need replacing.
🧪 The 3-step foam check
- Thumb test: press the center of the ear cushion and release. If the dent stays, the foam is tired.
- Touch test: run your fingers around the cushion. Hard, uneven or lumpy foam is at the end of its life.
- Visual check: inspect the edges and seams. Cracks, tears or crumbs confirm the wear.
🔎 Compatibility: Sony WH-CH400
These ear cushions are offered for the Sony WH-CH400 headphones. Sony makes many models with similar shapes, so take a minute to confirm your model before ordering.
How to find your Sony model name
- Check the headband: the model name is usually printed there.
- Look at the ear cups: a left / right marking or the model number is often on them.
- Find the original box or manual.
- Check your invoice or order history.
🛡️ Why PU leather?
🧼 Quick to clean
A wipe with a slightly damp cloth handles everyday care.
🛡️ Foam protected
The closed surface helps keep dust and sweat out of the foam.
🎒 Travel friendly
Copes well with handling and storage in a bag or case.
✨ Refreshed look
New ear cushions give your headphones a tidy, even appearance again.
🔊 Sound and fit: what new ear cushions can do
How a headphone sounds depends not only on the driver but also on the fit of the ear cushions. When they sit evenly and the foam is fresh, bass and detail come through more consistently. When they are flattened or uneven, part of that is lost.
Good to know
- Fresh foam improves fit and evenness.
- A secure fit supports steadier bass.
- Results also depend on head shape, glasses and how you wear the headphones.
- Ear cushions are wear parts and do not change the headphones' drivers or electronics.

Allow a few minutes and work gently.
- Set up a clean, well-lit surface with a soft cloth.

🛠️ Small problems, simple fixes

- A wrinkle appears: lift the area slightly, smooth it out and press it back down gradually.
- An edge lifts: take it off and press it back evenly all the way around.

❓ FAQ: Sony WH-CH400 foam ear cushions
Do these ear cushions fit the Sony WH-CH400?
Yes, they are offered for this model. Still, check the name printed on your headphones before ordering.
Are ear cushions the same thing as ear pads?
Yes. "Ear cushions" and "ear pads" are two names for the same part: the foam cushions that sit around your ears.
Do they also fit the Sony WH-1000XM4, WH-1000XM3 or WH-CH710N?
Not necessarily. Sony models have different ear cushions. Each of these models has its own page, linked at the bottom of this page.
In which colors are they available?
In black, gray and blue. Choose the color that matches your headphones.
What material are they made of?
PU leather covering with fresh foam cushioning inside.
Why does the foam in ear cushions wear out?
It is compressed with every use and exposed to heat, sweat and skin oils. Eventually it flattens, hardens or crumbles.
What is included in the order?
One pair of ear cushions (left and right) in your chosen color. The headphones are not included.
Is installation difficult?
No. You remove the old ear cushions and fit the new ones, usually with no special tools. The guide above covers every step.
Should I replace both ear cushions?
Yes, it is recommended. The foam wears the same way on both sides, and a fresh pair gives balanced comfort.
Will the sound change?
Slight differences are possible depending on thickness and material. Fresh foam generally gives a better fit and steadier bass than crushed ear cushions.
How do I know my ear cushions are worn?
Flattened cushions, hard spots, foam crumbs, a peeling cover or sore ears are the most common signs.
How do I clean PU leather ear cushions?
Wipe them with a slightly damp cloth, avoid solvents and strong alcohol, and dry the surface afterwards.
My headphones still work. Is it worth changing the foam?
Yes, that is the ideal case. You keep headphones that work and renew only the wear part, at a fraction of the cost of new headphones.
How long do new ear cushions last?
It depends on how much you use them, how much you sweat, how you store them and how you care for them. Regular cleaning helps preserve the foam.
Can I fit them myself?
Yes. No special skills are needed. Just work gently, especially when pulling off the old ear cushions.
