• COMPLY Memory Foam Replacement — biggest strength: contoured memory foam plus patented SmartSkin, a moisture-resistant surface built for long, sweaty listening sessions.
• COMPLY Memory Foam Replacement — biggest trade-off: it only fits Bose QuietComfort Ultra Gen 1 and Gen 2, so it is useless on any other headphone.
• YDYBZB Replacement Earpads — biggest strength: a protein leather and high-density memory foam combo that seals the ear and lifts passive isolation on the Px7 S3.
• YDYBZB Replacement Earpads — biggest trade-off: a single-model fit for Bowers & Wilkins Px7 S3 only, with no moisture-resistant coating mentioned.
• Who COMPLY is for: Bose QuietComfort Ultra owners who want a fresh, hygienic, noise-blocking cushion.
• Who YDYBZB is for: Bowers & Wilkins Px7 S3 owners who want a soft, skin-friendly refresh with clear L/R markings.
COMPLY builds this pad around one idea: a snug, contoured over-ear cushion that maximizes noise isolation while staying comfortable for hours. The memory foam is soft and breathable, and the ergonomic shape is designed to sit securely around the ear rather than press on it. That matters most on a headphone whose whole appeal is quieting a plane cabin or an open office.
Buy it if you own Bose QuietComfort Ultra Gen 1 or Gen 2 headphones and the original cushions have flattened, gotten grimy, or lost their seal. Skip it if you own anything else. COMPLY states plainly that these fit the QuietComfort Ultra only, so verify your model before ordering. There is no universal sizing here, and no adapter for other Bose lines.
YDYBZB Replacement Earpads: Who It's For
YDYBZB takes a different route: protein leather over high-density memory foam. The leather gives a soft, skin-friendly touch and reduces friction against the ear, while the foam cushions and absorbs pressure. The combination is meant to conform to the ear while still letting air circulate, so long sessions do not feel hot and pinched.
The high-density foam is also doing acoustic work. A dense pad that hugs the ear contour seals better, which raises passive noise isolation and, per the brand, sharpens resolution and beat detail. The full-enclosure design leans into that: block the room, hear more of the mix. That is the honest pitch for a closed-back wireless headphone like the Px7 S3, and it is a reasonable one.
Buy it if you own Bowers & Wilkins Px7 S3 headphones and want a softer, more immersive feel plus a tighter seal. The pads ship as two black cushions with clear L/R markings, which speeds up installation and stops the classic left-right mix-up. Skip it if you own any other Bowers & Wilkins model — the listing is explicit that it does not fit other series. There is a one-year warranty on the pair.
Side-by-Side: Which Should You Choose?
• Your headphones are Bose QuietComfort Ultra Gen 1 or Gen 2 → COMPLY Memory Foam Replacement. YDYBZB will not fit.
• Your headphones are Bowers & Wilkins Px7 S3 → YDYBZB Replacement Earpads. COMPLY will not fit.
• Best for moisture and hygiene → COMPLY. SmartSkin is moisture-resistant and easy to clean.
• Best for passive noise isolation → a tie. COMPLY uses a contoured seal; YDYBZB uses high-density foam and a full-enclosure design.
• Best for quick, foolproof installation → YDYBZB. Snap-on works for COMPLY too, but YDYBZB's L/R markings make alignment obvious.
• Best for long, hot listening sessions → COMPLY. Breathable foam plus a wipe-clean surface is the more sweat-friendly package.
In my opinion, the right pick is decided almost entirely by which headphones you own, because these two pads are not interchangeable. If you have Bose QuietComfort Ultra Gen 1 or Gen 2, I would buy the COMPLY Memory Foam Replacement: the memory foam contour and the SmartSkin surface make it the more durable, more hygienic choice for daily noise-isolating use. If you have Bowers & Wilkins Px7 S3, I would buy the YDYBZB Replacement Earpads for the soft protein leather feel and the tighter seal. Check the current price on Amazon before you commit, since both are easy swaps that cost far less than new headphones.
can you sleep with over ear headphones
You can, but it is not ideal. Both of these pads are contoured over-ear cushions designed for seated listening, not for lying on a pillow, where the headband and cups get pressed against your head. If you do, the softer protein leather of the YDYBZB pads will feel gentler against the ear than a firmer seal.
how to wear over ear headphones
Set the headband on the crown of your head and rotate each cup so the cushion surrounds the ear rather than sitting on it. The COMPLY pads are ergonomically contoured to seal around the ear, and the YDYBZB pads have L/R markings so you place each side correctly before you adjust anything.
how to wear over ear headphones properly
Center the headband, then slide the cups down until the foam fully encircles each ear with no gap at the top or bottom. COMPLY notes that proper installation and alignment matter for fit, comfort and listening performance, so take a moment to seat the pads evenly before judging the seal.
how should over ear headphones fit
Snug but not clamping. The pads should seal around the ear for isolation without pressing hard enough to ache after an hour. COMPLY's contoured design targets that secure, isolating fit, while YDYBZB's breathable protein leather and memory foam are built to conform without pressure over long sessions.
