If you want fresh cooling-gel comfort for a pair of Sony WH-1000XM4 headphones you already own, choose Miruchertter WH-1000XM4; if you need to revive a set of Bose QuietComfort Ultra headphones with worn-out cushions, choose Duyfioa Replacement Ear Pads. These two products are not competitors in the usual sense. They are replacement ear pads built for two completely different headphones, and picking the wrong one is the fastest way to waste money.
• Miruchertter WH-1000XM4 — biggest strength: cooling gel layered with high-density memory foam, aimed at people whose ears overheat during long listening sessions.
• Miruchertter WH-1000XM4 — biggest trade-off: it is built for Sony WH-1000XM4 (WH1000XM4) headphones only, so it is useless if you own anything else.
• Duyfioa Replacement Ear Pads — biggest strength: a complete refresh kit for Bose QC Ultra headphones, including a pair of pads plus the pry tools you need to install them.
• Duyfioa Replacement Ear Pads — biggest trade-off: it fits Bose QC Ultra (Gen 1 & Gen 2) exclusively, and the manufacturer is explicit that you must confirm your model before buying.
• Who each pick is for: Miruchertter for Sony XM4 owners chasing cooler, denser padding; Duyfioa for Bose QC Ultra owners whose original cushions have flattened, cracked or started flaking.
This is a direct replacement for the stock earpads on Sony's WH-1000XM4 over-ear headphones. The headlining detail is the cooling gel layer sitting on top of high-density memory foam. In practice, that combination is about two things: a denser, more supportive cushion than tired factory foam, and a surface that is meant to feel less stuffy against the ear over a long stretch of listening. The brand frames it around noise isolation too, which makes sense — a memory-foam pad that seals properly around the ear is doing a lot of the acoustic work on a closed-back headphone.
Who should skip it? Anyone who does not own WH-1000XM4 headphones. The compatibility field is narrow and specific, and the model number listed in the item details is a WH-1000XM3 reference, which is a good reminder to double-check your own headphone's model before ordering anything. If you own Bose, Sennheiser, Audio-Technica or a gaming headset, this is not your product. If you simply want the cheapest possible foam pad and do not care about cooling, a basic replacement would do the same job.
Duyfioa Replacement Ear Pads: Who It's For
Duyfioa's pads are made for the Bose QuietComfort Ultra line — specifically the QC Ultra in both Gen 1 and Gen 2, including the newer QuietComfort Ultra (2nd Gen) wireless model. The material story here is memory foam wrapped in protein leather, with added thickness. That extra thickness matters more than it sounds: it is the difference between a pad that presses your ears against the driver housing and one that gives your ears a little breathing room. The manufacturer specifically calls out that it does not press on the ears, which is exactly the complaint people have when their original cushions have collapsed.
The kit is the other half of the pitch. You get a pair of pads (two count), an opening pick and a triangle opener, plus a written four-step process: pry the old cushion off the earcup seam, clean the dust and residue off the speaker scrim and tab grooves, align the left and right markings and the hinge notch, then press the flange down until every tab clicks. That is a genuinely useful inclusion, because Bose-style pads clip in with hidden tabs and doing it with a fingernail alone is an exercise in frustration. The grey color matches the grey QC Ultra finish, and the fit is stated to match the original size.
Who should buy it? Bose QC Ultra owners whose pads are visibly worn — flaking protein leather, flattened foam, a seal that no longer feels snug. It is also a sensible move if you bought a used or refurbished pair and want a clean start. There is a one-year manufacturer warranty, and the listing notes spare part availability for two years, which is a reasonable signal that the brand intends to stick around.
Who should skip it? Anyone who does not own Bose QC Ultra headphones. The compatibility statement is repeated and emphatic for a reason. Sony owners, standard QuietComfort (non-Ultra) owners, and Ultra Open earbud owners are all outside the fit.
• Best for Sony WH-1000XM4 owners → Miruchertter WH-1000XM4. Compatibility is the first filter, and this one is built for that exact headphone.
• Best for Bose QC Ultra owners → Duyfioa Replacement Ear Pads. Gen 1 and Gen 2 are both covered.
• Best for hot, sweaty ears → Miruchertter WH-1000XM4. The cooling gel layer is the distinguishing feature and nothing in the Duyfioa sheet claims the same.
• Best for a complete install kit → Duyfioa Replacement Ear Pads. Pry pick plus triangle opener plus a documented four-step method.
• Best for added cushion thickness and ear clearance → Duyfioa Replacement Ear Pads. The brand explicitly designs around not pressing on the ears.
• Best for a color match to your headphones → Duyfioa Replacement Ear Pads if you own grey QC Ultra, or Miruchertter WH-1000XM4 if you own black XM4.
• Best for a brand-new-headset look → Duyfioa Replacement Ear Pads, since the stated goal is restoring the headset's original appearance.
• Best for buyers who want a stated warranty → Duyfioa Replacement Ear Pads, which lists a one-year manufacturer warranty.
In my opinion, the honest answer is that these two products never compete — the headphone you already own decides it for you. If I owned Sony WH-1000XM4 headphones and wanted cooler, denser padding for long sessions, I would buy the Miruchertter set. If I owned Bose QC Ultra headphones with tired cushions, I would buy the Duyfioa kit, largely because the included tools and the four-step install guide remove the one part of pad replacement people actually dread. Check the current price on Amazon for whichever one matches your model, and confirm your headphone model before you order.
No. Miruchertter WH-1000XM4 fits Sony WH-1000XM4 (WH1000XM4) headphones. Duyfioa fits Bose QC Ultra Gen 1 and Gen 2. The mounting systems and earcup shapes are different, so neither will fit the other brand.
That is the design intent. The pads combine cooling gel with high-density memory foam, which is a different construction from a plain foam cushion. Whether it feels noticeably cooler to you depends on how warm your ears run and how long you listen.
Yes. You get an opening pick and a triangle opener with the pair of cushions. The manufacturer also walks through four steps: pry off the old cushion, clean the earcup interior, align the left/right markings and hinge notch, then press the flange until all tabs click.
If the headphones themselves work fine and only the cushions are worn, replacing the pads is the cheaper and less wasteful route. Worn pads affect comfort and the seal around your ear, and a fresh set restores both without touching the electronics. Check the current price on Amazon before deciding.
