If you want a replacement pad specifically engineered for the COWIN E7 / E7 Pro and Silensys E7 family, choose defean Earpads; if you need a generic soft-leather pad with a strong acoustic-seal pitch for 600/500-style cans, choose HOMSFOU Earpads Noise Isolation. That's the short version. The longer version is about fit certainty, warranty backing, and how each pad actually seals against your head.
• defean's biggest strength: it is a model-specific pad — round, leather, and built for COWIN E7 / E7 Pro and Silensys E7 / E7 Pro, so fit is the whole point.
• defean's biggest trade-off: it will not fit everything. The listing is explicit that it does not fit the COWIN SE7, and it warns that if your headphone uses elliptical pads, you should not buy it.
• HOMSFOU's biggest strength: a broad "noise isolation" design story — soft leather over sponge with an internal super padding layer, sized at 4.72 x 3.54 x 1.18 inches and aimed at 600/500-type headphones.
• HOMSFOU's biggest trade-off: it is a generic replacement pad. Compatibility is described loosely ("for 600/500"), and the manufacturer states plainly there is no warranty.
• Pick defean if you own a COWIN E7, E7 Pro or Silensys E7 and want a like-for-like round pad plus a 12-month warranty.
• Pick HOMSFOU if you're refreshing a 600/500-style headphone and you prioritize a soft, breathable leather-and-sponge feel over brand-matched fit.
The defean pad is a compatibility-first product. The headlining fact is right in the name: COWIN E7 / E7 Pro (and not the SE7), plus Silensys E7 / E7 Pro. If that's your headphone, you already know why this matters. Replacement pads live or die on whether they mount cleanly, and defean answers that with a round, black leather pad matched to those specific models. The listing even flags the geometry trap most buyers fall into: the COWIN E7 uses round ear pads, so if your headphone takes elliptical pads, this is not your product.
The second thing defean sells is reassurance. There's a stated 12-month worry-free warranty and free lifetime technical support, plus a service promise covering replacement or refunds if something goes wrong. For a small consumable part that you'll be pressing onto a headband with your own hands, that backing is worth more than it sounds. The brand also positions the pads as produced under strict quality inspection and as a way to restore "the same quality as the original" when your stock pads are worn out — cracked leather, flattened foam, that dull feeling when the seal stops working.
Where it falls short: it is not a universal pad. If you don't own a COWIN E7 / E7 Pro or a Silensys E7 / E7 Pro, this is simply the wrong product, no matter how good the foam is. The elliptical-shape warning is real and worth taking literally. And there is one practical friction point — defean notes that installation can be fiddly and points to an installation video guide for help. That's a hint that first-timers may need a few minutes and a second attempt before the pad seats properly. It's not a dealbreaker, but don't expect a one-second snap-on.
Who should buy it: owners of COWIN E7 / E7 Pro or Silensys E7 / E7 Pro with round pads who want a model-matched replacement and value having warranty coverage behind it.
Who should skip it: anyone with a COWIN SE7, anyone whose headphone uses elliptical pads, and anyone who wants a generic pad they can move between different headsets.
HOMSFOU's pitch is quieter and broader. This is a soft leather-and-sponge replacement pad sized at 4.72 x 3.54 x 1.18 inches, targeted at 600/500-style headphones, and the entire feature list circles one idea: sealing out the outside world. The listing describes an acoustic seal as the core function, a memory cushion that blocks outside sound from entering, and internal super padding that stays comfortable through all-day listening. The claim that you don't need to break them in — that they feel right from day one — is the kind of thing a buyer notices immediately if it holds up.
Materials-wise, it's black leather over sponge, described as skin-friendly, breathable and absorbent. HOMSFOU also says the pads preserve your headphone's original sound and can even add vibrancy, which is the standard argument for a tighter seal: less leakage in, less leakage out. Physically, these are a compact pad — roughly 4.7 inches long by 3.5 inches wide by a little over an inch thick — so they suit smaller, rounder earcups rather than big over-ear shells. The listing also frames them as a fix for old, broken, cracked or damaged pads, which is honest about what a replacement pad actually is.
The trade-offs are worth stating plainly. First, compatibility is vague. "For 600/500" is not a model number you can verify against your own headphone the way you can with defean's COWIN/Silensys list, so you'll want to measure your existing pads before ordering. Second, the manufacturer lists no warranty — the opposite of defean's 12-month coverage. Third, the descriptive text in the listing is repetitive and machine-flavored, which tells you less about real-world durability than a clean spec sheet would. None of that makes it a bad pad; it just means the burden of confirming fit falls on you.
Who should buy it: someone refreshing a 600/500-type headphone who wants a soft, breathable leather pad with a strong seal-focused design and doesn't need brand-specific fit guarantees.
Who should skip it: anyone who needs a confirmed match for a named headphone model, anyone who wants warranty protection, and anyone with larger earcups that these compact dimensions won't cover.
Side-by-Side: Which Should You Choose?
• Own a COWIN SE7 → neither of these as a confirmed match. defean explicitly excludes the SE7.
• Headphone uses elliptical pads → skip defean. It states the E7 needs round pads and warns elliptical owners away.
• Refreshing a 600/500-style headphone → HOMSFOU Earpads Noise Isolation. That's the model range it's built around.
• Want warranty coverage → defean Earpads. A 12-month warranty and lifetime technical support versus HOMSFOU's stated no-warranty term.
• Want the most explicit noise-isolation design language → HOMSFOU. Acoustic seal, memory cushion, internal super padding — sealing is its entire identity.
• Want installation help if you get stuck → defean. It points to an installation video guide; HOMSFOU only says the pads are easy to mount and detach.
• Want a specific, measurable footprint → HOMSFOU. It publishes dimensions (4.72 x 3.54 x 1.18 in); defean's sheet gives shape and material but not measurements.
In my opinion, I'd buy the defean Earpads — but only if I owned one of the headphones it names. Specificity beats generality with replacement pads, because a pad that doesn't seat properly doesn't isolate anything, and defean tells you exactly which models it fits and which it doesn't. Add the 12-month warranty and the installation guide and it's the lower-risk purchase for the right owner.
If I had a 600/500-style headphone and didn't care about brand-matched fit, I'd take the HOMSFOU Earpads Noise Isolation instead — the soft leather-and-sponge build and the published dimensions make it a reasonable generic option. Just measure first, and go in knowing there's no warranty behind it. Before either purchase, check the current price on Amazon using the button on this page.
No. The defean listing states compatibility with COWIN E7 / E7 Pro and specifically notes it does not fit the SE7 model. It also warns that if your headphone uses elliptical pads, you shouldn't buy it — the COWIN E7 takes round pads.
Not any headphone. HOMSFOU describes them for 600/500-style headphones and gives dimensions of 4.72 x 3.54 x 1.18 inches. Measure your existing pads and compare before ordering, since the listing doesn't name specific models the way defean does.
HOMSFOU leans harder on noise isolation in its design description — acoustic seal, memory cushion, internal padding — while defean focuses on high-density noise-cancelling foam and exact fit for named models. A correct fit is what makes a seal work, so compatibility matters as much as the foam itself.
defean offers a 12-month worry-free warranty plus free lifetime technical support. HOMSFOU lists no warranty. That difference is worth weighing if you want protection against a pad that tears or flattens early.
