If you want a replacement pad set built for one specific, well-known studio headphone family and nothing else, choose Niukeke Replacement Ear Pads; if you need a universal two-piece set that fits most over-ear headphones and don't care about exact model matching, choose Pengcadent 2PCS.
• Niukeke's biggest strength: purpose-built for the Sony MDR-7506, MDR-V6 and MDR-CD900ST, with protein leather, memory foam and a stated one-year manufacturer warranty.
• Niukeke's biggest trade-off: it will not fit other Sony models or any other brand — the listing is explicit that it only fits those three.
• Pengcadent's biggest strength: a universal "fits most over-ear headphones" design sold as a two-piece set, with thicker foam aimed at noise isolation.
• Pengcadent's biggest trade-off: no specific model list, no stated warranty, and no dimensions — so fit is a judgement call on your part.
• Pick Niukeke if you own a Sony MDR-7506, MDR-V6 or MDR-CD900ST and want a drop-in match.
• Pick Pengcadent if your headphones aren't in that Sony trio and you want a general-purpose pair of cushions.
Niukeke does one thing and says so plainly: these pads are compatible with the Sony MDR-7506, MDR-V6 and MDR-CD900ST. That's it. The listing even warns in capitals that they don't fit other Sony headphones, which is unusual honesty in this category and worth taking at face value. If your model number matches, you're in the right place. If it doesn't, stop reading and move on.
The materials are the standard premium combo for this job: soft protein leather over memory foam. Protein leather is the softer, more supple cousin of generic PU leather, and Niukeke leans into that — the pitch is breathability, no clammy feeling over long sessions, and a surface that stays comfortable against the ear for hours. The foam is described as slow-rebound and dense, which matters more than it sounds: dense foam is what holds its shape after months of compression instead of flattening into a pancake.
The design details are where this set earns its place. The stitching sits on the inside seam, which is a smart choice — the outside seam is exactly where cheap pads split first. There's also an ultra-thin acoustic foam layer described as dust-proof, breathable and sound-leak resistant, and the pads are sized at roughly 3.77 by 3.07 by 0.7 inches. Installation needs no tools: you align the pads with the mounting posts inside the earcups and snap them in.
Pengcadent 2PCS: Who It's For
Pengcadent takes the opposite approach. Instead of naming models, it says the pads are designed to fit most over-ear headphones. That's a broader promise, and a vaguer one. There's no compatibility list, no measurements, and no warranty mentioned — so the burden of checking your earcup size and mounting style falls on you before you order.
What the set does offer is a complete two-piece package, one pad per ear, which is what most people actually need. The material story is protein leather imported from Japan over memory foam, and the comfort pitch mirrors Niukeke's: soft against the skin, supportive over long wear. Pengcadent's specific angle is thickness. The pads are built with increased thickness specifically to match the original pads' noise isolation, which is a real consideration — worn-out pads go thin, thin pads leak bass and let in more outside noise, and replacing them restores both.
The construction is described as robust and resilient, aimed at surviving daily wear and tear over years rather than a single season. Installation is tool-free: pull the old pads, press the new ones on, done.
Who should buy it: anyone with a non-Sony over-ear headphone, or a Sony model outside the MDR-7506/V6/CD900ST trio, who wants a general-purpose two-piece set with an emphasis on isolation. Who should skip it: anyone who wants a guaranteed model-specific fit, exact dimensions, or a stated warranty — this set gives you none of those, and if your headphone has an unusual mounting ring, a universal pad is a gamble.
Side-by-Side: Which Should You Choose?
• Best for non-Sony headphones → Pengcadent 2PCS. It's the only one of the two that even claims broad over-ear compatibility.
• Best for buyers who want dimensions before ordering → Niukeke. Roughly 3.77 x 3.07 x 0.7 inches is published; Pengcadent publishes no measurements.
• Best for noise isolation emphasis → Pengcadent 2PCS. Its design brief centers on increased thickness to match original isolation.
• Best for long-session comfort → a tie, on paper. Both use protein leather over memory foam; neither material is inherently better here.
• Best for warranty coverage → Niukeke. A one-year manufacturer warranty is stated; Pengcadent states none.
• Best for durability engineering → Niukeke, in my reading. Inside-seam stitching is a concrete anti-cracking design choice, not just a claim.
• Best value for a two-ear replacement → Pengcadent, conditionally. Both ship as a pair, but Pengcadent is the more flexible pick if you're unsure of your model.
I'd buy the Niukeke pads — but only if I owned a Sony MDR-7506, MDR-V6 or MDR-CD900ST. The named compatibility list, the published dimensions, the inside-seam stitching and the one-year warranty give me things I can actually verify before ordering, and for a headphone this widely used, a precise match is worth more than flexibility. Pengcadent is the smarter buy if your headphones fall outside that Sony trio, because it's genuinely the only option here that will even attempt to fit them. Check the current price on Amazon for both before you commit — the fit question should decide this, not the cost.
No. Niukeke states compatibility only with the MDR-7506, MDR-V6 and MDR-CD900ST, and explicitly warns the pads do not fit other Sony headphones. For anything outside those three, look at a universal set like Pengcadent 2PCS instead.
Pengcadent says the pads are designed to fit most over-ear headphones, not all of them. There's no model list and no dimensions published, so measure your existing pads and check your mounting style before ordering.
Pengcadent is built around increased thickness specifically to match the original pads' noise isolation, so that's its stated focus. Niukeke relies on dense memory foam plus an ultra-thin acoustic foam layer for sound-leak resistance. Both approaches target the same problem — worn pads letting noise in.
Yes. Both are two-piece sets, giving you one replacement pad for each ear. Pengcadent states "2PCS" in the name and lists two pads in the package; Niukeke's pads are sold as a matching set for both earcups.
