If you want fresh pads for Sony MDR-7506 / V6 / CD900ST headphones, choose Niukeke Replacement Ear Pads; if you need replacement cushions that fit a wider spread of studio and hi-fi models — JVC HARX700/HARX900, AKG K240S/K271, Philips Fidelio X2 HR, ATH-AD1000X and SR850s — choose DowiTech HARX700.
• Niukeke — biggest strength: purpose-built for one headphone family. It's a dedicated fit for the Sony MDR-7506, MDR-V6 and MDR-CD900ST, with protein leather over memory foam and a 1-year manufacturer warranty.
• Niukeke — biggest trade-off: that focused fit is also its limit. The listing is explicit that it does not fit other Sony headphones, so you have to confirm your model before buying.
• DowiTech HARX700 — biggest strength: one pad, many hosts. It's designed around original-equipment dimensions and covers a broad compatibility list spanning JVC, AKG, Philips, Audio-Technica and SR850s.
• DowiTech HARX700 — biggest trade-off: broad fit means you're the one doing the verifying. It's a newer product with a shorter track record, and cross-model pads always carry a small risk of a slightly different feel around the ear.
• Who each is for: Niukeke for MDR-7506/V6/CD900ST owners who want a clean, drop-in refresh; DowiTech for owners of the listed JVC/AKG/Philips/AT models who want a cushion upgrade without hunting for model-specific pads.
Niukeke's whole pitch is renewal. If your Sony MDR-7506, MDR-V6 or MDR-CD900ST pads have gone shiny, flaky or flat, these are built to give the headphone a second life rather than send you shopping for a new one. The construction is protein leather on the outside over high-density memory foam inside — a slow-rebound foam that keeps its cushion instead of collapsing after a few weeks. The seam is stitched on the inside, which is the detail that matters most for longevity: interior stitching is what stops pads from splitting at the joint the way cheap glued pads do.
Installation is tool-free. You align the pad with the mounting posts inside the earcup and snap it into place. No glue, no prying, no trip to a repair bench — the kind of job you can finish while your coffee goes cold. The foam is paired with an ultra-thin acoustic layer that's breathable and dust-resistant, and Niukeke claims it helps seal off outside noise rather than leak sound out. That's the practical part: a proper seal is what keeps bass from escaping and keeps office chatter, train rumble and air-conditioning hiss from pressing in.
DowiTech HARX700: Who It's For
DowiTech takes the opposite approach. Instead of one headphone family, the HARX700 pad is made to the dimensions of original equipment and covers a genuinely wide set: JVC HARX700 and HARX900, SR850s, AKG K240S and K271, Philips Fidelio X2 HR, and Audio-Technica ATH-AD1000X. That's a mix of budget studio cans, classic AKG monitoring models and open-back hi-fi headphones — three different crowds served by one cushion.
The materials story is familiar but well executed on paper: soft protein leather with the texture and hand-feel of real leather, over high-density professional memory foam. DowiTech's framing is about fatigue — the foam is meant to be both soft and elastic, holding its shape through repeated use rather than going mushy. The leather surface is described as smooth and abrasion-resistant, which is what you want on a part that rubs against glasses arms, hair and skin every single day. The brand also notes its team checks each production step from material selection through quality control.
The installation angle is worth reading carefully. DowiTech says the pads are designed and manufactured according to the original headphone, so they should fit your model precisely — and it invites you to contact them if you hit an installation snag. That's honest, but it's also a signal: with a compatibility list this broad, there will be models where the fit is slightly tighter or looser than stock, and the brand is positioning support as the safety net. On the plus side, that support includes free replacement or refund for defects or compatibility problems, with a stated 24-hour response window.
Buy DowiTech if you own one of the listed JVC, AKG, Philips, Audio-Technica or SR850 models and want a cushion upgrade without chasing a model-specific listing. Think twice if your headphone isn't on that list, or if you'd rather have a part engineered for exactly one headphone rather than a broad range.
• Own Sony MDR-7506, MDR-V6 or MDR-CD900ST → Niukeke Replacement Ear Pads. It's built for those three and nothing else.
• Own JVC HARX700/HARX900, AKG K240S/K271, Fidelio X2 HR, ATH-AD1000X or SR850s → DowiTech HARX700. It's the one that actually lists your model.
• Want the tightest fit guarantee → Niukeke. A three-model compatibility list leaves very little room for a wrong fit, provided your model is on it.
• Want one pad that covers several headphones in your house → DowiTech HARX700. Its range spans multiple brands and form factors.
• Long-term durability priority → Niukeke, on paper. Inside-seam stitching plus a 1-year manufacturer warranty is a sturdier proposition than an unstated construction detail.
• After-sales safety net → DowiTech HARX700. A stated 24-hour response and free replacement or refund for defects or compatibility issues is unusually explicit.
• Material preference → a wash. Both use protein leather over memory foam. Niukeke calls its foam slow-rebound and dense; DowiTech calls its foam high-density and shape-retaining. Same family of materials, different marketing.
• Care about isolation → either, with a caveat. Neither pad can change what your headphone fundamentally is. A sealed Sony will still isolate better than an open-back Fidelio X2 HR — pads help, they don't transform.
In my opinion, the right pick here is decided entirely by what's sitting on your desk, not by which pad is "better." If I owned an MDR-7506 or MDR-V6, I'd buy the Niukeke Replacement Ear Pads — a three-model compatibility list, inside-seam stitching and a one-year manufacturer warranty is about as low-risk as a pad swap gets.
If my headphones were a JVC HARX700/HARX900, an AKG K240S/K271, a Fidelio X2 HR or an ATH-AD1000X, I'd buy the DowiTech HARX700 without hesitation, because Niukeke simply doesn't make a pad for them.
Before either purchase, confirm your exact headphone model. That single check matters more than any spec on this page.
FAQ
No. They're compatible with the Sony MDR-7506, MDR-V6 and MDR-CD900ST only. The brand states clearly that they do not fit other Sony models, so check your model number on the headband before ordering.
They're listed as compatible with JVC HARX700 and HARX900, SR850s, AKG K240S and K271, Philips Fidelio X2 HR and ATH-AD1000X. If your model isn't on that list, don't assume it'll work — confirm first.
Prices change often, so check the current price on Amazon using the button on this page rather than relying on any figure you've seen elsewhere. Value also depends on fit: a cheaper pad that doesn't match your headphone is worth nothing.
Yes, to a degree. A properly sealing pad restores bass response and blocks more outside noise than a flattened, cracked one. Both options use protein leather over memory foam for that reason — but pads refine your headphone's character, they don't change what it is.
