• YDYBZB Ear Pads Replacement — biggest strength: an unusually broad compatibility list, covering Sony MDR-ZX110, ZX110NC, ZX310, ZX330BT, WH-CH500, CH510, CH520, V150, V250 plus a long run of JBL Tune models (510BT, 500BT, 450BT, 660NC, 600BTNC).
• YDYBZB Ear Pads Replacement — biggest trade-off: because it is built to span so many models, it is a general-purpose cushion rather than a factory-exact match for any single headphone, and it ships as pads only.
• Duyfioa Replacement Ear Pads — biggest strength: a tight, deliberate fit for one family of headphones (Sony MDR-7506, MDR-V6, MDR-V7, MDR-CD900ST), with added thickness and a stated 1-year manufacturer warranty.
• Duyfioa Replacement Ear Pads — biggest trade-off: the compatibility list is narrow, and the brand itself warns you to confirm your model before buying — these will not fit the ZX or WH-CH series at all.
• Who each pick is for: YDYBZB for owners of mainstream Sony/JBL wireless and wired on-ears; Duyfioa for owners of the classic folding Sony studio monitors.
The YDYBZB pads are the practical, wide-net option. The compatibility list is the headline here: MDR-ZX110 and ZX110NC, ZX310, ZX330BT, WH-CH500, CH510, CH520, V150, V250, and then the JBL side with Tune 510BT, 500BT, 450BT, 660NC and 600BTNC. That is a lot of ground for one pair of cushions, and it tells you the manufacturer designed this as a universal-style replacement for the popular on-ear and light over-ear models people actually use day to day — commuter headphones, gym pairs, the set that lives in a backpack.
The materials are what you would expect at this tier, and they are sensible: protein leather over memory foam. YDYBZB leans on the memory foam as a functional element, not just a comfort one — the firmer foam is meant to conform to the ear so the seal isolates more outside noise while keeping the sound lively. The brand also calls out crack-free durability from the leather and the fact that the pads relieve clamping pressure, which is the specific complaint people have after an hour or two with tight on-ears.
Who should buy it: anyone whose Sony ZX/WH-CH or JBL Tune pads have flattened, flaked or started shedding. Who should skip it: MDR-7506, MDR-V6, MDR-V7 and MDR-CD900ST owners — those models are not on the list, and forcing a pad onto the wrong cup is how you end up with a loose, leaky seal. Also skip if you want installation tools in the box, because YDYBZB ships pads only, no headphone and no accessories.
Duyfioa goes the opposite direction: narrow and precise. This pad exists for one lineage of headphones — Sony MDR-7506, MDR-V6, MDR-V7 and MDR-CD900ST — and the brand states plainly that you should confirm your model before ordering. In my opinion that honesty is a feature, not a limitation. These are headphones with a very particular cup geometry and a devoted owner base (studio, editing, monitoring), and a pad that is the "same size as the original" is exactly what that buyer wants.
The construction matches the intent. Memory foam with added thickness, wrapped in protein leather, described as soft, durable and not pressing on the ears — that last point matters on the 7506 family, because a thin or collapsed pad is what makes those headphones feel like they are pinching after a long session. Duyfioa also frames this as a cosmetic refresh: new cushions give a tired headset a brand-new look, which is a fair way to describe what a pad swap actually accomplishes on a well-built but worn pair.
The detail that separates it from YDYBZB is the install kit. You get an opening pick and a triangle opener, and the brand walks through a four-step process: peel the old pads off gently, clean residue off the earcup, align and snap the new pads into the grooves, then press the edges flat to kill any gaps. If you have ever wrestled a stiff lip onto a studio cup with bare fingers, you understand why the tools matter. Duyfioa also backs the pads with a stated 1-year manufacturer warranty.
Who should buy it: MDR-7506 / V6 / V7 / CD900ST owners doing a repair or refresh. Who should skip it: everyone else — if your headphones are ZX110, WH-CH510 or JBL Tune, this pad is not built for you.
• Best for wide compatibility → YDYBZB Ear Pads Replacement. One pair covers a long list of Sony ZX/WH-CH/V-series and JBL Tune models.
• Best for the Sony studio line → Duyfioa Replacement Ear Pads. MDR-7506, MDR-V6, MDR-V7 and MDR-CD900ST only.

• Best if you just want the cushions → YDYBZB Ear Pads Replacement. Pads only, straightforward swap onto the models listed.
• Best for a thicker, non-pressing feel → Duyfioa Replacement Ear Pads. Added thickness is an explicit design point.
• Best for noise isolation through a conforming seal → YDYBZB Ear Pads Replacement. The firmer memory foam is pitched at blocking your environment while keeping the beat intact.

I would buy YDYBZB Ear Pads Replacement for most people, simply because most people own the headphones it fits — ZX110, ZX110NC, WH-CH500/510/520, V150/V250 or a JBL Tune. The memory foam seal and the clamping-pressure relief are the two things that actually change how a cheap-ish headphone feels after an hour, and the compatibility list means you are unlikely to order the wrong thing. That said, if you own a Sony MDR-7506, MDR-V6, MDR-V7 or MDR-CD900ST, I would not touch YDYBZB — Duyfioa is the right call there, and the included install tools plus the 1-year warranty make it the more complete repair kit. Match the pad to the headphone first; everything else is secondary.
FAQ
Duyfioa. It is built specifically for that model family, matches the original size, adds thickness and includes an opening pick and triangle opener for installation. YDYBZB does not list the 7506 as compatible.
Essentially yes. Both use protein/faux leather over memory foam, and both come in black. The difference is shape and fit, not material class — Duyfioa emphasizes added thickness, YDYBZB emphasizes a firmer foam for isolation.
Yes — I deliberately do not quote prices here, since they move around. Use the "Check latest price on Amazon" button on this page to see the current figure for whichever pad matches your headphones.
