• YDYBZB Ear Pads Replacement — biggest strength: protein leather over memory foam, with a compatibility list that covers a long run of Sony MDR-ZX and WH-CH models plus several JBL Tune sets. That breadth is the whole point of this pad.
• YDYBZB Ear Pads Replacement — biggest trade-off: it is a straightforward replacement pad with no cooling layer and no installation tools in the box. You get one pair of earpads and your own hands.
• SoloWIT Cooling-Gel Replacement Ear — biggest strength: a cooling-gel layer sits under a breathable ice silk top fabric, and the kit ships with scrims, a plastic stick and a guide to make the swap quicker.
• SoloWIT Cooling-Gel Replacement Ear — biggest trade-off: it only fits Bose models — QC2, QC15, QC25, QC35 I and II, the AE2 family, SoundTrue Around-Ear and SoundLink Around-Ear. If your headphones are not on that list, it is useless to you.
• Who YDYBZB is for: owners of Sony MDR-ZX110/ZX110NC, ZX310, ZX330BT, WH-CH500/CH510/CH520, V150/V250, or JBL Tune 510BT/500BT/450BT/660NC/600BTNC who want a simple, low-fuss pad swap.
• Who SoloWIT is for: Bose QuietComfort and SoundLink owners who wear their headphones for hours and want their ears to stay cool while they do it.
The YDYBZB Ear Pads Replacement is a protein leather and memory foam cushion built around compatibility. The list is genuinely long: Sony MDR-ZX110, ZX110NC, ZX310, ZX330BT, WH-CH500, CH510, CH520, V150 and V250, plus JBL Tune 510BT, 500BT, 450BT, 660NC and 600BTNC. If you own any of those, you are exactly who this pad was made for.
What it does best is the basics. The protein leather is described as professional-grade and designed to resist cracking over long-term use, and the memory foam is firmer than a soft pillow pad — which matters, because a firmer foam is what creates the ear-conforming seal. That seal is what isolates your ears from the room and keeps the low end of your music from leaking away. The pads are also described as high-elasticity and easy to install, and they are pitched at relieving the clamping pressure that builds up during long listening sessions. At roughly 2.76 x 2.76 x 0.39 inches per pad and about 4.54 grams, these are light, thin on-ear cushions — the shape tells you they are meant for the compact Sony and JBL models listed, not for big over-ear cups.
SoloWIT Cooling-Gel Replacement Ear: Who It's For
The SoloWIT Cooling-Gel Replacement Ear is a different animal entirely. It is made for Bose over-ear headphones — QC2, QC15, QC25, QC35 I, QC35 II, the AE2, AE2i and AE2w, SoundTrue Around-Ear and SoundTrue Around-Ear II, and SoundLink Around-Ear and SoundLink Around-Ear II. That is a deep compatibility list, but it is a Bose-only list.
Its defining feature is the cooling layer. A soft cooling gel sits under the top fabric, which is a breathable ice silk. The idea is simple: the gel absorbs sweat on warm days and keeps your ears cooler after a long stretch of use. If you have ever pulled off a pair of over-ear headphones in summer and felt that damp, hot ring around your ears, that is precisely the problem this pad is designed to solve.
The second thing SoloWIT gets right is the install kit. Alongside the earpads you get a pair of scrims, a user guide and a plastic stick that makes prying the old pads off and seating the new ones faster — the brand estimates around five minutes. The padding itself is memory foam, and the pads come in an orange colorway, which is a visible style choice rather than a stealthy black replacement.
Who should buy it: QC35 or QC35 II owners, or anyone with the older Bose models on that list, who wears their headphones for hours and wants a cooler feel. Who should skip it: anyone whose headphones are not Bose, and anyone who wants a plain black pad, since these are orange. Note also that the warranty description is listed as "No," so factor that into your expectations.
• Best for Sony MDR-ZX or WH-CH owners → YDYBZB Ear Pads Replacement. The ZX110, ZX110NC, ZX310, ZX330BT and WH-CH500/CH510/CH520 are all named.
• Best for Bose QuietComfort 35 / 35 II owners → SoloWIT Cooling-Gel Replacement Ear. It is built specifically for that family.
• Best for hot ears and long summer sessions → SoloWIT Cooling-Gel Replacement Ear. The cooling gel and ice silk fabric are the only cooling features in this comparison.
• Best for a no-tools, quick swap → SoloWIT Cooling-Gel Replacement Ear. The included plastic stick, scrims and guide are designed to make installation a five-minute job.
• Best for a simple black replacement pad → YDYBZB Ear Pads Replacement. SoloWIT's option is orange.
• Best for sound isolation through a firm foam seal → YDYBZB Ear Pads Replacement. The firmer memory foam is what creates the ear-conforming fit that blocks outside noise.
• Best for wide brand coverage across Sony and JBL → YDYBZB Ear Pads Replacement. SoloWIT is deeper within one brand; YDYBZB is wider across two.
One thing neither product changes: they are earpads, not electronics. Buying either will not upgrade your headphone's drivers, Bluetooth version or noise cancelling. What they change is fit, comfort, seal and the way your headphones feel after hour three.
My Verdict
If I owned a Bose QC35 or QC35 II, I would buy the SoloWIT Cooling-Gel Replacement Ear. The cooling gel and ice silk layer address the single most annoying thing about long over-ear sessions, and the included install kit lowers the barrier to actually doing the swap. If I owned any of the Sony or JBL models on the YDYBZB list, I would buy the YDYBZB Ear Pads Replacement instead — it is the one that fits, and the firmer memory foam is the right call for restoring a proper seal. My honest read: match the pad to your headphone model first, then decide on cooling. Buying the wrong fit helps nobody.
No. The YDYBZB compatibility list covers Sony MDR-ZX and WH-CH models plus several JBL Tune sets. Bose headphones are not on it. For QC35 or QC35 II, you want the SoloWIT pads.
No. SoloWIT lists only Bose models — QC2, QC15, QC25, QC35 I and II, AE2/AE2i/AE2w, SoundTrue Around-Ear and SoundLink Around-Ear. If your headphones are Sony or JBL, the YDYBZB pads are the correct choice.
Based on the design, yes — the SoloWIT pad adds a cooling-gel layer under breathable ice silk fabric specifically to absorb sweat and reduce heat build-up. The YDYBZB pad has no gel layer; its focus is a firm memory foam seal for isolation and a crack-resistant leather surface.
Check your headphone model against the two compatibility lists before anything else. If you are on a Sony or JBL model, take the YDYBZB. If you are on a Bose model and want cooler ears, take the SoloWIT. Then check the current price on Amazon using the button on this page before you commit.
