If you want a plush, longer-lasting replacement pad for your Bose QuietComfort 15 (and its siblings), choose WC PadZ QC15; if you need fresh velour cushions for a Beyerdynamic DT770/DT880/DT990-style headset, choose YunYiYi MMX300.
• WC PadZ QC15 — biggest strength: thicker memory foam in a faux-leather (PU) cover, with inside seams reinforced by both extra stitching and glue to fight the splitting that kills stock pads.
• WC PadZ QC15 — biggest trade-off: it is Bose-specific. It is built for QuietComfort 15 / QC25 / QC2 / AE2 / AE2i / AE2w / SoundTrue / SoundLink over-ears and will not fit other brands.
• YunYiYi MMX300 — biggest strength: a skin-friendly velour-and-memory-foam pad that resists sweat and peeling, aimed at the Beyerdynamic DT770 family and its DT880/DT990/HS200/HS400 relatives.
• YunYiYi MMX300 — biggest trade-off: it is a Beyerdynamic-fit product only, and the headband/earpad listing covers a wide model list, so you must match your exact headphone before ordering.
• Who each pick is for: WC PadZ QC15 if you own Bose over-ears and want comfort plus durability; YunYiYi MMX300 if you run a Beyerdynamic DT-series headset and prefer a breathable velour feel.
The WC PadZ QC15 is a direct replacement kit for worn-out Bose ear cushions. The pitch is simple: your original pads flatten, crack, and split at the seams, and when they do, the seal around your ear breaks down. That seal is doing a lot of the work — it is what helps block outside noise and keeps your music sounding the way it should. WC's answer is a thicker memory-foam pad wrapped in faux leather that is meant to conform to your ear and stay thick for longer.
Two details stand out to me. First, the seam construction: the inside seams use stitching reinforced with glue, which is aimed squarely at the split-seam failure that plagues factory pads. Second, fit. This kit is confirmed for the Bose QuietComfort 15, QuietComfort 2, QC25, AE2, AE2i, AE2w, SoundTrue, and SoundLink over-ear models — nothing else. The package includes a step-by-step guide and needs no special tools, so a first-timer can swap pads in one sitting. WC also backs it with a 365-day full warranty.
YunYiYi MMX300: Who It's For
The YunYiYi MMX300 is a different animal. It targets the Beyerdynamic ecosystem — DT770S, DT770M, DT770 Pro, DT770 Pro HT, DT 790, DT797, DT880, DT880 Pro, DT880 Pro HT, DT990, DT990 Pro, HS200, and HS400 headsets, plus Custom One Pro Plus. The pad itself is memory foam wrapped in a soft velour (velvet) mesh fabric, which is the classic choice for long listening sessions because it breathes instead of trapping heat.
That material choice matters. The listing calls out sweat resistance and resistance to peeling, and notes comfort on work calls — the kind of thing that matters if you wear a headset for hours at a desk rather than in short bursts. YunYiYi also claims the replacement fabric and foam are made with enhanced soundproofing, so you get a refreshed seal and, in their framing, improved sound versus tired old cushions.
Installation is tool-free and described as a minutes-long job. One thing to watch: the listing bundles earpads and a headband, and the stated pad dimensions are a 100 mm outer diameter, 60 mm inner diameter, and 25 mm thickness. If you are replacing just one part, confirm what your order includes. The warranty is a no-risk promise — contact them for a free replacement or refund on any quality issue.
Buy it if you run a Beyerdynamic DT770/DT880/DT990-family headset and want breathable velour comfort. Skip it if your headphones are Bose or another brand entirely.
• Best for Bose owners → WC PadZ QC15. It is the only one of the two that fits QuietComfort 15, QC25, QC2, AE2, and the rest of that Bose list.
• Best for Beyerdynamic owners → YunYiYi MMX300. DT770, DT880, DT990, HS200, HS400 and friends are exactly what it is built for.
• Best for hot, long sessions → YunYiYi MMX300. Velour mesh breathes and resists sweat; that is the whole point of the material.
• Best for sealing out noise → WC PadZ QC15. The thicker memory foam and faux-leather cover are aimed at conforming to your ear and blocking outside sound.
• Best against seam failure → WC PadZ QC15. Glue-reinforced, extra-stitched inside seams are a direct answer to the splitting that ruins stock Bose pads.
• Best tool-free quick swap → both. Neither needs special tools, and both are described as minutes-long installs.
• Best warranty framing → split decision. WC offers a 365-day full warranty; YunYiYi offers free replacement or refund on quality issues.
• Best if you are unsure of your model → check first. Both are model-locked. Matching your headphone to the compatibility list is the single most important step.
In my opinion, the right buy depends entirely on which headphone sits on your desk, not on which pad is "better." If you own a Bose QuietComfort 15 or any of its listed siblings, I would buy the WC PadZ QC15 — the reinforced seams and thicker memory foam address the two things that actually go wrong with Bose pads. If you own a Beyerdynamic DT770/DT880/DT990-style headset, I would buy the YunYiYi MMX300, because velour is the material those headphones were designed around and the sweat/peel resistance is a real everyday win. There is no crossover here: pick the one that matches your model.
FAQ
No. The WC PadZ QC15 is confirmed only for Bose over-ear models — QuietComfort 15, QC25, QC2, AE2, AE2i, AE2w, SoundTrue, and SoundLink. Beyerdynamic owners should look at the YunYiYi MMX300 instead.
No. The YunYiYi MMX300 is built for the Beyerdynamic DT770/DT880/DT990 family and related models like the HS200 and HS400. It is not made for Bose headphones.
It depends on your preference. The YunYiYi MMX300 uses breathable velour that resists sweat, which suits hot, extended sessions. The WC PadZ QC15 uses thicker memory foam with a faux-leather cover for a snug, noise-blocking seal. In my opinion, velour feels cooler; faux leather feels more isolating.
Neither does. WC includes a step-by-step guide and says no special tools are needed; YunYiYi says the whole process takes minutes and needs no tools. Just confirm your exact headphone model against the compatibility list before ordering, and check the current price on Amazon since it can change.
