• D & K Exclusives' biggest strength: ten soft foam mini-cushions that stretch onto a huge range of small earbuds, headsets and walkie-talkie earpieces, so you can refresh several devices at once.
• D & K Exclusives' biggest trade-off: these are 20mm foam covers, not full earcups — they will not fit over-ear or large on-ear headphones, and foam wears out faster than leather.
• Duyfioa's biggest strength: memory foam plus protein leather pads shaped to match the originals on Sony MDR-7506, MDR-V6, MDR-V7 and MDR-CD900ST, with tools included to snap them on.
• Duyfioa's biggest trade-off: it only fits those Sony models — buy it for anything else and it simply won't work.
• Who each pick is for: D & K Exclusives for anyone keeping a drawer of small earbuds, Bluetooth buds and radio earpieces alive; Duyfioa for Sony studio-headphone owners whose original pads have flattened or peeled.
This is a maintenance product, not a glamorous one. You get a 10-pack of black 20mm foam cushions made from high-elasticity sponge. They're built to slip over the nozzle or earpiece of small in-ear gear — the kind of thing that quietly improves comfort on earbuds you already own rather than replacing the headphones themselves.
The design logic is sound. Foam that sits against your inner ear spreads pressure instead of concentrating it, which is why D & K describes less soreness over long listening sessions. The same material absorbs vibration and limits sound leakage, so bass tends to feel a little fuller and the fit a little more secure. The sheet also notes the foam is moisture- and sweat-resistant and shaped to hold its softness over time, which matters if you wear buds while walking, commuting or working out. Compatibility is deliberately broad: Apple EarPods, AirPods, MX500-style buds, wired and wireless earbuds, Bluetooth sets, headsets and walkie-talkie earpieces are all listed.
Buy it if you own several small earbuds or radio earpieces and want one inexpensive pack that covers hygiene refreshes, spare sets and replacements for lost tips. Skip it if your problem is a pair of over-ear headphones with crumbling pads — foam minis are the wrong shape and the wrong scale for that job.
Duyfioa's pads are a targeted repair part. They're made for Sony's MDR-7506, MDR-V6, MDR-V7 and MDR-CD900ST — a family of studio and monitoring headphones that thousands of people still use daily, often with pads that have gone flat, flaky or cracked. The construction is memory foam wrapped in protein (faux) leather, with the sheet noting added thickness so the pad doesn't press on your ears.
Fit is the selling point. Duyfioa states the pads are the same size as the originals, so they seat into the existing earcup grooves rather than being stretched over them. The listing walks through a four-step install: peel off the old pads, wipe dust from the earcup base, align the left and right pads into the grooves, then press the edges down to remove wrinkles and gaps. Two small tools — an opening pick and a triangle opener — come in the box to help with that. You get a two-count set, a stated one-year manufacturer warranty, and a spare-part availability window of two years.
Buy it if you own one of those Sony models and want to bring a tired pair back to comfortable, presentable condition without hunting for a new headphone. Skip it if your headphones are any other brand or model — Duyfioa is explicit that you should confirm your model first, and there's no universal fit here.
• Best for tiny in-ear earbuds → D & K Exclusives Ear Cushions. 20mm foam covers are sized for buds, not earcups.
• Best for Sony MDR-7506 / V6 / V7 / CD900ST → Duyfioa Replacement Ear Pads. Purpose-built, same size as the originals.
• Best for walkie-talkies and headset earpieces → D & K Exclusives. Their compatibility list explicitly includes radio and headset gear.
• Best for over-ear comfort and seal → Duyfioa. Memory foam plus protein leather gives a full cushion that sits around the ear rather than inside it.
• Best for refreshing several devices at once → D & K Exclusives. A 10-pack goes a long way across a drawer of earbuds.
• Best for a single, precise repair → Duyfioa. Two pads, two tools, and a documented four-step install.
• Best for sweat and workout use → D & K Exclusives. The foam is described as moisture- and sweat-resistant and gentle on skin.
• Best for long-term durability → Duyfioa. Faux leather over memory foam generally outlasts bare sponge, though the sheet itself only specifies a one-year warranty.
My Verdict
Only the Duyfioa Replacement Ear Pads. The sheet lists MDR-7506, MDR-V6, MDR-V7 and MDR-CD900ST as the compatible models, and Duyfioa advises confirming your headphone model before buying. The D & K Exclusives foam cushions are 20mm minis and aren't made for over-ear headphones.
They're soft foam covers — 20mm, high-elasticity sponge that slips over small earpieces. They add cushioning, reduce leakage and improve hygiene on earbuds, headsets and walkie-talkies, but they don't replace a full earcup.
Not hard, according to the instructions. Duyfioa describes four steps — peel off the old pads, clean the earcup base, align the new pads into the grooves, then press the edges flat. An opening pick and a triangle opener are included to help.
They cost very different amounts of effort for very different jobs, so compare them on fit rather than anything else. Check the current price on Amazon for each, then buy the one that matches your headphones — the D & K pack if you're refreshing small earbuds, the Duyfioa set if you're repairing a Sony studio pair.
