If you want one set of foam pads that reshapes how a pair of Koss Porta Pro-family headphones sounds, choose Voarmaks Great Size Over; if you need to revive a worn-out pair of Bose QuietComfort 45 or QC SE with soft, skin-friendly cushions, choose GEVO Replacement Ear Pads. These two products share almost nothing except the word "ear pads" — one is a sound-tuning accessory for budget on-ear Koss models, the other is a straight comfort-and-fit replacement for a premium noise-cancelling headphone.
• Voarmaks Great Size Over — biggest strength: memory foam pads designed around the G-Cush shape, with no foam sitting between the driver and your ear, which the brand says produces a clear, bright balance on bass-heavy Porta Pro drivers.
• Voarmaks Great Size Over — biggest trade-off: it is a niche fit. It is built for Koss models like the KPH30i, KSC75 and Porta Pro, and the brand notes the KSC35 needs a separate portable headband to work with this style of pad.
• GEVO Replacement Ear Pads — biggest strength: a drop-in replacement for Bose QC45 and QC SE, using protein leather over memory foam with a stated noise-isolation goal and a skin-friendly, breathable feel for long listening.
• GEVO Replacement Ear Pads — biggest trade-off: it only fits Bose QuietComfort 45 and QuietComfort SE, so it is useless if you own anything else, and you must confirm your model before buying.
• Who each pick is for: Voarmaks for Koss Porta Pro-family owners chasing a different tuning; GEVO for Bose QC45/QC SE owners whose original cushions are flat, cracked or uncomfortable.
This pad exists because of a specific modding habit. According to the product information, audiophiles on forums started pairing G-Cush foam with the KPH30i, and Voarmaks built a compatible pad line for the Porta Pro family around that idea. The result is a set of black memory foam pads, 4.09 x 4.09 x 1.42 inches, weighing 21.8 g, made for the Koss KPH30i, KSC75 and Porta Pro.
The design detail that matters is the cut. The G-Cush shape leaves no foam between the driver and your ear, and the driver sits almost exactly inside the pre-cut hole. That geometry is why the brand describes a distinctive sound rather than just a comfort upgrade. Porta Pro drivers lean bassy by nature, and Voarmaks says these foams balance that with a clear, bright character that stops short of sounding sharp. In my opinion that is the real pitch here: it is a tuning experiment you can run in minutes, not a repair part.
Buy it if you own a Koss Porta Pro, KPH30i or KSC75 and you are curious how a different foam shape changes the signature — the brand even frames the whole line as a way to explore sound like an acoustic engineer, with S-Cush, L-Cush and G-Cush variants. Skip it if your headphones are not on that compatibility list, and note the KSC35 caveat: it needs a portable headband to use pads like these. If you want a simple like-for-like refresh of an untouched headphone, this is not that product.
GEVO's pads solve a much more common problem: the cushions on a well-used Bose QuietComfort 45 or QuietComfort SE have gone flat, flaky or clammy. The set is black, built from protein leather over memory foam, and sized 3.08 x 0.7 x 3.85 inches. Compatibility is narrow and stated plainly — QC45 and QC SE only — and GEVO asks you to confirm your headset model before ordering.
Where it aims to earn its place is long-session comfort. The brand describes a skin-friendly, feather-soft, breathable surface with soft memory foam inside, and says the pads conform to your ears to help isolate noise while keeping the sound quality intact. That combination is exactly what a commuter or a work-from-home caller wants: something that disappears on your head during a long call or an album run, rather than something that adds pressure after an hour.
I would point you here if you own QC45 or QC SE and your originals are visibly worn. Installation is described as easy — a straight swap rather than a project. Skip it if you own any other headphone, including other Bose models, because the fit is specific. And if you are chasing a sound change rather than a comfort refresh, this pad is not marketed that way at all; it is designed to preserve the tuning you already have. GEVO backs it with a one-year manufacturer warranty.
• Best for Koss Porta Pro, KPH30i or KSC75 owners → Voarmaks Great Size Over. It is the only one of the two that fits those models.
• Best for Bose QC45 or QC SE owners → GEVO Replacement Ear Pads. Voarmaks pads will not fit a Bose headphone.
• Best for changing how your headphones sound → Voarmaks Great Size Over. The no-foam-in-front-of-the-driver G-Cush geometry is the whole point of the design.
• Best for restoring comfort on a premium noise-cancelling headphone → GEVO Replacement Ear Pads. Protein leather plus memory foam, pitched at long calls and long listening.
• Best for a quick, low-effort swap → GEVO Replacement Ear Pads. GEVO describes installation as effortless; the Voarmaks route is more of a tuning exercise.
• Best for tinkerers → Voarmaks Great Size Over. The brand explicitly frames the S/L/G-Cush range as a way to explore different foam shapes, thicknesses and materials.
• Best for buyers who want a stated warranty → GEVO Replacement Ear Pads. GEVO lists a one-year manufacturer warranty; Voarmaks simply lists warranty as available.
• Best for anyone unsure about price → check the current price on Amazon for both. They sit in different product categories, so comparing figures side by side will not tell you much.
If I owned a Bose QuietComfort 45 or QC SE with tired cushions, I would buy the GEVO Replacement Ear Pads. The job is clear — bring back soft, breathable, conforming comfort without disturbing the sound — and protein leather over memory foam with a one-year warranty is the sensible answer.
If I owned a Koss Porta Pro or KPH30i, I would buy the Voarmaks Great Size Over instead, because nothing about the GEVO pad applies to that headphone. In my opinion the Voarmaks set is the more interesting purchase of the two: it is a cheap way to hear what a different foam shape does to a bassy driver. Different headphones, different problems — pick by what is on your desk, not by which pad sounds more impressive on paper.
FAQ
can you sleep with over ear headphones
how to wear over ear headphones
Put them on with the headband over the crown of your head and the pads sitting flat against your ears or around them, depending on the model. The GEVO pads are designed to conform to your ears so they can help isolate noise; the Voarmaks pads sit on the Koss driver with the driver positioned in the pre-cut hole.
how to wear over ear headphones properly
The pad should seal or sit evenly on both sides, with no gaps and no pressure hotspots. GEVO states its QC45/QC SE cushions conform to the ear to isolate noise and preserve sound quality, so even placement matters. On the Voarmaks pads, correct seating means the driver lines up with the cut hole, since there is no foam between driver and ear.
how should over ear headphones fit
Snug enough to stay put, loose enough to wear for hours. GEVO describes its pads as breathable and soft enough for long calls and listening sessions, which is the fit to aim for. The Voarmaks pads are thinner-profile foam at 1.42 inches deep, so expect a lighter, more open feel rather than a deep seal.
