How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to keep a pair of Koss Porta Pro, KPH30i or KSC75 alive with a memory foam over ear pad that reshapes their sound, choose Voarmaks Great Size Over; if you need to rescue a worn-out pair of Beats Studio 2 or Studio 3 with a ready-to-install memory foam cushion kit, choose GEVO GVOEARS Replacement Ear.
• Voarmaks Great Size Over — biggest strength: a G-Cush style memory foam pad shaped so there is no foam sitting between the driver and your ear, which the brand says gives a clear, bright balance to the naturally bassy Porta Pro driver.
• Voarmaks Great Size Over — biggest trade-off: it is a niche fit. It is built around Koss KPH30i, KSC75 and Porta Pro style headphones, and the brand even notes the KSC35 needs a portable headband before these pads will work.
• GEVO GVOEARS Replacement Ear — biggest strength: a complete memory foam over ear replacement kit for Beats Studio 2 and Studio 3, with strong adhesive, spare adhesive pairs, a wipe pad, a crowbar and printed instructions in the box.
• GEVO GVOEARS Replacement Ear — biggest trade-off: it is locked to Beats Studio models (B0500, B0501, Studio 3 wired and wireless). On anything else it simply will not fit.
• Pick Voarmaks if you are tweaking the sound of a Koss on-ear headphone and want a memory foam over ear pad with an acoustic purpose.
• Pick GEVO if your Beats Studio pads have flattened, split or started flaking and you want to restore comfort and sealing without buying new headphones.
The story behind this pad is the interesting part. According to the brand, audiophiles on forums had already been pairing G-Cush foams with the Koss KPH30i, and Voarmaks turned that experiment into a small family of compatible pads (G-Cush, L-Cush, S-Cush). This "Great Over Ear Pads" listing is the big one — a memory foam pad measuring roughly 4.09 x 4.09 x 1.42 inches and weighing 21.8 grams, in black.
What sets it apart is the geometry. The pre-cut hole is sized so the driver sits almost exactly inside it, with no foam blocking the space between the driver and your ear. That single design choice explains the sound the brand describes: the Porta Pro driver leans warm and bassy on its own, but with this pad the result is described as clearer and brighter without turning sharp. In other words, this is not just a comfort pad — it is a way to explore how pad shape, thickness and material change what you hear. If you like tinkering, that is genuinely fun.
Who should buy it? Owners of Koss KPH30i, KSC75 or Porta Pro headphones who find the stock sponge pads too thin, too scratchy or too leaky, and who want a roomier memory foam over ear feel plus a shift toward a brighter, more open presentation. Who should skip it? Anyone with Beats Studio 2 or Studio 3, anyone with a KSC35 who does not want to add a portable headband first, and anyone who wants a stock-sounding pad rather than a different sound. Also skip it if you expect a universal fit — this is a model-specific pad. And since the brand does list a warranty, it is worth checking the current price on Amazon before committing.
This is a repair kit disguised as a pair of ear pads, and I mean that as a compliment. The GEVO GVOEARS set is built for Beats Studio 2 (B0500, B0501) and Beats Studio 3, wired and wireless. The cushions use high-density memory foam wrapped in protein leather — soft, breathable, and shaped to give your ears more room while blocking outside noise. In a noisy commute or a shared office, that sealing is the whole point.
The durability angle is where the brand's thinking shows. GEVO says the inner seam is stitched to stop the pads splitting, because after about a year of use many ear cushions tear along that inner loop, the filler spills out, and both comfort and noise isolation collapse. That is a real failure mode on this style of headphone, and the stitched inseam is a direct answer to it. The adhesive on the back is described as upgraded and tighter than the original, and you get spare adhesive pairs in case you want a second attempt.
The package is unusually complete: one pair of pads, spare strong adhesive, a wipe pad to clean off the old glue, a crowbar for prying the old cushions off, and installation instructions. The brand suggests wiping the old adhesive with alcohol cotton first, using a butter knife or small flathead screwdriver if you have no crowbar, and then leaving the headphones clamped on a thick book or shoe box for a few hours so the glue sets properly. Note that the headphones themselves are not included.
Who should buy it? Anyone whose Beats Studio 2 or 3 pads have flattened, cracked or started peeling, and who wants the headphone back to a soft, well-sealed, comfortable state. Who should skip it? Anyone who does not own Beats Studio 2 or Studio 3 — the fit is specific, and these will not work on a Koss or on other Beats models. Also skip it if you would rather not do any hands-on installation, even though the kit is designed to make it straightforward. Warranty runs 180 days, and as always, check the current price on Amazon.
Side-by-Side: Which Should You Choose?
• Best for Koss Porta Pro / KPH30i / KSC75 owners → Voarmaks Great Size Over.
• Best for Beats Studio 2 or Studio 3 owners → GEVO GVOEARS Replacement Ear.
• Best for sound tuning, not just comfort → Voarmaks. The no-foam-in-front-of-the-driver design is an acoustic choice, not a cosmetic one.
• Best for restoring noise isolation on a worn headphone → GEVO. The high-density memory foam and protein leather are aimed at sealing and blocking external noise.
• Best for a complete install kit → GEVO, which includes adhesive, spare adhesive, a wipe pad, a crowbar and instructions.
• Best for a bigger, roomier over ear feel on a small headphone → Voarmaks, with its roughly 4.09-inch footprint and 1.42-inch depth.
• Best for long-term durability against seam splitting → GEVO, thanks to the stitched inner seam and thicker memory foam.
• Not sure which fits your headphones? Check your model number first. Koss models go Voarmaks, Beats Studio 2 and 3 go GEVO. There is no overlap.
If I owned Beats Studio 2 or Studio 3 headphones with tired pads, I would buy the GEVO GVOEARS Replacement Ear. It solves a specific, common problem — flattened, splitting cushions killing both comfort and noise isolation — and it hands you the tools and instructions to fix it in one go, with spare adhesive if the first attempt needs a second pass.
If I owned a Koss Porta Pro, KPH30i or KSC75 and wanted to hear what a proper memory foam over ear pad does to that sound, I would buy the Voarmaks Great Size Over. It is the more interesting product, but it only makes sense if you are in the Koss ecosystem and curious about tuning. Different jobs, no real overlap.
It is possible, but these two products are not designed for it. The Voarmaks Great Size Over pad is about 1.42 inches deep, and the GEVO pad is roughly 1.2 inches deep, so both add bulk that presses against a pillow. If sleeping is your goal, a flatter, lower-profile pad and a headphone that does not clamp hard will serve you better.
How to wear over ear headphones?
Snug but not tight. The pads should fully surround your ear with a light, even seal all the way around — that seal is what delivers the noise isolation the GEVO memory foam is built for. If you feel pressure points after ten minutes, or the pads barely touch your head, the fit is off and you should adjust the headband or reconsider the pad size.
No, and this is the most important thing on the page. Voarmaks is made for Koss KPH30i, KSC75 and Porta Pro, and the brand notes the KSC35 needs a portable headband first. GEVO is made for Beats Studio 2 (B0500, B0501) and Beats Studio 3, wired and wireless. Check your exact model before ordering.
