If you want a breathable fabric pad that fits a wide range of Bose QuietComfort and SoundLink/AE2 headphones, choose Krone Kalpasmos Earpads; if you need a thicker memory-foam replacement built specifically for Beats Studio 2 and Studio 3 with a strong adhesive backing, choose GEVO GVOEARS Replacement Ear.
These two pads live in different worlds. One is a Bose-focused refresh with a soft cloth-and-leather face. The other is a Beats-focused rebuild with dense foam and glue. The right pick comes down to which headphones you actually own — and what bothers you about the pads you have now.
• Biggest strength (Krone Kalpasmos): A breathable fabric surface plus memory foam and a dust mat, in a fit that covers a long list of Bose models, including QC35, QC35 II, QC25, QC2, QC15, AE2, AE2i, AE2w and SoundTrue around-ear.
• Biggest trade-off (Krone Kalpasmos): It's a Bose-only part. If you own Beats, it simply won't fit, and the grey pattern finish is a style choice rather than a neutral black.
• Biggest strength (GEVO GVOEARS): High-density memory foam with more ear space, a protective inner seam, and an upgraded adhesive that the brand says holds tighter than the original, plus a spare adhesive pair in the box.
• Biggest trade-off (GEVO GVOEARS): It fits Beats Studio 2 and Studio 3 only, and installation leans on adhesive, so the prep and cure steps matter.
• Who each is for: Krone Kalpasmos for Bose QC/AE2 owners who want a softer, more breathable feel; GEVO GVOEARS for Beats Studio 2/3 owners who want a thicker foam rebuild that stays put.
The Krone Kalpasmos pads are aimed squarely at Bose owners. The compatibility list is broad: QC35, QC35 II, QC25, QC2, QC15, AE2, AE2i, AE2w and SoundTrue around-ear. If you're sitting on a pair of these and the cushions have gone flat or shiny, this is a direct swap rather than a gamble on a universal fit.
Installation is tool-light: the brand says it takes a few minutes and includes the necessary parts, and the hollow, buckle and sizing are stated to mirror the original cushions so sound isn't thrown off.
Who should skip it? Anyone with Beats, obviously — wrong mount entirely. Also skip it if you want a pure black look, or if you'd rather have dense protein-leather foam than a breathable cloth face. And if you're the type who waits until a pad is fully shredded, note the brand's own guidance: it suggests replacing cushions every seven to eight months for hygiene, and states they can be used for 180 days or more.
GEVO GVOEARS Replacement Ear: Who It's For
The GEVO GVOEARS pads are for Beats Studio 2 and Studio 3 owners — wired and wireless variants included (models like B0500 and B0501). That's a tighter net than the Bose option, and it means you shouldn't buy these hoping they'll stretch to something else.
The foam is the headline. It's high-density memory foam, and the brand's pitch is that it conforms to your ear while giving more internal space, which helps block outside noise and keeps pressure off. The cushion cover is protein leather, which the brand describes as soft, breathable and resistant to getting swampy on hot days. There's also an inner-seam stitch — a real design point, since the brand notes that after about a year of use, some earpads split along that inner loop and start leaking filler, which kills the noise isolation. Stitching it should hold up longer.
The adhesive is the other half of the story. The brand says the upgraded backing is more stable and tighter than the original and less likely to peel off, and the package includes a spare pair of adhesives. Extras in the box: one pair of pads, wipe pads, a crowbar for prying the old cushions off, and instructions. The headphone itself is not included.
Side-by-Side: Which Should You Choose?
• Best for Bose QC35 / QC25 / QC15 / AE2 owners → Krone Kalpasmos Earpads. The compatibility list covers these directly.
• Best for Beats Studio 2 / Studio 3 owners → GEVO GVOEARS Replacement Ear. Nothing else in this comparison fits those cups.
• Best for breathability and cooler wear → Krone Kalpasmos Earpads. The soft fabric face and dust mat are built around airflow and keeping the cup interior clean.
• Best for thicker, denser cushioning → GEVO GVOEARS Replacement Ear. High-density memory foam is the core of its design, with an emphasis on ear space.
• Best for a secure, low-lift fit → GEVO GVOEARS Replacement Ear. The upgraded adhesive plus a spare pair is aimed at pads that won't slide off.
• Best for a quick, tool-included install → Krone Kalpasmos Earpads. A few minutes, no glue, parts included.
• Best for long-term tear resistance → GEVO GVOEARS Replacement Ear. The inner-seam stitch targets the exact spot where pads tend to split.
• Best for a distinctive look → Krone Kalpasmos Earpads. Grey pattern leather instead of standard black, if you want your Bose to look a little different.
In my opinion, the deciding factor here isn't quality — it's the mount. These pads don't overlap, so buy the one that matches your headphones. If you own Bose QC or AE2-series cans, I'd take the Krone Kalpasmos Earpads: the breathable fabric face, memory foam and dust mat make it a smart daily-wear refresh, and the wide model coverage means fewer ordering mistakes. If you own Beats Studio 2 or Studio 3, I'd take the GEVO GVOEARS Replacement Ear — denser foam, a stitched inner seam and a spare adhesive set are the features that actually keep a Beats pad alive longer. Check the current price on Amazon before you commit, since that's the one variable neither sheet settles.
FAQ
They take a bit more care than a snap-on pad because they use adhesive. The brand includes wipe pads, a crowbar and instructions, and recommends cleaning old glue first and clamping the headphones on something thick for a few hours so the glue sets properly.
The Krone Kalpasmos pads lean on a breathable fabric face, which should feel less warm than a full leatherette cover. The GEVO GVOEARS pads use protein leather, which the brand describes as breathable, but the foam underneath is high-density, so expect a plusher, warmer feel.
Krone Kalpasmos suggests swapping cushions every seven to eight months for hygiene and states theirs can last 180 days or more. GEVO points to inner-seam splitting after roughly a year of use as the common failure — which is exactly what its stitched seam is designed to delay.
