How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want replacement pads that revive a whole family of Bose QuietComfort and around-ear models, choose Cypher.V Headphones Replacement Ear; if you need fresh cushions built specifically for the Skullcandy Crusher ANC 2, choose SINOWO Replacement Earpads.
• Cypher.V Headphones Replacement Ear — biggest strength: one pair of protein-leather, memory-foam cushions that fits a wide spread of Bose over-ear headphones, from the QC15 up through the QC35 II, plus AE2, SoundTrue and SoundLink models.
• Cypher.V Headphones Replacement Ear — biggest trade-off: because it's built as a cross-compatible fit for many Bose shapes, it isn't tailored to any single headphone the way a model-specific pad is, and it only really suits that Bose family.
• SINOWO Replacement Earpads — biggest strength: purpose-built for one headphone, the Skullcandy Crusher ANC 2, with high-density memory foam and a noise-isolating design that aims to sit "closer to the original."
• SINOWO Replacement Earpads — biggest trade-off: the narrow compatibility cuts both ways — if your headphones aren't the Crusher ANC 2, these simply won't work, and the cushion set is one pair, nothing more.
• Who each is for: Cypher.V is for the Bose owner refreshing tired cushions across several QC models; SINOWO is for the Crusher ANC 2 owner who wants a like-for-like replacement.
The Cypher.V set is, at heart, a compatibility play. One pair of black cushions is engineered to slot onto a long list of Bose over-ear headphones: QuietComfort 15, 25, 35 and 35 II, along with AE2, AE2i, AE2w, SoundTrue and SoundLink around-ear models. If you own more than one pair of these, or you've upgraded from an older QC to a newer one, that shared fit matters — you're not hunting for a different pad every time you change headphones.
The materials are the part most people care about day to day. Protein leather on the outside, elastic memory foam inside, shaped with an ergonomic curve so the cushion sits softly against the ear rather than clamping it. The memory foam is the key spec here: it's the layer that lets the pad conform to the shape around your ear instead of pressing flat, and it's what the noise-cancelling seal depends on. A worn, flattened pad lets sound leak in and out; a foam cushion that springs back helps the headphone do the job it was designed for. Cypher.V also stresses that the pads are shaped to match the ear cups exactly, so they shouldn't work loose with normal use.
Who should buy it: anyone with a compatible Bose QC or around-ear model whose original pads have gone shiny, cracked or flattened, and who wants a single pair that covers several headphones in that family. Who should skip it: if you don't own a Bose headphone from the listed models, this isn't your pad — the fit is the whole point, and it won't transfer to another brand.
SINOWO Replacement Earpads: Who It's For
SINOWO takes the opposite approach: it makes one pad for one headphone, and it says so plainly. These cushions are built for the Skullcandy Crusher ANC 2 over-ear noise-cancelling wireless headphones, and the brand asks you to confirm your model before buying — a fair warning, because there's no cross-compatibility here at all.
The construction is protein leather over memory foam, but SINOWO leans harder on the foam spec, calling it high-density. That's the meaningful detail. Denser foam tends to hold its shape longer and resist the slow flattening that plagues cheap pads, and it also presses more evenly around the ear, which is what the brand is pointing at when it talks about blocking outside sound and keeping things quiet. Combined with the ergonomic shape and the smooth, stretchable surface, the goal is a cushion that protects your ears from hard friction over long sessions rather than digging in.
The design brief is "closer to the original" — these are meant to feel like the pads your Crusher ANC 2 shipped with, not an upgrade or a re-style. Installation follows the usual routine: pull the old pads, fit the new ones, a few minutes of work, and the brand notes they shouldn't fall off easily once seated. Each set is one pair of pads. Dimensions come in at roughly 4.01 by 3.45 by 0.71 inches, so these are a compact, standard-thickness cushion. SINOWO backs them with a 180-day warranty.
Who should buy it: the Crusher ANC 2 owner whose stock pads have worn thin, gone flaky, or lost their seal, and who wants a straightforward replacement that behaves like the originals. Who should skip it: everyone else. If your headphones aren't the Crusher ANC 2, there's no reason to consider this set.
• Own a Bose QuietComfort 15, 25, 35 or 35 II → Cypher.V Headphones Replacement Ear. It's made for that family.
• Own a Skullcandy Crusher ANC 2 → SINOWO Replacement Earpads. It's the only one of the two that fits.
• Own several Bose around-ear models → Cypher.V. One pair covers QC15, QC25, QC35, QC35 II, AE2, AE2i, AE2w, SoundTrue and SoundLink.
• Want the densest foam for noise isolation → SINOWO. Its high-density memory foam is the headline spec.
• Want the widest compatibility → Cypher.V. A long compatible-model list versus a single model.
• Longer coverage window → Cypher.V. A one-year warranty against SINOWO's 180 days.
• Want a pad tuned to one headphone's original feel → SINOWO. Built specifically for the Crusher ANC 2.
• Not sure which you need → match the pad to your headphone model first. Compatibility decides this one before anything else.
In my opinion, the deciding factor here isn't the foam or the leather — both sets use protein leather over memory foam — it's which headphone is sitting on your desk. If you own a Bose QC15, QC25, QC35 or 35 II, I'd buy the Cypher.V Headphones Replacement Ear: it fits that broad Bose family, uses elastic memory foam for a soft ergonomic seal, and carries a one-year warranty. If you own the Skullcandy Crusher ANC 2, I'd buy the SINOWO Replacement Earpads, because it's the one built for your exact model and its high-density foam is aimed squarely at noise isolation. Match the pad to the headphone and you can't really go wrong.
can you sleep with over ear headphones
You can, but it's not ideal with either of these sets. Both use memory foam and protein leather cushions that are designed for listening sessions, not for lying on a pillow — pressing a pad against a surface for hours flattens foam and can crack the leather over time.
how to wear over ear headphones
Slide them on so each cushion sits around your ear, not on top of it. The memory foam should seal against the skin around your ear — that seal is what lets the noise-isolating design do its work, and it applies to both the Cypher.V pads and the SINOWO pads.
how should over ear headphones fit
Snug but not tight. The headband should hold the pads gently against your head while the memory foam compresses just enough to seal, with no hard clamping on the ears. If the pads feel like they're pressing flat or slipping, they may not be seated correctly on the ear cups.
how to wear over ear headphones properly
Fit matters more than angle: cups centered over the ears, cushion fully surrounding each ear, headband resting evenly on the crown. Both replacement sets are shaped to match their intended ear cups and are made to stay put once installed, so a proper fit should hold through normal use.
