How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to restore the noise cancelling you already paid for on your Bose over-ear headphones, choose Krone Kalpasmos Professional Replacement Bose; if you need a soft headband you can actually sleep in, choose Perytong Sleep Headphones. These two products solve completely different problems, and the fastest way to waste money is to buy one when you needed the other.
• Krone Kalpasmos Professional Replacement Bose — biggest strength: protein leather over high-density memory foam that is built to restore the sound and noise cancelling behaviour of Bose QuietComfort and AE2-series headphones rather than change it.
• Krone Kalpasmos Professional Replacement Bose — biggest trade-off: it is a spare part, not a product. If you do not own a compatible Bose headphone, it does nothing for you at all.
• Perytong Sleep Headphones — biggest strength: an ultra-thin driver sits in the middle of a stretchy spandex headband, so nothing presses into your ear when you lie on your side, and the band doubles as a light-blocking eye mask.
• Perytong Sleep Headphones — biggest trade-off: there is no active noise cancelling here. The listing states noise control as "None" — any quieting comes from fabric over your ears, not from electronics.
• Who each pick is for: Krone Kalpasmos for someone whose Bose pads are flaking, cracked or flat; Perytong for a side sleeper, jogger or traveller who wants sound without anything shoved into their ear canal.
This is a maintenance purchase, and that is the whole point. Krone Kalpasmos makes replacement ear cushions for a long list of Bose models: QuietComfort 35 (both generations), QC25, QC2, QC15, AE2, AE2i, AE2w, SoundTrue around-ear and SoundLink around-ear. The pads are blue, measure roughly 3.82 by 3.07 by 0.75 inches, and weigh about 20 grams for the set. The material is protein leather over a high-density memory foam core, with a dust-proof mesh behind it to keep the inside of the cup clean.
What I like about the design brief here is that it is deliberately conservative. The manufacturer states the pads were tested across multiple Bose models specifically to keep the original sound signature and to maintain the headphones' noise cancelling behaviour. That matters, because the seal between pad and skull is what ANC depends on. A flat or torn cushion leaks, and leaked bass plus leaked noise is exactly why old Bose headphones start sounding thin. The memory foam is shaped to wrap the ear closely, which is the mechanism doing the work. The leather is described as anti-scratch and resistant to sweat, oil and cosmetics, with a stated lifespan of 12 months or more, and the brand backs it with a three-year manufacturer warranty.
Perytong Sleep Headphones: Who It's For
Perytong takes the opposite approach: instead of sealing around your ear, it removes the ear from the equation. The drivers are ultra-thin and sit in the middle of a spandex headband, so the fabric — not a plastic cup — touches your head. For anyone who sleeps on their side, that is the entire argument. The band is described as not pressing against the ear, not slipping off the way earplugs do, and not causing pressure pain overnight.
The spec list is more capable than the price bracket implies. Bluetooth 5.4 with a stated range of up to 33 feet (10 metres), dynamic drivers covering 20 Hz to 20,000 Hz, a high-fidelity chip for stable sound during movement, and hands-free calling plus track control without touching your phone. Battery is listed at 10 hours of playtime with a 2-hour recharge, which lines up with a full night's sleep. It is compatible with iOS, Android and Windows devices, and the power draw is low enough that the listing claims no electrical hiss as the battery drains — a small detail that matters a lot at 3 a.m.
It also pulls double duty. The band structure is shaped to sit around the ears and nose bridge and blocks most light, so it works as a sleep mask. Stretch fabric means it fits a wide range of head sizes. It is positioned for running, jogging, yoga, insomnia, air travel and meditation.
Be clear-eyed about the trade-off: noise control is listed as "None". If you want to mute a plane cabin or a snoring partner, this softens sound through fabric coverage — it does not cancel it. Skip it if you need real ANC, and skip it if you want critical listening; a headband driver is not a substitute for a proper over-ear. Buy it if comfort while lying down is the priority, or if you want one wearable for sleep, workouts and travel.
Side-by-Side: Which Should You Choose?
• Best for restoring noise cancelling on existing Bose headphones → Krone Kalpasmos Professional Replacement Bose. The pads are explicitly built to preserve ANC and sound rather than alter them.
• Best for genuine active noise cancelling → Krone Kalpasmos, but only because it keeps your Bose working. Perytong lists noise control as none.
• Best for workouts, jogging and yoga → Perytong Sleep Headphones. Stretch spandex, 10-hour battery, hands-free calls and no cable.
• Best for long-term ownership cost → Krone Kalpasmos Professional Replacement Bose. A set of pads extends a headphone you already own, with a stated 12-month-plus leather life and a three-year manufacturer warranty.
• Best for gifting → Perytong Sleep Headphones. It ships with gift packaging and is pitched for birthdays, holidays and stocking stuffers.
• Best for travellers who hate earplugs → Perytong Sleep Headphones. Bluetooth 5.4, 33-foot range, and it doubles as a light-blocking eye mask.
• Best for people who own no Bose headphones → Perytong Sleep Headphones. The Krone Kalpasmos pads are useless without a compatible model.
If your Bose QuietComfort or AE2 pads are cracked, shiny or flattened, I would buy the Krone Kalpasmos Professional Replacement Bose — in my opinion it is the smarter purchase, because it protects the ANC and sound you already invested in for a fraction of replacing the headphones, and the three-year manufacturer warranty is unusually generous for a wear item. If your problem is that nothing is comfortable to sleep in, I would buy the Perytong Sleep Headphones instead. The honest framing: one restores noise cancelling, the other sidesteps the need for it by being soft enough to forget. Check the current price on Amazon before deciding, and confirm your exact Bose model is on the compatibility list first.
how to replace ear pads on bose noise cancelling headphones
The Krone Kalpasmos kit includes the necessary tools and replacement parts, and the brand provides step-by-step installation guidance in the box. The process is described as taking only a few minutes. Work gently around the mounting ring so the new cushion seats evenly — an uneven seal is what kills noise cancelling performance.
what is the best noise cancelling over ear headphones
I can't hand you a universal winner, but here is the useful angle: over-ear ANC depends heavily on the ear cushion seal. If you already own a compatible Bose QuietComfort or AE2 model, refreshing the pads with Krone Kalpasmos is the cheapest way to get that seal — and therefore the noise cancelling — back to how the headphone was designed to perform.
what are the best noise cancelling in ear headphones
For true in-ear isolation you need something that physically blocks the canal, and the Perytong Sleep Headphones are not that — they are an on-ear headband with noise control listed as none. What they do offer is a soft fabric alternative that reduces surrounding noise without anything inserted into your ear, which is why side sleepers tend to prefer them.
are replacement ear pads worth it compared to buying new headphones
Based on the specs, yes, if the rest of your Bose headphone is healthy. The pads use protein leather over memory foam, are rated for 12 months or more of use, and are designed to maintain the original sound and noise cancelling. Replacing a worn consumable part is almost always cheaper than replacing the whole unit.
