How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an all-in-one sleep, travel and relaxation headband that replaces earbuds and doubles as a sleep mask, choose CozyPhones Sleep Headphones; if you need to restore a pair of Koss UR20 headphones you already own with fresh leather-and-foam earpads, choose YDYBZB Ear Pads Cushions.
• CozyPhones Sleep Headphones — biggest strength: a washable Lycra headband with ultra-thin over-ear speakers, a flexible 1.5-meter braided cord and a 3.5 mm plug, built for side sleepers, meditation, travel and kids.
• CozyPhones Sleep Headphones — biggest trade-off: it's a complete headband system, not a repair part — if you already own a specific pair of headphones you love, it won't fix or upgrade them.
• YDYBZB Ear Pads Cushions — biggest strength: a targeted replacement set of leather and high-elastic-cotton earpads made specifically for the Koss UR20, designed for long-term, crack-free durability and all-day comfort.
• YDYBZB Ear Pads Cushions — biggest trade-off: it's a repair accessory only — no drivers, no cable, no headband, and it fits the Koss UR20, not other models.
• Choose CozyPhones if you want a new, self-contained way to listen in bed, on a plane or during yoga without anything pressing into your ears.
• Choose YDYBZB if your Koss UR20 pads are worn out and you want to keep the headphones you already have comfortable again.
CozyPhones is a headband first and a headphone second. The design puts ultra-thin speakers inside a soft Lycra band that sits over your ears instead of inside them, which is the whole point: nothing is jammed into your ear canal, and there are no bulky cups to dig into your head when you roll onto your side. The band is adjustable at the speakers, so you can line them up with your ears, and it's machine washable once you slide the speakers out. For anyone who has woken up with sore ears from earbuds, that combination is the reason to look at this product.
The specs back up the "gentle listening" angle. The drivers are balanced armature with a 32-ohm impedance and a 20 Hz–20 kHz frequency range, and the built-in volume-limiting circuitry keeps output within 90 dB — a level the brand frames as safe for young children's ears. That makes it a genuinely family-oriented product: kids, teens, dorm residents with noisy roommates, and anyone sharing a room with a snoring partner. It's also pitched at meditation, yoga, running and laptop or phone listening, and the 1.5-meter braided cord with a 3.5 mm stereo plug means it works with basically any device that still has a headphone jack.
Who should skip it? If you want wireless freedom, note that the sheet lists both wired and wireless connectivity but the headband's core setup is a 3.5 mm cable — so plan around a cord. And if your actual problem is a pair of Koss UR20 headphones with crumbling pads, this does nothing for you. In my opinion, CozyPhones is for the person who wants a new, softer listening habit, not a repair.
YDYBZB Ear Pads Cushions solve one narrow problem very well. They're replacement earpads — a single pair of foam cushions wrapped in professional-grade leather, made specifically to fit the Koss UR20 over-ear headset. The package is just the pads; the headphones themselves aren't included, and there are no drivers, cables or headband parts in the box. If that's what you need, that's exactly what you get, with no extras to pay for.
The materials are the story here. The leather is described as designed for long-term, crack-free durability, and the foam core is high-elastic cotton, which is the combination that keeps a pad from flattening into a hard disc after months of use. The stated goal is comfort to the point of forgetting the headphones are on — which is the real reason people replace pads in the first place. Worn-out pads change not just comfort but how a headphone sits on your head, so refreshing them is often the cheapest way to keep a pair you already like in rotation.
Who should skip it? Anyone who doesn't own Koss UR20 headphones. Compatibility is limited to that model, and the color is black — there's no variety to choose from. If you're shopping for a new listening device rather than fixing an old one, this product simply isn't in the same category as CozyPhones. In my opinion, YDYBZB is for the practical buyer: you have the headphones, you like them, and you want them comfortable again.

• Best all-rounder for a new listener → CozyPhones Sleep Headphones. It covers sleep, relaxation, exercise and everyday listening in one product.
In my opinion, CozyPhones Sleep Headphones is the pick for most people reading this, because it solves a broader problem: how to listen comfortably in bed, on a plane or during quiet time without earbuds hurting your ears. The washable headband, thin over-ear speakers and 90 dB volume limiting make it flexible across sleep, meditation and kids' use. I'd only choose YDYBZB Ear Pads Cushions if I already owned Koss UR20 headphones and just needed to bring the pads back to life — in that case it's the smarter, more targeted buy. Two different jobs, two different answers. Check the current price on Amazon for whichever one matches your situation.
FAQ
No. The data sheet lists compatibility with the Koss UR20 over-ear headset specifically, and that's the only model named. If you own a different headphone, these pads aren't the right fit.
Yes. The speakers are removable, and the headband itself is machine washable — so you can clean it after travel or regular use and keep it fresh.
The pads use leather over high-elastic cotton foam, and the brand describes them as built for long-term, crack-free durability and comfort you forget about. That said, how they feel depends on your Koss UR20's fit and clamping force, which the pads don't change.
