If you want a washable, all-night sleep headband you can wear lying on your side, choose Perytong 2-Pack; if you need headphones that survive full submersion in the pool and store music on board, choose RR SPORTS IP68. Two very different answers to the same search, and the wrong pick will annoy you within a week.
• Perytong 2-Pack — biggest strength: an ultra-thin on-ear disc inside a soft, fully washable spandex headband, so there's no hard plastic digging into your ear or temple when you roll onto your side.
• Perytong 2-Pack — biggest trade-off: no IP rating and no waterproofing claim, so sweat and rain are fine on a run but a swimming pool or a shower is not its job.
• RR SPORTS IP68 — biggest strength: IP68 sealing rated for submersion up to 2 meters, plus a built-in 32GB MP3 player that holds roughly 7,000 songs so you can swim without a phone anywhere near the water.
• RR SPORTS IP68 — biggest trade-off: it's a hook-style open-ear design with bone conduction drivers, so there's no ear cushion to muffle the world, and Bluetooth is specifically not meant to be used while swimming.
• Who each pick is for: Perytong 2-Pack → side sleepers, insomniacs, meditators, nappers, light-blockers, and anyone who wants a spare band in the drawer. RR SPORTS IP68 → lap swimmers, shower listeners, cyclists, and outdoor athletes who need to hear traffic and don't want to carry a phone.
The Perytong 2-Pack is a Bluetooth headband, not a conventional headphone. The drivers sit in extremely thin on-ear discs buried under soft fabric, and the whole thing pulls on like a stretchy sleep mask. The mesh lining is breathable, the material stretches to fit most adult head sizes, and the spandex build is fully washable — you just remove the speakers first. In my opinion, that single design decision is what makes it work for side sleepers: nothing hard presses against your ear when your head is on a pillow.
Functionally, it's a straightforward Bluetooth headband. Stereo speakers and a built-in microphone handle calls, and the on-board volume buttons let you skip tracks and answer the phone without reaching for your phone. The claimed Bluetooth range is 45 feet, which is generous for a bedroom — you can leave the phone charging on a desk and still stay connected. The frequency range is a standard 20 Hz to 20,000 Hz dynamic driver setup, so it's tuned like a normal pair of budget headphones rather than something exotic. Battery life is quoted at more than 14 hours of playback on a roughly 2 to 2.5 hour charge via USB-C, which covers a full night plus a nap the next afternoon. It carries a 2-year warranty.
The practical upside of the two-pack is obvious once you think about laundry day: one band on your head, one in the wash, or one at home and one in a desk drawer at work. It's also the kind of thing that works as a gift for someone who struggles to fall asleep with a TV or a phone playing.
Who should skip it? Anyone who wants to swim. There is no waterproof rating anywhere in the spec sheet, so I would treat this strictly as a dry-land and sleep product. If you want thumping bass or serious noise isolation, a fabric headband is not that product either — it's built for comfort and low volume, not for blocking out the world.
The RR SPORTS IP68 is the opposite philosophy: it's built to go where water goes. The IP68 rating means it's sealed against submersion in up to 2 meters of water, and the construction backs that up with a nano-hydrophobic coating and sealed housing to keep sweat, rain and pool water out of the internals. The manufacturer explicitly notes it can be worn with both swim caps and goggles, which tells you who the target buyer is.
The second half of the story is the 32GB of built-in memory. That's roughly 7,000 songs in MP3, WMA, WAV or FLAC, transferred from a computer over the included magnetic charging cable. That matters because of a limitation worth reading twice: Bluetooth mode is not designed to work while swimming, so underwater listening runs in MP3 mode with no phone involved. For laps, that's actually the cleaner setup — no bag on the pool deck, no signal dropouts.
Around that core, the specs are modern. Bluetooth 6.0 is the version listed, with a range of about 10 meters and up to 7 hours of battery life, compatible with iOS, Android and other devices. The drivers are bone conduction rather than traditional speakers, mounted in a hook-shaped, silicone-bodied open-ear frame. Because nothing plugs your ear canal, you keep hearing ambient noise — safer on a bike or a roadside run, and the manufacturer argues it's gentler on your hearing than in-ear buds. The silicone is described as ultra-soft for extended wear, and the fit is designed to stay put through intense activity.
The trade-offs are real. Seven hours is roughly half what the Perytong headband claims, so on a long day you'll be charging. It's a single unit, not a pair, so there's no spare. Bone conduction sound is a different experience from a conventional driver — it trades deep bass and isolation for awareness. And with a 1-year manufacturer warranty, the coverage window is shorter than Perytong's.
• Best for sleeping and side sleeping → Perytong 2-Pack. Ultra-thin on-ear discs under soft fabric, no hard shell against your ear.
• Best for swimming → RR SPORTS IP68. IP68 submersion protection to 2 meters plus MP3 mode for phone-free laps.
• Best for battery life → Perytong 2-Pack. More than 14 hours of playback versus up to 7 hours on the RR SPORTS.
• Best for listening without a phone → RR SPORTS IP68. 32GB of on-board storage for around 7,000 songs.
• Best for hearing your surroundings → RR SPORTS IP68. Open-ear bone conduction keeps your ears unblocked, which matters on roads and trails.
• Best for washing → Perytong 2-Pack. Fully washable fabric with removable speakers; the RR SPORTS is sealed, not machine-washable.
• Best for two people or a backup → Perytong 2-Pack. You get two headbands, one for home and one for the office or a gift.
• Best for long-range Bluetooth around the house → Perytong 2-Pack. A quoted 45 feet of range versus about 10 meters.
• Best for warranty coverage → Perytong 2-Pack. Two years versus one.
If I were buying for myself and my main goal was falling asleep with audio on and not waking up with a plastic lump under my ear, I'd buy the Perytong 2-Pack — the washable spandex band, the thin drivers and the 14-plus hours of runtime fit that job better than anything with a hard hook. If I were a swimmer or a cyclist who wants music without a phone, I'd buy the RR SPORTS IP68 instead, because IP68 sealing and 32GB of built-in storage solve problems the Perytong band simply isn't designed to solve. In my opinion there's no overlap here: pick by where you'll wear them, not by which sounds nicer on paper. Before you commit, check the current price on Amazon for both.
FAQ
what are the best open ear headphones
are on ear headphones good
Yes, for the right use. The Perytong 2-Pack uses extremely thin on-ear discs inside a washable fabric headband, which is exactly what makes it comfortable for side sleepers — no hard shell pressing into your ear. For critical listening or noise isolation, an on-ear fabric design like this isn't the right tool.
are open ear headphones good
They're good when you need to stay aware of traffic, pool rules or people around you, and the RR SPORTS IP68 is a clear example: bone conduction keeps your ears open while still delivering audio. The trade-off is less bass and no isolation, so they suit sport and outdoor use better than quiet-room listening.
what are the best in-ear headphones
Neither product here is in-ear — both are on-ear designs, one a fabric headband and one an open-ear bone conduction hook. If you specifically want in-ear buds with a sealed fit, look elsewhere; if you want comfort while sleeping or waterproofing for swimming, these two cover those jobs.
