If you want one pair of headphones that survives open water, pool laps and sweaty road rides while still letting your ears stay open to traffic, choose MUXUN Bone Conduction Headphones; if you need something that blacks out the light, disappears into a pillow and plays soft audio until morning, choose ZHENYEMEI Sleep Headphones. These two look like they belong in the same shopping cart, but they solve completely different problems — one is a training tool, the other is a sleep tool.
• MUXUN's biggest strength: an IP68 triple-sealed body that can sit two meters underwater for two hours, paired with a 32GB on-board MP3 player so you never need a phone or a Bluetooth signal near the water.
• MUXUN's biggest trade-off: it's an open-ear sports band, not a sleep mask — there's no light blocking, no pillow-friendly cushioning, and the sound is delivered through bone conduction rather than sealed ear cups.
• ZHENYEMEI's biggest strength: a 100% bamboo cotton eye mask with adjustable cartilage-style padding and a Velcro strap that blocks light completely and stays comfortable for side sleepers.
• ZHENYEMEI's biggest trade-off: it is not built for water. Nothing in its spec sheet claims water resistance, so sweat, rain and pools are out of scope.
• Who MUXUN is for: swimmers, runners, cyclists and anyone training outdoors who wants music with situational awareness.
• Who ZHENYEMEI is for: side sleepers, frequent flyers, shift workers and light-sensitive nappers who want audio inside a mask.
This is a swim-first device. The headline number is the IP68 rating with a triple-sealed construction, and the sheet is specific about what that means: submersion up to two meters deep for two hours. That covers pools, ocean swims and freshwater lakes. The reason that matters isn't durability bragging — it's that swimming is the one sport where Bluetooth genuinely fails you, because water kills the signal between your phone and your head. MUXUN solves it the honest way: short-press the M button for two seconds to jump into MP3 mode, and your audio comes off the built-in memory instead of the air. You load songs by plugging in the data cable and dragging files across from a computer. Simple, slightly old-school, and completely reliable at the pool.
Who should buy it: swimmers who want music without a waterproof phone pouch, runners and cyclists who refuse to plug their ears, and anyone who wants a single headphone for land and water. The fit is slim and lightweight, and the sheet notes it integrates with swim caps, goggles, sunglasses and bike helmets, with physical buttons that are easy to find mid-lap — volume, mode switching, all reachable without looking. Who should skip it: anyone whose main goal is falling asleep. There's no light blocking here, no pillow cushioning, and an open-ear band is the wrong shape for lying on your side. If you want a sleep product, this isn't it.
ZHENYEMEI Sleep Headphones: Who It's For
ZHENYEMEI takes the opposite approach: it hides the audio inside something you'd wear anyway. The shell is 100% bamboo cotton, described as breathable, moisture wicking and skin-friendly, with negative-ion-infused fiber meant to feel like mountain air against your face. That's the pitch, and the practical upshot is a soft fabric mask rather than a hard plastic band pressing on your temples at 2 a.m.
The design details are where this one earns its place. It combines a sleep mask and Bluetooth headphones in one unit, and the sheet specifically calls out side sleepers — the group that most often gives up on sleep headphones because the speakers dig into their ear or the strap shifts. The light blocking is handled with an adjustable cartilage-style design plus extra cushioning, which is the part frequent travelers and light-sensitive sleepers care about most. The adjustable Velcro strap adapts to different head shapes, so it stays put whether you're in your own bed or a red-eye seat.
Audio is Bluetooth 5.4 with stereo sound and a built-in microphone, so it pairs like a normal headset and handles calls. Battery is rated at 10+ hours of playback from roughly 1–2 hours of charging via USB-C — enough to cover a full night without waking up to a dead mask. And because it's fabric against your face every night, the removable components matter: they come out so the whole thing can be washed. That's a detail cheap sleep masks skip, and it's the difference between a product you keep using and one you quietly stop wearing.
Who should buy it: side sleepers, people who need total darkness to fall asleep, frequent flyers, shift workers, and anyone who wants to drift off to a podcast or white noise without earbuds. It's also an easy gift — the sheet frames it that way for good reason, since it's a gadget that doesn't require the recipient to be a tech person. Who should skip it: swimmers and heavy sweaters. There is no water-resistance claim anywhere in this spec sheet, and a bamboo cotton mask is the last thing you want in a chlorinated pool.
• Best for swimming → MUXUN Bone Conduction Headphones. IP68, two meters for two hours, MP3 mode instead of Bluetooth underwater.
• Best for sleep and light blocking → ZHENYEMEI Sleep Headphones. Bamboo cotton mask, adjustable padding, full darkness.
• Best battery for a long session → effectively a tie, with a twist. MUXUN rates 8 hours plus a 10-minute quick charge for up to 3 hours; ZHENYEMEI rates 10+ hours from a 1–2 hour USB-C charge. ZHENYEMEI lasts longer per charge, but MUXUN recovers faster when you're short on time.
• Best for side sleepers → ZHENYEMEI Sleep Headphones. Built around side-sleeping comfort and an adjustable Velcro strap.
• Best for outdoor safety → MUXUN Bone Conduction Headphones. Open-ear bone conduction keeps you aware of traffic and surroundings.
• Best for travel → ZHENYEMEI Sleep Headphones. The mask does double duty blocking cabin light and playing audio.
• Best for off-grid music → MUXUN Bone Conduction Headphones. 32GB of on-board storage plus a no-jack wireless design means no phone required.
• Best for washing and hygiene → ZHENYEMEI Sleep Headphones. Removable components make the mask fully washable; MUXUN is a sealed electronics unit.
My Verdict
Yes, according to its spec sheet. It carries an IP68 rating with a triple-sealed design and is rated for submersion up to two meters for two hours, covering pools, ocean and freshwater lakes. Just remember to switch to MP3 mode — Bluetooth doesn't work well underwater.
That's exactly what they're designed for. The mask combines light blocking with Bluetooth audio, and the sheet specifically notes side sleepers, an adjustable Velcro strap and extra cushioning. Battery is rated at 10+ hours, so it should last the night.
Connect the data cable to a computer and transfer your downloaded songs onto the device, then switch to MP3 mode with a two-second press of the M button. That's the mode you use in the water.
Yes — both products sit in different budget brackets depending on the seller and the moment, and I don't quote prices here. Use the "Check latest price on Amazon" button on this page to see the current figure for each before you decide.
