If you want built-in white noise and a washable mask you can run without your phone, choose LC-dolida Sleep Mask; if you need a newer Bluetooth version, USB-C charging and a bamboo-cotton fabric with an adjustable strap, choose ZHENYEMEI Sleep Headphones.
• LC-dolida Sleep Mask — biggest strength: 8 built-in white noise tracks you can trigger with one click, no phone pairing needed, plus a Bluetooth module that pops out so the mask itself can be machine washed.
• LC-dolida Sleep Mask — biggest trade-off: It relies on standard Bluetooth (no version stated) and a 2-hour charge for 8–10 hours of playback, and the fabric is nylon rather than a natural fiber.
• ZHENYEMEI Sleep Headphones — biggest strength: Bluetooth 5.4 with Hi-Fi stereo, a microphone, USB-C charging that tops up in 1–2 hours for 10+ hours of playback, and a bamboo-cotton fabric described as moisture-wicking.
• ZHENYEMEI Sleep Headphones — biggest trade-off: No built-in white noise library — everything you listen to has to come from a paired device, and it's the heavier of the two at 5.61 ounces.
• Who each pick is for: LC-dolida is for the person who wants to fall asleep with white noise and zero phone involvement; ZHENYEMEI is for the person who wants current Bluetooth, a headset mic for calls, and a softer natural-feel fabric.
The LC-dolida Bluetooth Sleep Mask is built around one idea: get you asleep without reaching for your phone. It carries 8 pre-loaded white noise tracks you switch with a single click, so on a plane, in a shared bedroom or during a midday nap you can block out the room without opening an app. When you do want music or a podcast, Bluetooth pairing gives you 8–10 hours of playback off a 2-hour charge.
The eye cover is nylon — lightweight, breathable and soft, in a light purple, solid pattern. It's a low-profile design with speakers tucked in so they don't dig into your face when you roll onto your side. In my opinion, that combination makes it the better pick for side sleepers who mainly want masking sound rather than audio quality.
Skip it if you care about the newest Bluetooth standard, want a microphone for calls, or prefer a natural-fiber fabric. There's no stated Bluetooth version and no mic here, and it's clearly designed as a sleep-first device rather than a wearable headset. Also skip it if you want to listen to your own playlists all night — with 8–10 hours of playback you'll likely need a charge partway through a long session.
ZHENYEMEI Sleep Headphones: Who It's For
The ZHENYEMEI Sleep Headphones is the more tech-forward of the two. It runs Bluetooth 5.4 — the newest version in this comparison — with Hi-Fi stereo sound and an included microphone, so it doubles as a headset for a call or a voice memo, not just a sleep aid. The USB-C port charges in about 1–2 hours and delivers 10+ hours of playback, which covers a full night for most people.
Comfort is where ZHENYEMEI makes its case. The fabric is 100% bamboo cotton, described as infused with negative oxygen ions and engineered for breathability, moisture wicking and skin comfort. It's blue, solid, and slightly larger in the package than the LC-dolida. An adjustable Velcro strap adapts to different head shapes, and the added cushioning plus an "adjustable cartilage design" are aimed squarely at side sleepers and light-sensitive travelers.
Same story on cleaning: components come out so the mask can be fully washed. A battery is included and required.
Side-by-Side: Which Should You Choose?

If I were buying for myself, I'd take the ZHENYEMEI Sleep Headphones. Bluetooth 5.4, USB-C charging and 10+ hours of playback are the specs that matter most night after night, and the bamboo-cotton fabric with an adjustable Velcro strap sounds like the more comfortable long-term wear for a side sleeper. The microphone is a genuine bonus.
That said, if your real problem is a racing mind at 2 a.m. and you don't want a phone anywhere near the bed, the LC-dolida Sleep Mask solves it more directly — 8 built-in white noises, one click, done. Pick on that single question and you won't regret either.
ZHENYEMEI states 10+ hours of playback from a 1–2 hour USB-C charge. LC-dolida states 8–10 hours from a 2-hour charge. On paper, ZHENYEMEI edges ahead and charges faster.
Yes. Its 8 white noise tracks are built in and switched with one click, so you can use it with no paired device at all. The ZHENYEMEI mask has no built-in sounds and needs a paired device.
Both are, and both solve it the same way — the electronics come out first. LC-dolida's module detaches so the nylon mask can be machine or hand washed; ZHENYEMEI's components are removable for full washing of the bamboo cotton.
Both are designed with side sleepers in mind and use low-profile speakers. ZHENYEMEI adds extra cushioning and an adjustable Velcro strap; LC-dolida is slightly lighter and pairs that with built-in white noise. If you want the lighter mask, go LC-dolida; if you want the more adjustable fit, go ZHENYEMEI.
