How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single device that doubles as a light-blocking sleep mask and a white-noise machine for long flights and hotel nights, choose LC-dolida Sleep Headphones; if you need serious active noise cancellation, big over-ear drivers and marathon battery life for commuting and air travel, choose 1Mii E700.
• LC-dolida Sleep Headphones — biggest strength: an all-in-one sleep mask with built-in Bluetooth 5.2 speakers and 8 built-in white-noise sounds, so you can drift off without even pairing your phone.
• LC-dolida Sleep Headphones — biggest trade-off: it's a soft memory-foam mask with small adjustable speakers, not a hi-fi headphone, so it won't deliver the deep bass or isolation of an over-ear pair.
• 1Mii E700 — biggest strength: hybrid active noise cancellation, 40 mm dynamic drivers, LDAC Hi-Res support and a rated 54-hour average battery life in a proper over-ear design.
• 1Mii E700 — biggest trade-off: it's a full-size headphone that needs to be carried in its case, and it won't block cabin or window light the way a mask does.
• Who each pick is for: the LC-dolida is for side sleepers, nappers and light-sensitive travelers; the 1Mii E700 is for commuters and flyers who want to shut out engine drone and chatter.
This is a sleep-first product. The core idea is that the mask and the headphones are the same object: memory foam with a 3D contoured eye area, a shaped nose cutout for full light coverage, and adjustable speakers tucked inside. You put it on, and you're both in the dark and listening. For a red-eye flight or a hotel room with a gap in the curtains, that combination solves two travel problems with one item in your bag.
The part I find genuinely clever is the white-noise mode. There are 8 built-in relaxing sounds, and you can select white-noise mode without connecting Bluetooth at all. That matters on a plane where you don't want to fumble with pairing, and it matters at home when you just want to fall asleep. When you do want audio, Bluetooth 5.2 handles the connection, and there's a built-in microphone for hands-free calls.
Battery is a 240mAh cell rated at roughly 2 hours to charge and more than 10 hours of playback — enough for a full night. There's also a 30–120 minute timer so playback stops after you've nodded off instead of running all night. The electronics are removable, which makes the mask washable.
1Mii E700: Who It's For
The E700 is built for the opposite job: blocking out the world while you're awake and moving. It's an over-ear design with oval earcups, a mix of faux leather, memory foam, metal and plastic, and a dedicated carrying case that measures about 8.66 by 6.69 by 2.5 inches. That case is the tell — this is a headphone meant to travel in a bag, not to be slept in.
The headline feature is hybrid active noise cancellation, with modes you can switch through the YeeMall app alongside battery status, auto power-off and soothing sounds. The audio hardware is a 40 mm dynamic driver with a 20 Hz–40 kHz frequency range, 24 ohm impedance and 105 dB sensitivity, plus LDAC Hi-Res support for higher-quality wireless playback on compatible phones. There's also aptX low-latency, which is the mode you'd want when watching a seatback screen or a TV, where audio lag is obvious.
Battery is where it pulls away: a rated 54 hours of average life and about 3 hours to charge. Even accounting for real-world variation, that's measured in days of commuting, not hours. Controls are button-based plus app-based, covering volume, calls, noise control and voice assistant, and there's a USB-C jack plus an AUX-to-USB-C cable so you can run it wired when you want.
Who should buy it: commuters, frequent flyers, open-office workers, and anyone who wants one headphone for music, calls, TV and noise blocking. Who should skip it: side sleepers, people who need total darkness to fall asleep, and anyone who wants the absolute minimum to pack — the case is a real object in your bag.
Side-by-Side: Which Should You Choose?
• Best for sleeping and napping → LC-dolida Sleep Headphones. It's a mask with speakers, timer and built-in white noise; the E700 is not designed to be worn in bed.
• Best for blocking engine and cabin noise → 1Mii E700. Hybrid ANC is the whole point of this model; the LC-dolida relies on passive light blocking, not noise cancellation.
• Best for battery life → 1Mii E700. A rated 54-hour average life against the LC-dolida's 10+ hours, though the LC-dolida covers a full night's sleep comfortably.
• Best for light sensitivity on a plane → LC-dolida Sleep Headphones. Full-coverage eye area and a shaped nose cutout are features the E700 simply doesn't have.
• Best for watching a seatback screen → 1Mii E700. aptX low-latency is built for exactly this; the LC-dolida is tuned for music and white noise, not lip-sync.
• Best for packing light → LC-dolida Sleep Headphones. It's a soft mask that folds into a corner of a bag; the E700 travels in its own case.
• Best for hands-free calls in a noisy terminal → 1Mii E700. Button and app call control plus ANC on a proper over-ear platform.
If I had to pick one for travel overall, I'd buy the 1Mii E700. In my opinion, the combination of hybrid ANC, LDAC Hi-Res audio, aptX low-latency and a rated 54-hour battery makes it the more versatile travel headphone — it handles a flight, a train, a hotel room and a noisy gate without compromise. But I'd happily recommend the LC-dolida Sleep Headphones as a companion, not a replacement. If your real problem is falling asleep on planes and in unfamiliar rooms, and especially if you sleep on your side, the mask-with-white-noise approach is the one that actually fits the job. Check the current price on Amazon before deciding, since both sit in very different budget brackets.
FAQ
what is the best headphones for traveling
what are good headphones for travel
Good travel headphones need to isolate noise, last a long flight, and pack sensibly. The 1Mii E700 covers isolation with hybrid ANC, offers LDAC Hi-Res audio and aptX low-latency for seatback screens, and comes with a fabric carrying case. The LC-dolida covers a different need: darkness plus white noise in one washable mask.
how to pack headphones for travel
For the 1Mii E700, use the included case — it's roughly 8.66 by 6.69 by 2.5 inches and keeps the earcups protected in a backpack. For the LC-dolida, remove the Bluetooth module and wires, and the soft memory-foam mask can be flattened into a pocket or packed around other items.
how to wrap headphones for travel
The E700 doesn't need wrapping — the case is the wrap, and folding an over-ear headphone usually stresses the headband more than it saves space. The LC-dolida is the opposite: take out the electronics so the mask is washable and flexible, then roll it loosely. In both cases, keep cables coiled rather than sharply bent.
