• LC-dolida Sleep Mask — biggest strength: A true 2-in-1 design that combines total blackout with Bluetooth V5.2 audio, so you can fall asleep to music or white noise without wearing anything else on your head.
• LC-dolida Sleep Mask — biggest trade-off: It's a sleep aid first. There's no active noise cancelling, and the built-in speakers are meant for quiet listening in bed, not for drowning out a jet engine.
• Anker Soundcore Space 2 — biggest strength: A 4-stage low-frequency active noise cancelling system plus up to 50 hours of playtime with ANC on — genuinely built for long journeys.
• Anker Soundcore Space 2 — biggest trade-off: It's an over-ear headphone. Great for sitting upright on a plane, awkward if you sleep face-down or on your side.
• Pick LC-dolida Sleep Mask if you want to block light and drift off to audio at home, in a hotel or on a red-eye.
• Pick Anker Soundcore Space 2 if you want to silence the world around you while you're awake and travelling.
The LC-dolida Sleep Mask does one thing that most headphones simply cannot: it lets you listen to audio while your head is on a pillow. The memory foam body with an ice-silk lining is designed to sit flat against your face, and the full-coverage shape with its dedicated nose area is built to stop light leaking in around the edges. That combination — blackout plus sound — is the whole point. If you're a side sleeper, a shift worker trying to sleep in daylight, or someone who needs white noise to switch off, this is the category of product made for you.
The audio side is sensible rather than spectacular. Bluetooth V5.2 handles the wireless connection, there's a built-in microphone so you don't miss a call, and the battery charges in about 1–2 hours for 8–10 hours of playback — roughly a full night. The speakers sit inside the mask and are meant to be nudged into position over your ears, so this is close-range listening, not room-filling sound. Think a podcast, a sleep playlist, a meditation track.
Who should skip it? Anyone expecting real noise cancelling. The mask muffles and covers, and the fabric is hypoallergenic and breathable, but it won't erase a snoring partner or a cabin full of engine drone. If your problem is loud noise rather than light and restless nights, the LC-dolida is the wrong tool. It also ships as one size, so fit is a fixed proposition rather than something you adjust. In my opinion it's the better buy for the bedroom and the overnight flight seat — not for the airport terminal.
The Soundcore Space 2 is the opposite philosophy: put a proper pair of over-ear headphones on and make the noise go away. Anker's 4-stage low-frequency noise cancelling system is explicitly aimed at the sounds of travel — jet engines and environmental rumble — which is why this is best understood as a travel headphone first. The oval over-ear cups use protein leather with slow-rebound memory foam, and the ergonomic headband is shaped to relieve pressure on long-haul flights. At 264 g it's a real piece of hardware, but it's built to be worn for hours at a time.
Battery is where it pulls clearly ahead. Anker rates it at up to 50 hours with ANC on and 70 hours with ANC off, and a 5-minute charge buys about 4 hours of listening. For a long trip that's the difference between packing a charger and not thinking about it at all. The 40 mm dynamic drivers cover a 20 Hz–20,000 Hz range and support LDAC Hi-Res audio, so this is a music-first product, not just a noise blocker.
There's also a feature that overlaps neatly with the sleep-mask use case: Nap Mode in the soundcore app serves up built-in soundscapes — white noise-style audio — with one tap. Add dual connection, wearing detection and AI-assisted clear calls, and you get a headphone that handles work calls, music and quiet time in one device. Skip it if you sleep on your side or face-down, or if you want something you can wear in bed without a headband pressing into your skull. It's a travel essential, not a pillow companion.
• Best for sleeping in any position → LC-dolida Sleep Mask. Memory foam and ice silk let you lie on your side; over-ear cups don't.
• Best for blocking loud engine and cabin noise → Anker Soundcore Space 2. Active noise cancelling is its core feature; the LC-dolida has none.
• Best for battery life → Anker Soundcore Space 2. Up to 50 hours with ANC on, 70 with it off, versus 8–10 hours for the mask.
• Best for an overnight red-eye where you actually sleep → LC-dolida Sleep Mask. Blackout coverage plus audio is exactly what a night flight calls for.
• Best for music quality → Anker Soundcore Space 2. 40 mm drivers, LDAC Hi-Res support and a 20 Hz–20,000 Hz range put it in a different league.
• Best for calls and work → Anker Soundcore Space 2. Dual connection, wearing detection and a clear-call setup make it a daily driver.
• Best for falling asleep at home or in a hotel → LC-dolida Sleep Mask. The nose-area design and full coverage target light leakage, not sound leakage.
• Best for travel where you're awake and moving → Anker Soundcore Space 2. The travel pouch, fast charging and ANC are all pointed at the journey.
If I had to pick one, I'd go with the Anker Soundcore Space 2. In my opinion it's the more versatile travel essential: real noise cancelling, enough battery for the longest trip, LDAC audio for music and calls, and Nap Mode for the moments you want soundscapes instead of a playlist. The LC-dolida Sleep Mask is excellent at a narrower job — sleeping with audio and no light — and if your main problem is falling asleep at home or on a night flight, it's the one I'd hand you. But as a single purchase that covers flights, trains, offices and everything in between, the Space 2 earns my recommendation. Check the current price on Amazon before you commit, since that's the one thing that can genuinely tip this decision.
FAQ
For sleeping specifically, yes — in my opinion. It's designed to be worn lying down, blocks light with full coverage and a dedicated nose area, and lets you play audio without extra headphones. Noise cancelling headphones are built for upright listening, not for a pillow.
Not for light blocking. It has no eye coverage at all. Nap Mode gives you built-in soundscapes to help you wind down, but if you need darkness to sleep, you still need a mask like the LC-dolida.
The Anker Soundcore Space 2 by a wide margin. It's rated up to 50 hours with ANC on and 70 hours off, with a 5-minute charge giving about 4 hours of playback. The LC-dolida offers 8–10 hours per charge, which covers one night.
Honestly, they solve different problems, so plenty of travellers would. Use the LC-dolida for actual sleep — at home or on an overnight flight — and the Space 2 for the awake part of the journey, calls, music and blocking cabin noise.
