How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a light-blocking sleep mask that doubles as a built-in white-noise machine for motorcycle trips and hotel rooms, choose Easysleep 3D; if you need real active noise cancellation that quiets an engine, snoring or traffic, choose Ertuly T33. These two "sleep headphones" solve the same problem in completely opposite ways, and the right one depends on whether you want to mask sound or cancel it.
• Easysleep 3D biggest strength: A 3D contoured eye mask with a deep eye socket that blocks light while 31 built-in soothing sounds play — no phone, no pairing, no charging cable dangling across your pillow.
• Easysleep 3D biggest trade-off: It does not cancel noise. It plays white noise, fan sounds and nature sounds over the noise — masking, not eliminating. And it's a full over-the-eyes mask, not an earbud.
• Ertuly T33 biggest strength: Hybrid ANC that neutralizes up to 98% of disruptive sound, with 8 hours per charge and 48 hours total from the case.
• Ertuly T33 biggest trade-off: No light blocking at all, and it's a true wireless earbud you have to charge, pair over Bluetooth and keep track of — two tiny buds instead of one mask.
• Pick Easysleep 3D if you're a side sleeper, a traveler or a motorcyclist who wants darkness plus a steady soundscape in one piece of gear.
• Pick Ertuly T33 if the noise around you is loud and specific — snoring, traffic, appliance hum — and you want it actively reduced rather than covered up.
The Easysleep 3D is a sleep mask first and a sound device second. The 3D contoured eye socket is built deeper than a flat mask so it sits off your eyelids instead of pressing on them, and the adjustable strap is meant to fit any head size. The claim is 100% light blocking, and the design logic supports it: full coverage, a shape that seals against the skin, and a soft cotton build that weighs 1.92 ounces. That's the whole point — no pressure on the eyes, no light leaking in at the nose bridge.
What makes it unusual is the audio. There are 31 preloaded soothing sounds — white noise, fan sounds, nature sounds and ambient sounds — with a 30- or 60-minute timer or a continuous-play option for all night. There's also a memory feature that recalls your last volume, track and timer, which matters more than it sounds: you set it once, and every night after that it comes back the way you left it. It's a small thing that removes friction from a bedtime routine.
Ertuly T33: Who It's For
The Ertuly T33 takes the opposite approach. It's a pair of true wireless in-ear buds — model sleepbuds-T33 — with dual-microphone Hybrid ANC that the spec sheet says neutralizes up to 98% of disruptive sounds like snoring, traffic and appliance hum. A triple-tap switches between ANC and Transparency Mode, so you can shut the world out or let it back in without pulling a bud out. That toggle is genuinely useful: full cancellation for sleep, transparency when you need to hear an alarm or a kid.
The comfort story is aimed squarely at side sleepers. The buds are small, low-profile and made from skin-friendly silicone, designed to sit snugly without pressure whether you're on your back or your side. That's the hardest problem in sleep audio, and Ertuly is clearly designing around it rather than around sound quality for music.
Battery is where the T33 pulls ahead on paper: 8 hours of playback per charge, 48 hours total with the case, a 1.5-hour USB-C recharge, and an LED battery indicator on the case so you're not guessing. Bluetooth 6.0 with a 10-meter range, dynamic drivers at 38 ohm impedance, touch media controls, and a one-year warranty round out the package. It ships in Navy with the case, cable and manual.
Who should buy it: anyone whose sleep is broken by a specific, persistent noise, and anyone who wants to fall asleep to their own audio — a podcast, an audiobook, a playlist — rather than a fixed library of sounds. Who should skip it: people who need darkness. There is no eye coverage here at all. If light is your problem, the T33 does nothing for it. And if you lose small objects easily, two tiny buds plus a case is a genuinely different commitment than one mask.
Side-by-Side: Which Should You Choose?
• Best for blocking light → Easysleep 3D. The 3D contoured mask is built to seal out light; the T33 has no eye coverage whatsoever.
• Best for battery and charging convenience → Ertuly T33. 8 hours per charge, 48 hours total, 1.5-hour USB-C top-up and an LED indicator on the case.
• Best for zero-setup use → Easysleep 3D. No pairing, no app, no charging routine — 31 built-in sounds and a memory feature that recalls your last setting.
• Best for side sleepers → Both, for different reasons. The T33's low-profile silicone buds are designed to avoid ear pressure; the Easysleep 3D avoids eye pressure. Which pressure bothers you more decides it.
• Best for your own audio → Ertuly T33. Bluetooth 6.0 wireless streaming means any track, podcast or audiobook you want, within 10 meters.
• Best for travel and naps → Easysleep 3D. One flat, packable piece of gear that does light and sound together — good for a plane, a train, a hotel or a motorcycle trip.
• Best for hearing your surroundings on demand → Ertuly T33. The triple-tap Transparency Mode is the only one of the two that lets the outside world back in without taking anything off.
If I had to pick one, I'd buy the Ertuly T33. In my opinion, active noise cancellation is the feature that actually solves the sleep problem most people have — snoring, traffic, hum — and 48 hours of total playtime with a 1.5-hour recharge means it won't become a chore. That said, if you need darkness more than you need silence, or you want a single piece of gear for a motorcycle trip where you're blocking light and masking road noise at the same time, the Easysleep 3D is the smarter buy. Check the current price on Amazon before you decide — both are worth comparing on value once you see today's numbers.
how to block out noise with headphones
There are two approaches, and these two products represent both. You can mask sound by playing white noise, fan sounds or nature sounds over it — that's what the Easysleep 3D does with its 31 built-in tracks. Or you can actively cancel it with hybrid ANC, which is what the Ertuly T33 does, neutralizing up to 98% of disruptive sound. Cancellation works better on steady low-frequency noise like engines and hum; masking works on almost anything but doesn't remove it.
are there noise cancelling headphones for sleeping
Yes. The Ertuly T33 is designed specifically for that: true wireless in-ear buds with dual-microphone Hybrid ANC, a dedicated Sleep Mode, and small silicone tips meant to stay comfortable for side sleepers. The Easysleep 3D is also sold as sleep headphones, but it does not cancel noise — it plays soothing sounds inside a light-blocking mask. Both are sleep-oriented; only one of them cancels.
is it safe to wear noise cancelling headphones while sleeping
The T33 is built for exactly that use, with low-profile buds designed to avoid ear pressure and a Transparency Mode you can switch on with a triple-tap if you want to hear your surroundings. The practical cautions are the usual ones for anything you wear overnight: keep the volume low, and make sure you can still hear an alarm. The Easysleep 3D avoids the question entirely since nothing goes inside your ear.
what are the best noise cancelling sleep headphones
For cancellation specifically, the Ertuly T33 is the stronger choice on paper — Hybrid ANC rated up to 98%, Bluetooth 6.0, 8 hours per charge and 48 hours with the case. If your priority is blocking light and masking sound in one device rather than cancelling it, the Easysleep 3D is the better fit. In my opinion, decide which problem is bigger — light or noise — and the answer picks itself.
