• HAOBSS Sleeping Headphones — biggest strength: memory foam eye mask with a 3D contoured shade system that blocks light, plus detachable speakers and a removable wireless module so the mask itself can be hand washed.
• HAOBSS Sleeping Headphones — biggest trade-off: it's one black fabric-and-foam unit in a single size, the electronics are enclosed inside the mask, and the battery lasts over 17 hours per charge rather than stretching over multiple nights without a top-up.
• Ertuly T33 — biggest strength: hybrid ANC that the manufacturer states neutralizes up to 98% of disruptive sound, with a Transparency Mode toggle and 48 hours of total playtime from the charging case.
• Ertuly T33 — biggest trade-off: it's in-ear, so comfort depends on how the silicone buds sit in your ears; there's no light-blocking benefit at all, and you have to keep track of two small buds plus a case.
• Who each is for: the HAOBSS is for people who want darkness and sound delivered by one washable mask; the Ertuly T33 is for people who want silence delivered by Bluetooth 6.0 earbuds and don't mind wearing something inside their ears.
The HAOBSS Sleeping Headphones is really a sleep mask with speakers built in. The core of the design is the shading system: high-quality memory foam shaped into an extra-long 3D contour that the manufacturer describes as fitting different face types. If your problem is light leaking in around the edges of a normal mask, that contouring is the whole point. It's built with side sleepers in mind, and the soft memory foam is meant to spread pressure rather than press a hard edge against your cheekbone.
The audio side is handled by Bluetooth 5.4 with stereo speakers tucked inside the mask, creating a closed environment for music, audiobooks or white noise. Because the speakers sit against your head instead of inside your ears, nothing is jammed into your ear canal — a real advantage if earbuds make your ears sore after an hour or two. The 250mAh battery is rated for over 17 hours of continuous playback, and it charges over Type-C. Figure two solid nights of sleep per charge if you drift off with audio running.
The detachable design is the detail I appreciate most in this category. The wireless speakers come out and the wireless module lifts out before washing, so the mask doesn't become a grimy piece of electronics you're breathing into every night. Just remember it's hand wash only — no machine washing. The package is a single black mask, one count, about 5.9 ounces, so it's a self-contained unit rather than a system of parts.
Who should buy it? Side sleepers who want total darkness and audio from one object, people who dislike things inside their ears, and anyone who wants a gift-friendly item — the manufacturer explicitly positions it for Christmas, Valentine's Day, and for men, women, teens and parents, with a 1-year manufacturer's warranty. Who should skip it? Anyone who needs active noise cancellation rather than passive sound masking, anyone who wants a size choice, and anyone who hates hand washing. If you need to kill a snoring partner's noise rather than cover it with white noise, this isn't the tool.
The Ertuly T33 takes the opposite approach: instead of covering your eyes, it goes into your ears. These are true wireless sleep earbuds in navy with a plastic charging case, and the headline feature is hybrid ANC — dual microphones that the manufacturer says actively neutralize 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 at night and let it back in when you're moving around.
Comfort is built around a low-profile, ergonomic silicone design that the manufacturer markets specifically for side sleepers — the idea being that the buds sit snug enough to stay put all night without creating a pressure point when your ear meets the pillow. They're in-ear buds with dynamic drivers and 38 ohm impedance, and Bluetooth 6.0 with a 10-meter range handles the connection. Touch controls manage media, and noise control is active rather than passive.
Battery is where the T33 pulls ahead on paper. Each charge gives up to 8 hours of playback, and the case extends that to 48 hours total. A full recharge takes about 1.5 hours over USB-C, and the case has an LED battery indicator so you can see where you stand instead of guessing. The box includes the charging case, the earbuds, a cable and a manual, with a 1-year warranty.
Who should buy it? People who want genuine noise cancellation for sleep, travel or work; anyone who finds a mask over their face claustrophobic; and anyone who wants their sleep audio to last several nights between charges. Who should skip it? Side sleepers who've never gotten along with in-ear buds, people who also need light blocking (the T33 does nothing for that), and anyone who'd rather not manage two tiny earbuds plus a case in the dark. If you want one washable object on your face, this isn't it.
• Best for blocking light → HAOBSS Sleeping Headphones. The memory foam 3D contoured mask is the only one of the two that addresses light at all.
• Best for blocking sound → Ertuly T33. Hybrid ANC with dual microphones is a fundamentally different tool from passive mask-and-speaker audio.
• Best for people who hate earbuds → HAOBSS Sleeping Headphones. Its speakers sit in the mask, not in your ear canal.
• Best for battery life → Ertuly T33. 8 hours per charge and 48 hours total from the case beats 17-plus hours on a single charge.
• Best for hygiene and washing → HAOBSS Sleeping Headphones. Detachable speakers and a removable wireless module mean the fabric can be hand washed.
• Best for side sleepers who want silence → Ertuly T33, provided the low-profile silicone fit works for your ears; the HAOBSS is the safer pick if you've never tolerated in-ears.
• Best for travel and daytime use → Ertuly T33. Transparency Mode, a charging case and a compact in-ear design travel more naturally than a full eye mask.
• Best as a gift → HAOBSS Sleeping Headphones. A single self-contained mask with a 1-year warranty is an easier gift than earbuds whose fit is personal.
In my opinion, most people shopping this comparison should buy the Ertuly T33. Active noise cancellation, 48 hours of total playtime, a charging case with an LED indicator and Bluetooth 6.0 make it the more capable piece of technology, and it works for travel and daytime focus as well as sleep. I'd only steer you to the HAOBSS Sleeping Headphones if darkness matters as much as sound, if earbuds irritate your ears, or if you want one washable object instead of a case full of small parts. Decide which of those two problems you're actually solving, and the choice makes itself. Check the current price on Amazon for whichever one fits.
FAQ
No. The data sheet lists Bluetooth 5.4 and stereo speakers but no ANC. It creates a closed, immersive listening environment — that's masking, not cancelling. The Ertuly T33 is the one with hybrid ANC rated by the manufacturer at up to 98%.
The HAOBSS is rated for over 17 hours of continuous playback from its 250mAh battery. The Ertuly T33 gives up to 8 hours per charge and 48 hours total with the case, recharging in about 1.5 hours via USB-C.
The HAOBSS, by design. The speakers detach and the wireless module comes out so the mask can be hand washed — hand wash only, never machine wash. The T33's buds and case can be wiped down, but there's no washable fabric component.
