The Manta Sound answers a question a surprising number of people have: how do you fall asleep to audio when you sleep on your side and earbuds hurt? Its solution is to build the speakers into the mask — flat Bluetooth panels about as thin as a yoga mat, seated in the strap over your ears, driven by roughly 24 hours of battery. Underneath the audio, it's still a Manta: 100% blackout C-cups with zero eye pressure in a side-sleeper-friendly design, and the electronics pop out so the fabric machine-washes. The combination earned a TIME Best Invention 2025 nod, and it's deserved — this is the most complete audio-plus-darkness product in the category. Our score is more measured than the award, for two honest reasons. At $149, it's by far the most expensive pick in our lineup — three Nidras more than the already-premium Manta Pro — and every dollar of that premium is the audio system, worthless to anyone who doesn't sleep to sound. And it's a premium synthetic mask with electronics: Tactel-class fabric rather than natural fiber (our 25% materials criterion applies as usual), plus a battery to charge and a module to remove on wash day. For the audio sleeper it's a genuine category-of-one product and an easy recommendation. For everyone else, cheaper picks deliver the darkness. Here's the full breakdown.

Read the complete Sleep & Recovery guide →Full blackout from the C-cup design, per Manta's house formula — the listing claims 100% blackout and the cup-plus-strap construction backs it. We score it a shade under the Pro only because the speaker panels in the strap add bulk that slightly constrains how freely the cups reposition on some faces. In practice: dark enough for any bedroom and for daytime sleep.
Premium technical synthetic in the Manta mold — soft, durable, fast-drying — with the C-cup pocket keeping fabric off eyes and lashes. Same honest deduction as the Pro: it's a synthetic worn on the thinnest skin of your face all night, a tier below natural mulberry silk or cotton on our materials-first ranking. The electronics don't touch skin directly; the strap padding sits between speaker and ear.
Zero eye pressure from the C-cups, and the audio layer is engineered not to undo the comfort: the speakers are about as thin as a yoga mat, so side sleepers don't feel a lump between ear and pillow — the single make-or-break spec for a sleep-audio wearable, and Manta nailed it. Slightly below the Pro because the strap carries more hardware and adjusts a little less freely.
The removable-electronics design is what makes a smart mask livable: pop the module out and the fabric machine-washes like any Manta, so nightly-wear hygiene doesn't fight the hardware. Battery is rated around 24 hours of playtime — a couple of nights between charges. The extra moving part (module in/out, charge cycles) is more to maintain than a plain mask, which the score reflects.
$149 is the most expensive pick in our lineup by a wide margin, and the value case depends entirely on whether the audio is a nightly-use feature for you. For the audio sleeper, it replaces both a premium mask and a sleep-headphone purchase, and the price becomes defensible. For anyone else, it's $123 more than the MZOO for the same darkness. We score value for the general buyer, hence the 5.0.
“100% blackout eye mask.”
The Amazon listing title states '100% Blackout,' and the mask uses Manta's C-cup construction — the same design family we scored a perfect 10 on the Manta Pro. We score the Sound 9.4: the blackout is genuinely complete, with a slight allowance for the hardware-carrying strap constraining cup positioning on some faces.
“Bluetooth headphones you can sleep on, even on your side.”
The listing's core claim — Bluetooth sleep audio in a side-sleeper-usable form — is backed by the specific engineering: flat speaker panels roughly as thin as a yoga mat, seated in the strap over the ears rather than in them. This is the one product architecture that survives a pillow, and it's why the product category exists.
“About 24 hours of battery playtime.”
The ~24-hour playtime figure comes from the manufacturer's specifications on the listing. Real-world use — a few hours of audio per night — translates to a couple of nights between charges. Manufacturer-stated spec, not independently bench-tested by us.
“TIME Best Invention 2025.”
The recognition is stated on the manufacturer's listing and matches the product's public positioning. We treat it as a design-credibility signal, not a purchase argument — our 8.2 score prices in the $149 cost and the synthetic-plus-electronics build that the award doesn't weigh.
Sleep audio has always died at the pillow: earbuds ache, over-ear headphones are impossible, and speaker pillows annoy partners. The Manta Sound's flat in-strap panels are the first form factor in our lineup that a side sleeper can actually lie on — thin enough that the pillow doesn't drive them into your head, positioned over the ear so nothing enters the canal. If you've cycled through 'sleep earbuds' and given up, this is the architecture that fixes the problem, and it's the entire justification for the price.
Smart-mask products usually compromise the mask to fit the tech. Manta didn't: the Sound keeps the C-cup zero-pressure blackout that makes the Pro the category's fit benchmark, so you're not trading darkness for audio. That matters because the darkness is the evidence-backed part — light suppresses melatonin (Gooley 2011), and masks improve subjective sleep quality in trials (Hu 2015). The audio is the convenience layer on top of a mask that would rank mid-lineup on its own merits.
A mask sits on facial skin every night; washing it regularly is hygiene, not fussiness. The Sound's electronics module pops out of the strap so the fabric machine-washes like any Manta — without that, a $149 mask you couldn't wash would be a non-starter. The cost is a maintenance routine a plain mask doesn't have: module out, wash, dry, module in, charge every couple of nights. Livable, but real — factor it into whether the audio feature earns its keep for you.
Price the Sound as two products and it makes sense: a premium blackout mask (~$89 by Manta's own Pro pricing) plus functional sleep headphones, combined into the only form factor that works on your side. For the nightly audio sleeper, $149 is a fair bundle. For everyone else, the math collapses: the Pro delivers the same darkness for $89, the MZOO for $26. That's why we mark it consider rather than buy — it's a superb product with a narrow correct audience, and outside that audience the premium buys nothing you'll use.
The Manta Sound is the rare gadget-ified sleep product where the gadget solves a real problem: falling asleep to audio when you sleep on your side. The flat in-strap speakers are the one form factor that survives a pillow, the ~24-hour battery covers real nightly use, and the mask underneath is a genuine Manta — 100% blackout, zero eye pressure, machine-washable once the electronics pop out. If white noise or podcasts are part of your sleep routine and earbuds have failed you, buy it; nothing else in the category does this job, and the TIME recognition is deserved. If that's not you, the price is the verdict: $149 for darkness the Manta Pro delivers at $89 and the MZOO approximates at $26, plus a battery to charge and a module to manage — and, per our standing materials criterion, a synthetic rather than natural fabric on your face. Superb engineering, narrow audience. Know which buyer you are before clicking.
