Manta SOUND Sleep Mask gives you complete control over the two senses that have the biggest impact on your sleep: sight and sound.
Designed for side sleep comfort, the ultra-thin Bluetooth® headphones are nestled within a ventilated strap — while the C-shaped eye cups ensure zero eye pressure and a perfect blackout seal without bulk.
The result: unmatched comfort as you listen to the sounds that soothe you — so you get the best sleep you're capable of.
Every detail designed for unbeatable side-sleep comfort.
Ultra-thin Bluetooth® headphones
SOUND Mask's ultra-thin Bluetooth® headphones are designed specifically for side sleepers.
Each speaker is as thin as a yoga mat — so you won't feel them at all, even when lying on your side.
C-shaped eye cups
SOUND Mask's C-shaped eye cups sit completely flat against your temple, providing zero eye pressure while delivering true 100% blackout — even when you're sleeping on your side.
Adaptive "air bubble" design
Our eye cups feature a smart “air bubble” that expands to block light when changing positions and compresses flat when side sleeping — giving you complete darkness with maximum comfort.
Perforated materials
Created with specialised perforated materials and innovative 3D-knit mesh for maximum airflow, SOUND Mask is engineered to keep you cool throughout the night — no matter how long you sleep.
It's the most comfortable Bluetooth® mask on the market.
Designed for light sleepers
SOUND Mask combines ultra-thin Bluetooth® speakers with 100% blackout to help light sleepers get the rest they deserve.
Listen to anything that helps you relax — from music to white noise and meditation — while completely sheltered from outside distractions.
20-hour battery life
Unlike most Bluetooth® masks, Manta SOUND Mask will never interrupt your sleep with battery notifications.
Double the battery life of competitors. Your sleep soundtrack plays all night long.
Infinitely adjustable design
SOUND Mask lets you fine-tune every aspect of your mask — from the tightness of the head strap to the position of the eye cups and speakers.
Unlike most audio masks, easy-pull tabs let you position the speakers exactly where you need them — even while wearing the mask. Simply pull the convenient tabs on the sides of your mask to position them just right.
Magnetic closure system
Manta SOUND Sleep Mask is easily washable, thanks to its unique 2-layer strap design.
Simply peel off the outer layer which houses the electronics, and machine wash the inner layer. Easy.
Partner-friendly audio
The optimised speaker design delivers clear sound directly to your ears while minimising sound leakage.
Fall asleep to your favourite podcasts, meditations or nature sounds without disturbing your partner's rest. So you can both enjoy your best sleep ever.

The mask’s battery lasts about 20 hours on non-stop playback at full volume (2x as long as leading alternatives). To preserve the battery, Manta SOUND features smart auto-off after 30 minutes of no audio.
And unlike most Bluetooth® masks, SOUND will never interrupt your sleep with a battery notification.
The head strap on Manta SOUND Sleep Mask is made of high-quality perforated foam and mesh, while the interior is made of soft Modal fabric.
At a normal listening volume level, your sleep partner will not be able to hear what you’re listening to.
Yes. Manta SOUND Sleep Mask’s Bluetooth® headphones are only 5mm — as thin as a yoga mat — so you can’t feel them at all, even when you’re on your side. And the C-shaped eye cups sit completely flat against your temple, so you can lie comfortably on your side.
Manta SOUND Sleep Mask is designed to fit every face type perfectly. Its spacious, C-shaped eye cups are tapered at the edges — and their position is adjustable for a flawless blackout fit.
The head strap itself is about 72 cm in circumference, and is fully adjustable as well.
The Bluetooth® headphones are also easily adjustable — even while you’re wearing the mask. Simply pull the tabs on the sides of your mask to position them just right.

The product didn’t suit me personally. But the customer service team were 10/10. I would like to try the other more basic eyemasks, as this one hurts my ears.

If you decide to explore other options, our Customer Success team is always happy to guide you toward the best fit for your sleep style.
I've had my sleep mask for years now, hopefully soon upgrading to the next gen, but this one is still great. Still comfortable after several years use, sound is still great, still 100% blackout, the Velcro isn't as tight as it used to be but still holds fine after several years of daily use. They're expensive but you'll get better sleep daily, well worth it in my opinion.
Hi Scott,
Thanks for the fantastic feedback! We're thrilled to hear your SOUND Sleep Mask has been delivering such consistent performance over the years—comfortable fit, great sound, and true 100% blackout. It's wonderful that even after daily use, it's still holding up well and giving you better sleep every night. We truly appreciate your loyalty and are excited for when you're ready to experience the next generation!
So comfortable and breathable. Keeps all the light out and I listen to my green noise. Changed the way I sleep.
I was never great at sleeping and this product has completely turned that around.
Thanks for the amazing review, Sean! We're absolutely thrilled to hear that our sleep mask has completely transformed your sleep experience.
It's wonderful that you're finding it so comfortable and breathable while effectively blocking out all the light for your green noise sessions. Sleep struggles can be so challenging, so knowing we've helped turn that around for you truly makes our day.
Thank you for sharing your experience and here's to many more nights of exceptional, restorative sleep!
I've utilized sleep mask before from other brands, they weren't bad, but this is the best, and well worth the money. The eye cups a plush yet firm, comfortable and removeable. The sound quality is crisp, clear and paired without a problem. Lastly the boot up and pair notification tone is so pleasant, no jump scares on or off. Just sweets dreams. One charge should last approximately 3 days.
Thanks for sharing, Christian! We're so happy to hear you made the switch and that the Manta SOUND Sleep Mask is exceeding your expectations. It's wonderful that you're loving the eye cups' comfort and removability, plus the crisp sound quality and smooth pairing. Here's to many nights of perfect sleep ahead! 😴✨
The sound on these is great and they are comfortable to wear as a side sleeper. My only complaint is that they slip a bit on my head, so they don't feel super stable.
Thanks for the feedback, Jennifer! We’re glad you’re enjoying the sound quality and side-sleep comfort.
For added stability, try fine-tuning the strap tension and using the slim strap included with the SOUND Mask, it can help keep everything securely in place throughout the night. If you’d like more tips, our Customer Success Team at support@mantasleep.com is happy to help.
