Dark enough. Quiet enough. Finally.
The room is never quite dark enough. The curtain gap, the standby light, your partner's phone. And even when the lights are off, the silence just makes everything louder in your head.
The Sound Sleep Mask blocks it all out — darkness and sound together, on your face, one button away.

FAQ+
Yes — the 3D contoured eye cups sit raised 5cm away from your eyes so no light gets in from any angle.
The speakers sit flat against your ears inside the mask — designed to be worn lying down, on your side or back, without discomfort.
Yes — it connects to your phone over Bluetooth so you can play anything. White noise, rain, a podcast, a sleep app — whatever works for you.

Reviews
"The soft and cuddly material seals completely. The sound is wonderful, I've had another one before. The mask, which was smoother, didn't have this comfort at all. I loved it."
Verified Buyer · Colour: Black"Came earlier than expected, tried it for a little bit and the inside feels cool, the speakers seem small and sound is amazing. I had a Bluetooth sleep mask from a different store and it doesn't compare in quality."
Verified Buyer · Colour: Black"Very comfortable, the sound quality is good, they block out light very well, ideal for a good rest. I really recommend them a lot."
Verified Buyer · Colour: Black"It's very good, it's very soft, you can adjust it to your size, it's not tight, and the sound is clear without distortion. It's gentle for sleeping and doesn't disturb the person next to you."
Verified Buyer · Colour: Grey"Great value for money. The sound quality is very good, you can leave it on without it bothering your ear or taking your attention away from your eyes."
