Bia Smart Sleep Mask

Bía Sleep encourages your brain to transition and stay in a desired sleep state using Neurofeedback. This gentle guidance trains your mind to enter each sleep state faster. We use fNIRS to measure brain activity and bone-conduction audio to guide your sleep.

Bía Sleep can and should be used by individuals over the age of 19. It is not a medical device and is not intended for diagnosing or treating clinical conditions. If you have a health condition, speak to your doctor first.

Bía Sleep was created by side-sleepers, for side sleepers. It's made with soft, breathable materials and has no hard parts along the sides of the head — no unwanted pressure in any sleep position.

Access to all features upon release and any features added in the future — including Neurofeedback, Guided Meditation, Time Shift for jet lag, Bluetooth Streaming with Auto-Pause, Lucid Dreaming, and much more.

You can return Bía up to 60 days after you receive it for a full refund. That's two months to try it out and return it if we don't help you get a better sleep.

New orders are currently shipping April 2026. We'll keep you updated with monthly progress updates so you'll always know when to expect your Bía Sleep.

Premium includes everything in Early Bird, plus prioritized shipping (4–6 weeks faster) and access to premium color selections: Black and Blue in addition to Grey.

Remove the electronics by peeling back the medical-grade velcro, then throw the remaining layers in the wash with the rest of your laundry. Hang to dry. Super easy!
