SleepSphere is not a thin speaker. It's a declaration of sonic independence.
Using cutting-edge bone conduction technology, sound is transmitted directly through bone structure, completely bypassing your eardrums. This means clear, immersive audio for you, while your partner enjoys absolute silence. The ultra-slim design (11mm) disappears under your pillow. Battery lasts up to 28 hours. Smart software automatically turns off after 2 hours of inactivity.
It's not a speaker. It's architecture for sound.
SleepSphere uses bone conduction a technology NASA developed for astronauts to transmit sound directly through your skeletal system. Unlike traditional speakers:
It's engineering that respects human biology.

I work as a freelance copywriter and often write in the evenings with ambient music. Headphones cause discomfort, traditional speakers wake my husband. SleepSphere was the perfect answer: I listen in high quality, he sleeps undisturbed, zero guilt. Bonus: the 28-hour battery means I also use it during the day on the couch. It's not just a sleep speaker it's a productivity tool I've always wanted.
Sound never leaves your private zone. Crystal-clear audio for you, total silence for those around you. Listen to whatever you want, whenever you want no negotiations.
11mm thick, 48g light. So discreet that after one week you'll forget it exists. Back sleeper? Side sleeper? Fetal position? Completely irrelevant.
28 hours from a single charge means sleeping 4 complete nights without thinking about recharging. For travelers, this is true freedom.
If you suffer from insomnia, nighttime anxiety, tinnitus, or simply have a partner with different sleep schedules this is designed for you. Not a compromise. The solution.
Every night, you face an impossible choice: listen to what you love or let your partner sleep.
Headphones hurt. Earbuds cause pressure. Speakers disturb. And silence? It's too silent.
In 2026, we still sleep like it's 1980 without true innovation.
Until now
Imagine forgetting your speaker exists. You won't feel pressure, discomfort, or bulk only sound.
SleepSphere is thinner than a credit card, lighter than a pair of glasses. It's designed to disappear, letting you move naturally, sleep as you prefer, live without compromise.
A single charge covers nearly 4 complete nights. Intelligent auto-shutoff preserves battery while you sleep. Can't remember the last charge? Doesn't matter. SleepSphere is always ready, removing energy anxiety from your daily responsibilities.
Freedom means forgetting technological constraints.

Traditional speakers push sound through air to your eardrums. Bone conduction bypasses your ears entirely, transmitting vibrations directly through bone. The result? Nobody around you hears anything. You hear everything. It's audio privacy by design.
You might notice gentle vibrations for the first 2-3 nights, then your brain adapts completely. Most users report it becomes "invisible" after a week. You only notice it's there if you look for it.
Yes music, podcasts, audiobooks, white noise, meditation apps, everything. The technology reproduces all frequencies clearly. Your content determines your experience, not the device.
This is actually where bone conduction excels. Because it bypasses your ears entirely, it's ideal for people with tinnitus, ear sensitivity, or auditory canal issues. You get audio without ear pressure.
Practically nothing. The bone conduction transmits sound through your pillow, creating a "dead zone" around you. Your partner experiences complete silence unless they place their head directly on your pillow.
Up to 28 hours of continuous playback on one charge. For context: sleep 8 hours nightly, and you'll charge roughly every 3.5 days. Most users charge weekly out of habit.
Not waterproof, but moisture-resistant. Light sweating is fine; avoid heavy moisture. It's designed for your pillow, not your gym bag.
The device only auto-shuts off after 2 hours of inactivity. If you're actively listening, it stays on. The feature prevents accidental battery drain when you fall asleep.
Absolutely. Some users wear it under a pillow while working, meditating, or on flights. Any situation where you want private audio works perfectly.
USB-C cable (included). Full charge takes approximately 2 hours. Modern, reversible, and widely compatible.
