Earbuds are uncomfortable for side sleepers and create a hygiene issue with extended overnight wear. Speakers in the room wake your partner. SOUND is a flat bone conduction speaker that sits under your pillow — your head rests on the pillow, the audio transfers through contact with minimal bleed to the room. You get the sleep-music benefit without the earbud discomfort and without disturbing the person next to you. Bluetooth from your phone or load audio directly via TF card.
Music under the pillow. No earbuds. No room bleed.
- BONE CONDUCTION UNDER THE PILLOW: the SOUND speaker sits flat under your pillow. When your head rests on the pillow, audio transfers through contact with the pillow surface — the bone conduction mechanism carries the sound to your ears through the pillow material. The result is personal audio that doesn't project into the room the way a bedside speaker does.
- 3W RMS DUAL FULL-RANGE DRIVERS: two full-range drivers at 3W RMS provide the frequency coverage for sleep music, podcasts, ASMR, and ambient sound. Not speaker-grade audio quality for critical listening — but more than sufficient for the vocal-range content that works for sleep onset and through-the-night audio.
- BLUETOOTH + TF CARD SLOT: stream from your phone via Bluetooth — Spotify, podcasts, sleep apps — or load audio files directly onto a TF card for offline playback that doesn't require your phone screen to be on. The companion app provides additional track and timer controls when you want them.
- SLIM METAL + PLASTIC PROFILE: the metal and plastic construction keeps the profile low enough to fit under a standard pillow without creating a noticeable lump. The slim form factor is the core design requirement for a under-pillow speaker — it's flat enough to not be felt through the pillow during normal sleep.
Familiar music and ambient audio before and during sleep onset reduces sleep onset time and decreases subjective sleep quality complaints across multiple sleep populations.

How audio assists sleep onset and maintenance
Intrusive thoughts and ruminative thinking are primary causes of extended sleep onset latency. Familiar, low-attention audio — sleep music, podcasts, ASMR — gives the cognitive system a mild engagement that reduces the bandwidth available for intrusive thinking without producing the arousal associated with stimulating content.
Consistent audio cues before sleep build conditioned drowsiness associations — the same sound environment that preceded sleep consistently begins to produce drowsiness on exposure. SOUND's offline TF card playback means you can use the same tracks every night without a phone screen on to trigger the response.
Room-fill speakers wake partners. Earbuds are uncomfortable for side sleepers. Under-pillow bone conduction solves the personal-audio-in-a-shared-bed problem — the audio transfers through pillow contact with minimal bleed to the room at moderate volumes.
For anyone who wants to fall asleep to audio without earbuds in their ears.
The podcast-to-sleep person
You fall asleep to podcasts but earbuds in your ears are uncomfortable after an hour and wake you when they fall out.
SOUND sits under the pillow — no earbuds, no discomfort, no falling out. Bluetooth from your phone or TF card for offline play.
The shared-bed audio user
You want to fall asleep to music or audio but your partner doesn't, and a speaker in the room wakes them up.
Under-pillow bone conduction keeps the audio personal — minimal bleed at moderate volume. Your partner sleeps; you listen.
The side-sleeper who can't do earbuds
You're a committed side sleeper. Earbuds create pressure pain against the pillow within 30 minutes — you've given up on in-ear audio solutions.
Under the pillow means nothing is in your ear. No pressure, no pain, no earbuds falling out at 2am.
The audiobook listener
You use audiobooks to fall asleep. The phone screen has to stay on for the app or you lose your place. The light disrupts your wind-down.
Load audio files to the TF card for offline playback — no phone screen required. The companion app handles bookmarking and timer controls when you need them.
The ASMR sleeper
ASMR works for you but earbuds make the tingles turn into ear discomfort by the time you fall asleep.
SOUND's under-pillow delivery carries ASMR audio through the pillow surface — the effect translates through bone conduction at close range without in-ear placement.
Slide under the pillow. Connect Bluetooth. Sleep.
Slide Under the Pillow
Place the SOUND flat under your pillow — slim side toward where your head will rest. The metal + plastic profile is thin enough not to create a noticeable lump through the pillow.
Slim Under-Pillow ProfileConnect Bluetooth or Load TF Card
Pair SOUND with your phone via Bluetooth for streaming. Or insert a TF card with your preferred audio files for offline playback — no phone required, no screen on during sleep.
Bluetooth + TF CardSet Your Timer and Sleep
Use the companion app or button controls to set a sleep timer. SOUND plays your audio through the pillow surface. You fall asleep; the timer cuts playback without waking you.
