About this project
Many sleepless people turn to sound — studies show up to 46% use music, white noise, or ambient audio to drift off. Yet earbuds press painfully in bed, and speakers disturb partners. Traditional solutions create new problems.
SluTune Q2 answers with true dual-mode audio: inside a mere 11mm body sit both a bone conduction transducer and an air-conduction speaker, physically isolated, acoustically decoupled, and precisely tuned. Bone mode stays private through the pillow; speaker mode fills the room. A 2W configuration with a copper-plated aluminum voice coil massively upgrades the 0.05W first generation. Magnetic base, built-in hook, and TF card playback complete the package.
Launched in December 2025, it drew 1,546 backers and about $89,779 — roughly 2,993% funded.
Highlights
- ✓Dual-mode audio: bone conduction or speaker, no ear pressure when lying down
- ✓11mm thin: unobtrusive under or beside any pillow
- ✓2W upgrade: 40x the power of gen-1 for fuller sound
- ✓Offline playback: TF card support, no phone needed all night
