Designed for audio during rest without wearing earphones
The SMB-03 uses bone conduction to transmit audio through vibration, placed beneath the pillow rather than worn in or over the ear. The 128×54×18mm profile fits under a standard pillow without creating noticeable bulk. Bluetooth 5.2 connects wirelessly within 10m. The 900mAh battery delivers 20 hours of playtime at 80% volume and charges in 2 hours. Three drivers (8Ω/2W×2 + 4Ω/2W) cover 20Hz–20kHz. TF card playback supports lossless formats including FLAC, APE, and WAV. White noise audio is pre-loaded. Certifications: CE, CE-RoHS, FCC-ID. Curated by Aetheo.
Key features
Bone conduction technology — under-pillow placement
The SMB-03 transmits audio through bone conduction vibration rather than a traditional speaker cone. It is placed beneath the pillow, and audio reaches the listener through the pillow material via physical vibration. The device does not need to be worn on the body — it operates from its position beneath the pillow.
Bluetooth 5.2 — 10m transmission range
Bluetooth 5.2 provides a stable wireless connection to smartphones, tablets, or other audio sources within a 10m range without obstacles. Supported Bluetooth profiles: A2DP 1.0, AVRCP 1.5, AVDTP 1.0, AVCTP 1.4, HFP 1.5, GAVDP 1.0. Bluetooth audio decoding: SBC.
900mAh battery — 20-hour playtime, 2-hour charge
The 900mAh battery delivers 20 hours of playtime at 80% volume on a full charge. Charge time is 2 hours via DC 5V/310mA. Working voltage: 3.7V. Standby time is ≥100 days when the device is powered off.
TF card playback — FLAC, APE, WAV, MP3, WMA up to 32GB
The SMB-03 accepts a TF card up to 32GB for direct audio playback. Supported formats via TF card: MP3, WMA, FLAC, APE, WAV. FLAC, APE, and WAV are lossless or uncompressed formats suitable for higher-quality audio files. White noise audio is pre-loaded on the device. Three drivers — 8Ω/2W×2 + 4Ω/2W — cover a frequency response of 20Hz–20kHz.
128×54×18mm — CE, CE-RoHS, FCC-ID certified
The 128×54×18mm body in ABS keeps the profile slim and low under a standard pillow. Certifications: CE, CE-RoHS, and FCC-ID — all three confirmed in the source specification table. Suitable for home, dormitory, and bedroom use.
