Description
SpaceBuds true wireless (OTW-630)
The OTW-630 SpaceBuds deliver up to 50 dB hybrid noise cancelling, an 11 mm dynamic driver with HavyBass™, customizable voice prompts and lighting, and Smart Chat Mode—wrapped in a lunar-eclipse-inspired transparent metallic finish.
Look and materials
Transparent and metallic 3D flowing surfaces aim for a lightweight “flow illusion” echoing moonlight and shadow. The charging case uses a metallic finish with a scratch-resistant shell; stems wear vibrant color coatings.
Personalization
Record or select custom voice prompts for status cues. Pick lighting colors in the app, including effects that can follow your music rhythm.
Smart Chat Mode
When the buds detect your voice, they enter Transparency mode and pause playback so you can talk without manually stopping media. Enable the feature in oraimo sound. Chewing, swallowing, coughing, and similar sounds may also activate it.
Audio hardware
An 11 mm dynamic driver with TPU+PEEK composite diaphragm and CCAW voice coil emphasizes low-end punch while keeping highs articulate. Hybrid ANC reduces external noise by up to 50 dB.
Controls and calls
Wide area tap responds away from the stem: double tap pauses or plays; triple tap cycles ANC modes—set up via the app diagram. Four microphones and AI call processing help keep your voice intelligible in noisy places.
Multipoint and gaming
Stay linked to two devices simultaneously. Immersive Game Mode lowers latency and applies tuned gaming EQ for tighter picture-to-sound timing.
Google pairing
Google Fast Pairing with pop-up notifications works on devices running Android 6.0 or newer with Google Play services.
Protection and hygiene
Earbuds meet IP54 (IP5X limited dust ingress without harmful deposits; IPX4 resistance to water spray from any direction). Antibacterial eartips are included to help limit bacterial and fungal exposure risks.
