About this item
- 【For Multi-room Indoor Audio】Designed for homes, classrooms, offices, and meeting rooms needing the same audio across multiple speakers. Ideal for background music, TV sound, and spoken content with consistent room-to-room coverage.
- 【Ultra Low Latency Under 30ms】Delivers synchronized playback with under-30 ms latency, keeping audio aligned across all speakers. Speech and video sound natural with no noticeable delay or echo during shared listening.
- 【Simple Setup, No App Required】Connect the transmitter to your TV, phone, or laptop via optical, AUX, or Bluetooth. Power on and speakers auto-connect with no app installation or complex setup steps.
- 【Not For Large Outdoor Venues】Not designed for large outdoor spaces or very loud environments due to limited maximum volume. Best suited for indoor use where clear, synchronized audio coverage is required.
- 【Limited Microphone Input Type】Not compatible with USB mics, direct XLR mics, or 3.5mm TRRS headset mics. Requires line-level output (3.5mm TRS or RCA) from a powered mic, wireless receiver, or mixer.
