If you experience background noise or intermittent audio during Bluetooth connection, this may be caused by interference signals in the surrounding environment.
Please try the following:
- Check the connection distance: In an open, line‑of‑sight environment without interference, the Bluetooth connection distance can be >20 m. Technical specifications: frequency offset ±25 kHz, sensitivity ‑85 dBm, BER ≤ 0.1%.
- Avoid strong interference sources: Make sure there are no high‑power electrical appliances nearby that may cause interference, such as Wi‑Fi routers.
- Try another audio source or media file: In some cases, the issue may be related to a specific audio source or media file.
- Try another phone or TV: Connect via Bluetooth using a different phone or TV to rule out compatibility issues.
