Troubleshooting
Common Problems and Solutions
- The headset can't be paired with the cell phone?
Check whether the headset is already paired or connected. Also, verify the Bluetooth search function on your phone is active and working.
- The headset cannot be turned on?
Ensure the headset has sufficient power. Charge it for at least 30 minutes before attempting to turn it on again.
- Can the headphones replace the battery?
No, this headset uses a non-removable built-in battery. It is not recommended to replace it privately.
- Can I use this headset while driving?
While possible, it is not recommended to use over-ear Bluetooth headsets while driving. Minimize the volume if you must use them.
- Headset disconnected with cellphone?
The effective Bluetooth connection distance is 10 meters indoors. If the distance between your phone and the headset exceeds 10 meters, or if there are multiple obstacles, the connection may drop. Keep within the effective range for stable connection.
- After the headset is connected to the computer or mobile phone, do I hear a different sound?
Bluetooth is a wireless technology sensitive to objects between devices. Check for metal or other objects affecting the connection within the range.
- After the headset is connected to the mobile phone, can the headset be used to control applications on the mobile phone?
Software settings of device applications may vary, and some functions of individual applications might not be supported by the headset.
Restore Factory Settings
If you encounter pairing issues or other persistent problems, you can reset the headphones to factory settings:
- First, delete the pairing information of "SANSUI" headset from your mobile phone's Bluetooth settings.
- While the headset is powered on, long press the Function Key for 5 seconds simultaneously to restore factory settings and shut down.
- After resetting, the headset's stored pairing information will be cleared. Please follow the "Bluetooth Pairing Connection" steps to reconnect.
Precautions
- Do not disassemble, repair, or modify the headphones for any reason. This may cause fire, electronic breakdown, or complete damage to the product.
- Do not place the product in environments with temperatures below 0 °C or above 45 °C.
- When the product indicator light is on, do not look directly at it and keep it away from the eyes of children or animals.
- Do not use this device during thunderstorms, as it may cause equipment malfunction or electric shock hazards.

- Do not place the device near heat sources or exposed sources of fire, such as electric heaters, microwaves, ovens, water heaters, stoves, candles, or other places that may generate high temperatures.
