Tips:

1. For optimal performance, it is recommended to place the audio device in the right-hand pocket or right-arm pack.

2. Due to the human body signal interference, during the movement or large movement, the connection of the headphones may be interrupted, noise may occur, or the signal may be lost for a short time.

3. The transmission priority between the audio source and the right earphone unit is high. Under the interference of multiple Wi-Fi signals, the left earphone may be interrupted. It is recommended that the user should not interfere with the signal in other frequency bands such as 2.4Ghz. Use it to ensure the best wireless experience.

4. There may be a delay between the playback screen and the headphone sound signal on this unit.
