1) Ensure the earbuds are worn correctly and are not covered by hair, cap, hood, scarf, mask straps or helmet during the call.

2) Strong wind or a very noisy surrounding can cause disturbance during calls. Move to a calmer spot or turn away from the wind.

3) If the other party hears low or broken voice, check the network and the other party’s device.

4) Please once reset the earbuds and reconnect if the issue persists.
