The earphones on both sides of the FW3 can be used for calls alone, you can answer the call with a single click of the button, and hang up the call with a long press.
Each earphone adopts a more advanced noise reduction technology, and each earphone is equipped with a call microphone, equipped with a new generation of cVc8.0 noise reduction algorithm, which can effectively suppress external noise while maintaining clear calls.
