Hello Mr. FiiO,Phone calls and microphones of the UTWS5:
Either the left or right channel can be separately used for phone calls- single click the button of the ear hook to answer a call, while long press to hang up.
Both of the ear hooks have featured dual microphones processed by advanced CVC noise-cancelling technology. allowing the UTWS5 for clear calls with ambient noise restricted.
Best regards
Thanks you for the answer and the explanation. But is it the FiiO UTWS5's mics that are used for the voice or it's the smartphone's mic that are used for the voice when I spend call?
I'ld like to be sure.
