Yes, you can make and receive phone calls while using the P100. The headphones use Qualcomm’s cVc (Clear Voice Capture) technology and two dedicated communication microphones which will allow your voice to sound clear when making phone calls.
You will be able to accept and reject incoming calls and end a phone call using the button functions on the P100. A full list of the button functions can be found here or in the User Guide in the Melomania Connect app.
