A:Answer Hi Tejas,
Thanks for your inquiry. Great news! These headphones have a built-in mic for calls. The headset uses omnidirectional microphones. You can talk without worrying about the position of the microphone.
Intelligent and intuitive, the WH-1000XM4 headphones offer further improvements to our industry-leading noise cancelation, exceptional sound quality, and smart listening that adjusts to your behavior and your location. Using the Sony Headphones Connect app, Ambient Sound Control lets you adjust the volume of background sound and gives you the option to allow voices alone to be heard. Meanwhile, the Equalizer lets you customize sound levels to suit your music.
Regards,
-Ralph
