Understanding white and ambient noise during calls on noise-canceling headphones using Sony's Sidetone feature

Have you ever heard someone talking excessively loud while wearing their headphones? It's often unintentional, as your voice might sound different than you're used to due to the physical sensation of the headphones on your ears and the noise isolation they provide.

Sidetone helps us identify at what volume to communicate by relaying the sound of your voice through the microphone and back into your ears. By hearing yourself speak, you avoid talking overly loud. However, an active mic means that ambient or white noise can occasionally find its way into your headphones, especially in noisier environments.

Sidetone only activates during phone calls, so it's normal to experience reduced Noise Cancelling and louder ambient sounds or white noise compared to when you're listening to music.
