Mic Mode is a feature on iPhones that allows users to select how the microphone functions during a voice call, which can improve the audio call quality. There are three different Mic Modes on iPhones running iOS 16.4 or newer versions: Standard mode, Voice Isolation mode, and Wide Spectrum mode. Voice Isolation is the most useful mode, as it muffles distracting background noises that interrupt your phone call. Wide Spectrum mode causes the microphone to pick up all the noise around the user, which can be useful in certain situations. Standard mode is the default setting that Apple uses, which emphasizes the actual user’s voice during a voice or video call and allows some amount of background noise to get in.

To use Mic Mode, users need to be on a call and swipe down from the top-right corner of the screen to access the Control Center. Then, they need to tap on Mic Mode and select the desired mode. Mic Mode only appears when users are running an app that supports the feature, such as FaceTime, Zoom, Facebook Messenger Video, and so on. Its important to note that this feature is only supported on certain hardware, including iPhones SE (2nd generation and later), XR, XS/XS Max, 11/11 Pro/11 Pro Max, 12/12 Pro/12 Pro Max/12 mini, 13/13 Pro/13 Pro Max/13 mini, and 14/14 Plus/14 Pro/14 Pro Max.
