In Walkie-Talkie mode during calls, the earphones and Super Mic will automatically mute when the user does not press the call button on the charging case. Pressing the call button immediately unmutes Super Mic, and the call is conducted solely through Super Mic. Once the call ends, the device returns to default.
Walkie-Talkie mode can be enabled in the Nothing X app settings. When enabled, the device will automatically switch to Walkie-Talkie mode upon answering incoming calls.
