Check your cable. Does it have a built-in mic?
Wyze Headphones don't include an AUX cable with a built-in microphone. If you're using the headphones plugged into another device, like a gaming console, you must use a cable with a built-in mic.
The included 3.5 mm "TRS" or tip-ring-sleeve cable does not have a microphone. You must purchase a third-party "TRRS" (tip-ring-ring-sleeve) cable with a built-in microphone.
