Abstract

A microphone can be provided on a charging case for wireless earbuds. This can be used for quality recording and microphone placement, as well as assisting in echo cancellation algorithms by measuring environmental noise. The microphone can be movably mounted to adjust for noise or echo cancelation on another device such as a cell phone.
