What’s more, the internal battery provides a remarkable 70 hours of continuous use on a full charge, so, for all practical purposes, the music never has to stop! The ATH-SR30BT headphones are equipped with a mic and controls in the left earcup, making it easy to answer calls, adjust volume and handle music playback on smartphones and other devices.
