The dedicated Pause/Play button is fine when you only use it occasionally. But finding requires feel for the button, making frequent use awkward. Tapping the right earcup, in contrast, is much more convenient. Please consider adding a user-selectable option in the app Settings menu for how the right earcup touch control functions.
The first option for the right earcup touch control would function just as it does today. That is, 2-taps will launch the voice assistant.
A new second option would change the right earcup touch control to Pause/Play. One-tap for Pause/Play, two-taps to jump Forward, three-taps to jump Back. (The user can still press and hold the pause/play button to activate the voice assistant.)
