Last summer I participated in a project to design some intelligent earphones controlled with a mobile phone app. Sadly as a lot of projects that begin the product could not go till the end. Some screens of the app UX/UI design I did.
Mockup from www.techandall.com
Main menu and functions
All menus related to sound degree and volume were controlled with a touch weel screen (like the old ipod analogic whell, I alwais loved it!)
Heart rate, sleep quality ... and alarm programming.
Music screen selection for selecting what use to sleep and wake up.
