This is a concept for a mobile HiRes Music Player for audiophiles, with essential functionalities and easy to use. 

The idea is that it could be developed as mobile app for iOS and Android smartphones but also for Android-based HiRes portable players.

Here you can see the preliminary drafts, manually sketched on paper. I love to use pencils and markers to explore and define ideas quickly and freely.

Below you can find the final UI Design that show how the app appears with real contents.
