i am buying a nexus 7, which i hear has pretty bad sound quality. i understand that bluetooth audio would bypass the built in DAC. i am searching for a bluetooth reciever that is battery powered. it does not need to have an amplifier, as i can easily hook up my fiio e6 to amplify, all i want is a package that is not massive, and a decent DAC, and preferably Blutooth 4.0. i would also like it to get good battery life, preferably 16 hours or more. for reference, i will be using this with audio technica m50 with beyer dt-250 pads and removable cables, if that helps

Bluetooth audio is lossy (and audibly bad, last I checked).
