Works great with Nexus 7, 2013 and Galaxy s4. It's very simple to set up: the power cable to connect as well as the 2 RCA audio outputs of the box (cable supplied) to connect to the audio mini jack input of my amp (also work when connected to a mini Hifi). The Bluetooth pairing with the tablet or phone is very fast. Exactly what I was looking to enjoy music from the phone or tablet on my Yamaha amp. The sound is good (I'm not musical); we must increase the volume on the amp, but this does not pose concerns.
