Iove my sbh50. I've had 2 in fact,thought I lost one and bought another. 1week later I found it left on with a full charge. Granted it was not connected to a phone and in stand by but even then I get about 10 hours with non stop streaming music and taking calls. Another plus is you can stay connected while charging. Which is great in the car. I also use it with an FM tuner that has 3.5mm plug and a head unit in another car with the 3.5mm aux, bookshelf speakers ect and it all works great. You can also pair 2 devices at a time and separate music and calls. In my car with a Bluetooth head untit I have the note 3 stream music not calls for privacy, and the calls only go to the SbH50 to earbuds. Alternatively you can have your phone connected for calls and another device, say your tablet connected for media.
