The box works so far very good. What I like very much - I turn the box side of the on / off switch on - and a few seconds later it is reliably coupled with my iPhone, the confirmation buzzer an unmistakable sound as confirmation. I go on my iPhone to pause because I'm doing something else, for Bs -.. It takes a few minutes, and the box will turn off by itself, it then goes to standby. I have the box on the bed are in the dark room - and can, in complete darkness Bs ability to sense the keys -.. The middle button, the 3rd button from the right and left - I press on it, the audio playback will stop on my iPhone. The entire switching operations in conjunction with my iPhone work completely reliably.
The volume of the box is good. The sound of the box is well so far - acceptable for a device in the sense of Basic Standard device.
It's great, I also think that iOS 8 on the iPhone I can see the battery level of Bluetooth speaker - tip.
