Cant say too much about it. It does Exactly what it claims to DO. Connect with Bluetooth whatever thingy (in my case a iPhone 4S, Lumia 920 a, a Surface Pro 3 (the Surface is crystalized crap though), some low budget Toshiba tablet) and Transmits sounds. Sound Quality Seems good, but Im not in super premium segment with my sound system, so maybe its not perfect. I wouldnt know. But I got sold a lot of crap in the last years (did I mention the surface?) And this thingy is not that, so 5 stars.
