Nice quality sound bar. Goes loud enough for a speaker of this size, bass is decent enough for the size of this sound bar. Solid construction, feels nicely made. Rotational volume knob is a nice touch. The best feature of this sound bar however, is the bluetooth range! I have never had a speaker work so flawlessly so far away from my phone. Unit runs of flash card, bluetooth or 3.5mm AUX cable input. Unit will operate while charing, which is a nice touch.
