This product is really very good dune +++ Lampl is very beautiful, powerful sound, there is radio, you can also plug a USB key, and above all there is the handy Bluetooth I will use that with my cell like that no need thread! There is also a built-in battery so you can use it without connecting it and the autonomy is very good. For microphones are really very good, do not distort the voice, great for me singing!
