at the beginning I would have put 5 star sound I find perfect for my taste of good coffee but after a week of use I started to have problems with the noise there was sizzling when he was there too low hissing when touched with headphones or with very unpleasant vibration or movement listening so I made a request for return I received it yesterday, now I have another problem when I ' no lights usually sounds a voice tells us the speaker turned to nothing when I connect my mobile phone bluetooth I do little more control music with headphones as if the button does not work, then suddenly it works after no more walking short I am sorry I think requesting a refund and I would point me to AKG as my old helmet that made the soul I will probably take the k845 BT ...
