I faced an issue today and it confussed me.First at pairing mode the led was white(or pink)and the "bluetooth connected"(and "power on" etc..) voice dissapeared.The most wierd thing was that the volume sound when you get to max(that "beep")changed and it can be heard once and if you press vol up again it goes to min volume(the headphones volume-i'm using android),and another wired thin is that if i repeat that volume thing 3-4 times there are some wierd beeps and after that the volume blocks (and the other functions as well-play/pause etc)and i have to pause the music from the phone to turn off the headset.

Please help if you know any solution to this.(i think it might be be a firmware update,but it's just a guess).
