Hello guys, i am very upset with this new device. The speaker seems to be working just fine. but something is very wrong with the mic. I think it is mute. I downloaded manual of HS03 vxx.. but that thing did not lead me to any solution. I pressed the volume up and down button simulataneously and held them for 3 seconds.. i heard the beeps.. but the mic is still dead.. what to do ..PLZ HELP ...
