Volume Control support on handsfree
I'm not clear on wether the HTC One actually supports 3-button wired headsets or not?
I have tried many headsets, and besides the PTT (push to talk) button, neither of the volume buttons seem to function.
Headsets tried included standard iPhone 3 button hands free, Sennheiser hands frees, amongst others.
Can anyone confirm or deny whether the volume controls on any wired headsets work with the HTC One?
