My headset randomly beeps.

My headset randomly beeps.
My Sony headset recently started beeping at random intervall, it is the same beep that Plays when I pause with the tuch/gesture control, but that recently stopped working. Somtimes it beeps 5 times in 3 seconds, and others it beeps once per minute. And the nc button does not work. The power button can turn the headset on, but not off.
