asrto a50 wont connect or charge
my astro a50 are the third gen with the base station. the worked perfectly last night now the only light that turns on is the lightening bolt. when i place the headset on the station it blinks rapidly and when take them off it stops blinking and just stays on. throught that the power level or light on the headset doers not turn on. i have tried to hard reset them but nothing works.
