I recently bought the cronos ad headset and when I say recently i mean yesterday it arrived i opened the package this morning plugged them in and they didn't work what should I do? by the way I have set them to default,I updated drivers,I tried to disable and enable them,I even restarted my computer,I replugged them in The only thing i can think of is either a) the headphones are broken b my computer is broken Edit: I think its from the headphones i plugged them in my phone and they still didn't work
