[cronos ad]

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
