try charging it through the wall charger instead of the PS3(assuming you were charging it on your ps3) , also try different charger or USB cable if you have.
Correct me if I'm wrong, but the headset has to be detected as a mass storage device in order for it to charge properly. Try hooking it up to the USB port on a PC, or to the PS3 to charge it. And above all else, make sure it's plugged in properly. Don't be afraid to be a bit firm with plugging the cable into the headset end.
That's what I mean, the USB cable that hooks up to the ps3 is the new one I bought today that one that also charges controllers. I also tried charging from a wall USB adapter and nothing either.. Same thing jus the red light comes for 3 seconds and turns off.
If that's the case, you may have very well burned the battery out on the USB charger. If it's still under warranty you might be able to get it replaced. Call support and see if they can help you.
