Steelseries elite prism - problem

[Tubas500]

Just got the steelseries elite prisms, althought the guy said they were broken, i still wanted to try to fix them. The lightning works, and it was automatically recognized in the steelseries software, but i dont get any audio, and the microphone doesnt work. Any suggestions would be appericeated. Thanks

Check the internal wiring, if it's broken could be anything really.
