How to Test the X1 with a PC soundcard: 

The X1 headset has three plugs at the end of its cable: 
- GREEN audio input
- PINK mic output
- USB power connector

If you're having trouble with your X1, you can plug it into a PC soundcard and
USB port to test it. 

- GREEN plug from X1 connects to LINE OUT or FRONT L/R (GREEN) on soundcard. 
- PINK plug from X1 connects to MICROPHONE jack (PINK) on soundcard. 
- USB plug from X1 goes to a USB port on computer. 

First play a sound file on the computer to make sure the headphone playback
works. 

Then try listening to your voice in the microphone to make sure that works
(you may need to unmute the Microphone in your soundcard's mixer software). 

If you can hear sound playback and your voice in the microphone, then the X1
headset is working.
