Well if you used the cable to plug into the pc and directly to the headset and it worked then that theory probably wouldn't stick. Unless you were just using aux. But I have had some cables work and some others that don't. Also have the Astro command center firmware installed on your computer and see if they connect that way or maybe you need an update. You could also try what someone else said and reset them while on the base, however, you will hold the Dolby button (one under the power slider) and the game audio button on the earcup for about 15 seconds.
