Oops, it seems my memory failed me this time. I thought that the headset shown above was a new AKG replacing their old GHS-1 but I'm confusing AKG with Plantronics. Sorry. The image is the newer Plantronics RIG system. It's still only stereo, it doesn't handle any form of DSP. I had wanted to hear the old GHS-1 but not at the prices Amazon is currently charging. You could pick them up much cheaper before they were discontinued.
