Logitech ClearChat USB headset

Logitech ClearChat comfort USB headset is a nice piece.  I really believe in usb headphones and headsets.  They sound amazing, free of hard drive noise, and other audio imperfections you get from the standard headphone jacks on a PC.  Using the USB socket ensures a purely digital stream that is crystal clear and enables cool things like playback controls and volume control from the headset itself via the USB-HID mechanism.  HID stands for human interface device and is a way to add control to the mix.  Keyboards and things like that use HID.  But audio devices that make use of HID opens up many new application possibilities.

I can think of ways to make this experience much better.  How about you?

I bet the World of Warcraft and Skype faithful know exactly what I am talking about.  How can we make the PC audio experience better?
