RE: New headset
I'm not quite sure what the headset audio quality is like, but I recently purchased a Logitech EasyCall pack from PCW for £25. Now, I was really just looking for a keyboard and mouse for my little sister as I'd built a new PC for myself, but this is a pretty damned good deal.
Basically, in the box you get:
USB Audio Thing
Basically, the USB Audio Thing is a big speaker, but it also acts as the wireless receiver for the mouse and keyboard. It also has two plugs on the side: one for the microphone, and one for the headset audio - they're standard 3.5mm jacks.
There's also a bunch of buttons for Skype integration, etc.
I have to say, it's one of the best things I've bought from PCWorld in a long long time.
