works very well.
when I purchased I did not realise it is connecting through a USB port and it is an another soundcard.
though I found some good use out of extra soundcard with Windows 7.
Basically my original sound card on computer is for all the media stuff
Extra sound card (on Microphone) is used for communications, got seperate speaker hooked up.
I don't know whether everyone will find that useful but I think it is handy.
