Its a Labtec right?

What is it about them? I get the same background noise I heard from you that first time.

I picked up the pair with the stereo head phones yesterday for $30 at BestBuy.

Now if I can just setup the 2 soundcards so TeamSpeak is only used by one of them I'll be super 1337 :P

TS says its possible:
Advanced (settings):
The advanced menu item has 2 entries. The first (Sound devices) opens a dialog box which allows you to choose between wave and direct sound in- and output drivers. Since version 1.05 you can even choose what sound device you want to output to. So if you have 2 soundcards, you can let your game sound go over one, and teamspeak sound over the other.
When other option (play notifications sounds) is checked, a sound will be player when you connect and disconnect from a server, and when new people enter your channel.
