Saw someone mention this on Whirlpool, so I decided to check it out myself. They're PC only, so they're no good for Xbox or PS3 users. I don't know how good these are sound-wise, but TDK is a good brand and $5 isn't a lot of money, so even if they're absolute rubbish, it's no big loss. They'd be more that good enough for Skype/Msn.
It's my first bargain submitted here so be nice. Please don't start a Dick Smith flame war or anything.
Edit: Turns out that Dick Smith have started their online sale a day early, so there's a whole heap of discounted games as well.
Update: Deal has expired, so it's been marked as such
Damn! I'm no elf, the headset is small! and is not deep enough to cover my ears! cant use it too long! hope it fits my girl friend's ears!
And yes it has static when used with USB but not with batteries.
