I'm a little disappointed that I had to return a Creative Tactic 3D Sigma headset which I received not 2 days ago from Amazon. It seemed to completely distort my voice when on Skype with my team partner in StarCraft 2. I had previously just been using a pair of traditional music headphones along with the built-in mic on my iMac. So anyway, with that said: What are you using that DOES WORK! I would prefer something without the need for software (i.e. the Creative Control Panel needed to be on in the background), and I'm almost afraid of USB headsets at this point in favor of a straight analog 3.5mm plug set up. Ultimately I don't care what it is as long as it's SIMPLE and works great with the few games I have to enjoy on my Mac (namely, well, all things Blizzard). I don't need a lot of bells and whistles - just headphones and a good mic. Please share.
