what's your budget? While not cheap, the Astro A40 Headset is godly, very comfortable, sounds great and has one of the best mics I've heard. Not USB nor wireless, and is $250 bucks, or $200 without the amp. I just ordered the Plantronics 377's about 5 minutes ago. They're decent, I got them for a steal so I jumped. The Plantronics 777 are comfortable and have a USB connector. I think the "hurting your head" varies from person to person. This was one of the reasons I was looking for reviews of the 377's before I ordered (I have a large head lol) I only found a couple that commented on comfort level. Like 2 said they hurt to wear and would feel really tight after 20 minutes, 3 said they could wear them 6 hours with no tightness. Who the hell do I believe? I ordered them and hope they either don't hurt, or it's not enough to bother me.
I wanted the Astro A40's but the price is well out of my range for now.
