I just recently got a new rig and am on the market for a great headset in the ballpark of $250-300. I am looking for something with noise-cancelling, amazing sound quality, and a clear microphone. I would go for a headphone/ dedicated microphone setup if they are built for gaming, the only thing I do on this computer. I've been looking around for some time and have been interested in the Sennheiser products and astro's A50s. I am pretty new to head-fi as well. I am unaware if this is important, but I am using an onboard sound card. Thanks!
