Cons: Very poor build quality, not very durable (earpads came off after about a year), very little bass, start to feel tight across the upper part of the ear after about 2 hours, can be hot during the summer, mic not very responsive and requires mic volume to be adjusted to max on sound card to be heard.

Other notes: I've tried several USB-based headsets over the years that emulate 5.1 audio and without fail they have always had problems sooner or later. From games that would crash, overly sensitive mics, poor voice quality, poor build quality dying after a year, poor audio quality, or would cause the system to lockup I have yet to find a USB-based headset that was worth the materials it was made from. Maybe I've just had terrible luck but if I'm going to spend upwards to $150 for a headset it had better be very durable, good mic and audio quality, and comfortable year-round. The fustrating part is that not many 5.1 analog headsets exist which only reinforces the mindset that companies would prefer to cheap out with crappy emulated USB, bypassing those who have better sound cards, instead of putting out a nice analog one.
Current prospects for new headset: Turtle Beach Ear Force HPA2, Psyko 5.1 PC Gaming Headset, Sharkoon X-Tatic Digital 5.1, ROCCAT Kave
