These headphones are very nice! I've been using them for a few weeks now and overall they have exceeded my expectations, especially at this price point.
Overall they are very comfortable to wear, even at extended periods of time when gaming. The sound reproduction is very good, with a nice well rounded sound stage. Nothing is too overpowering (bass, mid, treble) - they all seem well balanced with just enough oomph to feel the gaming action.
Pros
------
The microphone sounds surprisingly good! I did recording testing with the mic in the attached video.
The earpads were very comfortable, they fit my ears well and provide great sound isolation.
They are lightweight, and not too heavy. Microphone position is good. In line volume/mic controls are well placed.
Audio sounded very good, both in gaming and music playback situations.
Cons
------
A very minor con is that the gloss black finish attracts fingerprints. I'm just nutty like that! :)
