I bought these directly from SteelSeries at the same time as this drop. I would say these are defiantly a gaming headset designed and marketed to gamers not audiophiles.
THE GOOD: The "wishbone" floating suspension is a pretty good design feature. The cans are comfortable for long use. The mic is an interesting design. The controls for "inline mute" and volume are part of the cans (this is a smart feature, digging around for the mute is not always conducive to game play). They can be daisy chained and it comes with a bunch of different connection options.
THE BAD: A lot of proprietary connectors, don't lose them! The drivers are kind of muted, I'm not sure if this is because I'm using the simulated Dolby Surround without the "recommended software/ hardware driver," or if there is a burn-in time (doubtful). The mic I have been told sounds a bit tinny (once again see no driver and current config [TS3]).
THE UGLY: Mostly the price.
For most people these are not worth $200, however if you are playing games for 25+ hours a week they are super comfy and anyone can just pick them up and plop them on your head without much fuss adjusting the headband.
Other Notes: I had no issues with the "dreaded left ear" but you do have to have an above average knowledge of sound driver configuration in windows (especially if you have a REALCRAP [RealTek] audio driver) to get the sound balance right.
