I currently have the SteelSeries 5Hv2 paired with a Razer Barracuda AC-1. For gaming it's great but I find it's lacking for music. However, I find that this is probably the most comfortable headset that I've ever used, I've gone on all day wearing it without any discomfort. As for comparisons, I've used a Steelseries Siberia with the X-Fi Fatal1ty edition and I prefer my setup over it. I've never used the Sennheiser so I can't really say anything about those. But from what I've heard they are better all around.
