GSP 600

They're effectively the old Sennheiser Gaming One with some tweaks, which were, indeed, great headphones. No idea why Sennheiser stopped making them in favour handing most of the branding to drop and going about doing something else. I've got the GSP 600, PC38X and a H6 Pro - all these are similar and they're all great.

I agree completely, I got mine a week ago and I am so happy with them. I had SteelSeries Arctis 7+which absolutely sucked, terrible fit and super uncomfortable plus their software is garbage. I also had Sennheiser GSP600's and the Game Zero's which were better but completely blown out of the water by the HD560's. I paired mine with the BAM500 mic which is great but the cable is very short so I would suggest an extension if you get this. My ability to hear people in game has changed completely, distance as well as direction. My mate was joking last night that I must be using hacks as I could simply tell where people were like never before. He retracted that after I whiffed every spray and just died anyway.

I've had the GSP 601 for the last few years. Comfy, no sweat, sound good, mic connection has been playing up for the last few months and the plastic broke making one of the ear cups loose yesterday. Again, these are years old and well used. They're great imo but I haven't ever gone high end.
