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.

Sennheiser GSP 600 ( wired ) and GSP 670 ( wireless ) One and only. Nothing else matters

Hey das kenne ich und ich habe auch gerne meine Ruhe - daher Sennheiser GSP 600. Da kann auch deine Freundin hinter dir stehen und du hörst sie nicht. Es sehr angenehm zu tragen auch auf längere Zeit ist kein Problem, der Sound ist typisch Sennheiser super.

EPOS Sennheiser GSP 600 , they were 99 €and 102€ with delivery.  I don't think you can get those anymore. The headset itself works well but the cushions wear out every 2-3 years and the cable is firmly attached. When you put the headphones down and pick them up again it makes half a turn leading to cable issues every 5 years.   I'm sure if you make custom cushions with proper leather and a cable that can  somehow turn they would last  20-30 years if you don't drop them. They have an annoying 2.5mm jack for some reason(headpjone side) 3.5mm pc side. Very sturdy build compared to other headphones. The cushions are exchangable and the cable too obviously. I have had them for almost 6 years and my second pair of cushions will need replacement or fixing and the cable needs replacement. 

i would love more closed back design headphone like 620s and m4. i like the openback idea but, I live in a noisy neighborhood, so openback is a big no for me. i have the og gsp600 (before epos) and hd620s and im absolutly love them.

Wear glasses myself and can confirm Sennheiser gsp 600/650 are fantastic. However, recently upgraded to an Audeze Maxwell and holy shit. The sound quality is immaculate it was like hearing songs for the first time. Now everyone I hear a song I like I can't wait to hear it on them later. The stock cushions aren't bad at all but just recently got a set of Wicked Cushions for them and now they're absolutely perfectly. Wear them for literally hours and never feel extra pressure from my glasses. Plus a 80+ battery life means I can forget to plug them up sometimes and they're still fine for basically a whole week.
