EPOS H6Pro Closed-Back Gaming Headset - Lightweight Over-Ear Headphones with Lift-to-Mute Mic - Compatible with Xbox, PS5, PS4, PC & Windows - Noise Isolation for Immersive Gaming & Streaming (Black) - Perfect for Competitive Gaming, Live Streaming & Online Meetings

I bought these used for 60$ used completely worth it because I’ll really only be using with the steam deck on flights where closed back is needed. I have the open back ones already and much prefer the sound stage on those. If you want zero outside noise and only hear the game. The closed back hands down are the ones for you. Less sound bleed on the closed back, so if you are gaming in a room while someone is watching a movie these don’t bleed sound as much as the open back.Open back: wide sound stage less bassClosed back: narrow soundstage more bass.These things sound identical to my closed back GSP but way more comfortable. The bass is noticeably crisper and less muddy, still has that “scoop” sound profile that all sennheiser/epos closed back headsets have. Mine had no rattling.Been trying a plethora of DAC’s and the GSX1000 adds the icing on the sound profile like I expected too. But other dacs such as the x4 do a good job as well. Little fat down low but the clarity is still there. They do sound great plugged into standard jack ports on my pc. You will experience bad sound quality if your device can’t drive these headphones. 280ohm impedance so keep that in mind when buying. Among the game series, GSP series, and the h6 series. These are the most comfortable of the 3.I like the open back better, the gsx dac really bumps the bass and makes the soundstage wide. Hearing distant skirmishes and artillery really feel distant with the open. You get a similar experience with the closed back but the difference is enough for me to chose the open back as my preferred headset.
