Sennheiser - HD 800 S

I've had 2 gaming headsets, first it was a Steelseries Siberia, then a Razer Kraken, but then I got to know someone at work who is into sound. He convinced me to buy a HD 650 and by god it was a different tier. It was so comfortable, but 5-6 years ago I've changed it to a HD 800, purely because the same friend sold it to me £500, pretty much half price and he took good care of them too.

you have both of me dream headphones (atrium and HD800s) so very well

I love the HD600, but the HD800S is basically my perfect headphone since I’m the most sensitive in the midrange and bass. On top of that the fit of the HD800S is perfect for my head and ears. I’ll never sell my HD600 regardless of what  headphones I get in the future but they might be swapped out as my dailies for open backs.

I've tried the HD660S2, it did not impress me compared to the HD800s, I auditioned them back to back. My reaction to the HD660s2 was something along the lines of "Better bass better imaging version of the HD6XX (which are a third the price)." My reaction to the HD800s was... well I had no words I was blown away and moved to tears.

HD 800S. Sometimes I forget that I have them on. They never get uncomfortable. The soundstage is so great that sometimes I forget that I'm not listening to speakers.

Exactly that. I was wearing them daily for more than two years, and I find it extremely comfortable.

Love my 1990s but they're sibilant as fuck. Listening fatigue sets in maybe 2 hours in and I either EQ it down or I swap to my HD8XX

I have the Raal SR-1a, the AKG K-1000, the Sennheiser HD800, and the Raal Magna (too poor for the Immanis lol). The Raal SR-1a can throw a slightly wider soundstage than the AKGs, but sounds better with the wings much closer to your ears. It’s the biggest soundstage of the above, though I prefer the sound from the Immanis in every way. If you’re really looking to get an experience larger than a headphone’s natural “headstage”, though, you need processing more than novel driver placement. Look into the “Smyth Realiser”. It is a headphone system with a wider soundstage stage than most speakers.

I have the older version of these and love them.

Yeah totally agree with that, but the turtle beach was insanely bad. I have Sennheiser open backs and while the bass isn't anything to write home about, it's not a noticeable thing.

Listen to some binaural recordings on the 800S. Amber Rubarth - Sessions from the 17th ward is my fav binaural album, as it gives such a massively wide holographic effect, and the room (which is a church) sounds crazy.

HD 800S I've owned and tried LOTS of headphones. Nothing is quite like it. Honorable mention to the 5XX series. 598SE, 560S, etc.
