LCD-X and Focal Clear OGs are my highest-end headphones right now. The LCD-X are just too heavy for all day use, so I'm selling them. Love the bass though. Have played around with some JM-Mod HE-R9 headphones which are fun head rattlers and super comfy. Also have some HarmonicDyne Zeus that I switch to when my head gets tired of being crushed by the Clears. Had some AKG K702 special editions back in the day that cost more, but that's because I bought them in Thailand while living there and import taxes were insane, but were great for the competitive gaming I was doing 10 years ago (read: sucking at Battlefield 2 I think it was). The price difference between HE1000SE and the used Sussys are close enough that I'm not too bothered by it (along with other things I've considered like DCA Stealth/Expanse, Empyrean 2, Arya Organic/Stealth, HEK Stealth, HD800S). I've been through multiple Schitt stacks, a Topping stack and a Fioo dac/amp or two. I have my own
proper 7.3.4 home theater (well almost proper - it's a rental), but that's in the basement while my office is on the 2nd floor. So I've got about 10+ years in the hobby as a casual, but have started taking it more serious in the past year as I look for one pair of headphones to use as a daily driver for "everything". I'm not a big fan of switching headphones a lot.
Use case is immersive gaming (non-competitive games like RPGs, Cyberpunk, Skyrim, Elite Dangerous, etc), movies when I'm too lazy to go into the basement, and all genres of music. A lot of female Asian pop/rock, orchestral video game music, and all those other alt/pop/punk-rock songs 30-some year old millenials used to listen to 20 years ago (Linkin Park, Green Day, Coldplay, Paramore, The Offspring, blah blah blah).
I do not know anyone near me in the hobby, no one on marketplace has any for sale to demo, and the only two hifi stores within a few hours of me (that happen to be two miles apart) only carry a pair of LCD-2Cs and then a bunch of Grados. Why only Grados?! And why are the only two competing hifi stores 2 miles from each other only carrying Grados!? I supposed one of the has B&W headphones, too, but an actual B&W showroom is only 15 miles away. Super frustrating.
