Yeah I did post some planars. They are big and are used by audio engineers who need the BEST sound. There is more to headphones than size for most people. They need to wear them, carry them, drive them. When sound is all that matters they end up big, because bigger ones sound better.
Sennheiser Momentum 4. I use them the most and they are the most versatile. Even though I also love my LCD X (too heavy though and not useful when others are around) and my Beyerdynamic DT 770 pro (they're great but they're wired so can't easily take them out with me unlike the M4).
Hey wait a minute, I've got an Empyrean II and HE1000 too! No focal though, just a humble LCD-X. Such a well rounded collection! I support this amazing collection
Right now, I'm using Meze Empyrean IIs for 2022 COD MWII. Depending on the month and mood, I may be using my HE1000, LCD-X, Moondrop Dusk, or Letshuoer Z12. I have specific EQ settings for all of them so that I can boost my ability to hear footsteps. In the past, I used a set of Meze Liric 1s and they were my favorite FPS headphone. With my EQ, the sound stage would close in and texture would disappear (idk why it happens on the Liric bc it never happens on my other headphones). This made footsteps really really easy to find. I want another pair in my life but I can't justify having a headphone just for fps gaming atm. Planning to play BF6 in the future. The audio sounds really good from all the streams I've seen.
I mean, I also started with Beyers and there is nothing wrong with them. I remember hearing them for the first time thinking the same. It was a pair of DT770. Then I grabbed a pair of open backs, the HD660s and was shocked on how good open backs can sound. I side tracked for a few months with all other variants, DT880, HD600/650 etc and eventually I stepped up to LCD-X. It was like getting into the hobby once again. I had my mind blown on how good headphones can really sound. After the LCD-Xs tbh I tried various amounts of ZMFs, listened to Hifimans, Mezes in shops but ultimately I found my one and done, the Tungsten and never looked back ever since. I'm coming up to my 2yr anniversary of owning them and not buying anything else. Point is, if you like them and think they sound good and they do everything for you, don't look elsewhere. Diminishing returns hit hard after the LCD-X so take care
From everything I have owned and heard, I would elect three headphones as my overall best and favorites: the DCA E3, the ZMF Caldera Open, and the Audeze LCD-4z. The E3s excel with raw precision and separation, the Calderas with spatial flexibility, tonal transparency, and macro dynamism, and the 4zs with bringing a bit of every trait together into one package. All of these need EQ to sound their best, the E3s the least and the 4zs the most, but even a profile relatively close to neutral reveals each to be amazing in their own ways. For anything below $1000 used, my picks go to the 2021 LCD-2 (and X), Moondrop Cosmo, and Sennheiser HD 800 (also all with EQ).
