DT 770 PRO X

I see you've already said the Arya Organics are out of your budget, but I thought I'd chime in with my two cents anyways. A little bit of context, I also mostly listen to metal and rock of varying sorts. Ranging from Muse or Twenty-one pilots to Avenged Sevenfold to Paleface Swiss, but I'll sometimes venture into some pop, alt rock and rap too, as well as some soundtracks, mostly Hans Zimmer and some video game OSTs. I recently decided to be financially irresponsible and buy the Arya Organics as my first step into the world of planars. I had previously been using HD660S, DT 770 PRO X and my daily driver DT 1990 pro. And all I can say is wow. Just wow, they truly do sound incredible. I know some people can be quite sensitive to the Beyer's treble but that never really bothered me at all, and apparently some find the Organics too bright but that also doesn't bother me at all. In fact I think I quite prefer that. The bass on them is also very impressive for being an open back. The speed and clarity while still sounding exciting and fun is great. Although I love my 660S, they always felt quite flat and dull, and never had that slam and thump in the low end, but that's not the case for the Organics. It's the same reason the DT1990 became my daily driver since that was a more well rounded headphone imo. I haven't put any EQ on and don't really feel the need to. They truly are an endgame headphone and has quickly become my new daily driver cans. So although the Organics might be outside your budget (and rightly so lol) I'd still have a close look at the Arya lineup as they all seem like solid choices and should be somewhat similar, just pick one that falls within budget.
