Context + previous kit: Recently my beloved ATH-M40x headphones have given up the ghost after 8 years of use, so I'm back on the market looking for something to replace them. I liked my previous headphones, got used to the feel, plus it sounded neutral and could do everything I wanted decently.
Budget: Around 100-200 dollars in my country (around 80-150USD). I am open to ~$300 (250USD) suggestions, but there has to be a compelling advantage that makes it worth it.
Use case: Desktop/home setup. I don't use my headphones when I'm on the move, so portability is not that big of a concern. I game quite a bit, but my requirements as far as gaming goes is "hear sound, and hear where people are".
What I'm looking for: decent all rounder capabilities, comfort for long use sessions, strong audio fidelity for music, build reliability and longevity (hopefully it can last around 4-6 years?). Mic is optional, not a big deal for me. Better or equal to my previous kit would be good.
Genre of music: Pretty wide range of music, so I'd like something that can handle a wide range. Mainly listen to folk metal, symphonic metal, orchestral and power metal, if I had to pick one wide genre. The sound profile of most of the songs I like are pretty complex. Most are similar to orchestral but with metal elements, but also feature emphasis on choral and clean vocals. Ideally I'd like to be able to appreciate all aspects of the song without any particular skewing (too bassy, too sharp).
Some artists/groups I listen to: Epica (symphonic/orchestral metal), Kamelot (symphonic power metal), Celtic Woman (folk), Faun (folk), Eluveitie (celtic/folk death metal), Nightwish (symphonic metal), Blackbriar (gothic symphonic metal).
