Hi, head fi! I'm fairly new to the world of headphones (and this forum!), but I'm looking for a pair of open-back headphones mainly intended for home use. Recently I bought a pair of HD 25's, and while I'm satisfied (and frankly amazed) by these headphones, the problem with these is that I find they get uncomfortable after a while, and have a very small soundstage. That's why I'm now looking for something that will complement these headphones a bit, by which I mean a pair of headphones that will sit very comfortably and have a large soundstage. Aside from that I am also looking for a headphone that sounds a bit more laid back, because sometimes I just want to relax while listening to music and the HD25 just won't let me. I mainly like the HD 25 for its presentation of rock/hard rock and electronic (even though it still sounds alright with everything but classical), and less for how it showcases jazz, blues, and soul So basically I am looking for a headphone that (and let me sum up everything I haven't mentioned yet here) - is open-back - is comfortable for long sessions - has a large(r) soundstage - has a laid-back sound - preferably doesn't cost more than $300 (excluding amp, if including one would make a noticeable difference, in which case what would you suggest?), but I can go up to $500 if you can convince me ^^ (- works well with jazz, blues and soul (and maybe the calmer rock songs)) (- Bass presence? I would like the headphone to have some bass presence (doesn't have to be rumbling or anything), since I listened to the HD 558 once and even though I loved the rest of the sound, I wasn't sure I liked the bass part. Not a requirement though, as I understand open-back cans aren't meant to have much bass emphasis, and the HD25 has this more than covered.) tl;dr: I am looking for the exact opposite of the HD 25. For about $300. Amp?
