I work in a shared office. I need full-sized cans that isolate well enough to not annoy my officemates. My JH13 is too annoying to keep inserting and removing throughout the day. My brand-new Denon D5000 leaks too much.
I like transparency, high resolution, and full-range reproduction. I don't care about fashion. As a reference point, I really like the JH13 except that the bass is unnaturally weak. (I got them before the JH16 existed.) I listen to all genres of music, but I've always found classical to be the best genre for separating truly excellent audio gear from the merely good. I've come across headphones that are brilliant at trance music and wither when I put Guerre-Lieder through them. Assume I have a good enough amp.
I've been doing some research, and it seems like the only real contenders are the Beyerdynamic T5p, the Ultrasone Signature Pro, and the Ultrasone Edition 8. Yet there seem to be significant concerns about all three of those -- enough to make me not even want to bother.
Does there exist a truly excellent non-IEM headphone that doesn't leak sound?
What would be the head-fi consensus for the best all-around choice that will stand up to full-scale orchestral/choral works?
Among the T5p, Sig Pro, and Ed 8, is there one (or two, or three) that I should not even bother trying?
