Could I get some assistance? I thought about starting a new thread for this but don't want to risk abusing the forums.
I'm looking for a set of cans that are somewhat portable (ATH-M50 size or smaller), have excellent detail, and have a fun sparkle in the mids and highs. I'm not an audiophile. I typically listen to classical, female vocal (jazz), and a lot of strings at home, as well as some ambient/chill. On the go I listen to electronic, lounge, and some pop stuff. I've got AD700's for my strings at home, so this pair would be more for taking to work or the university (in my bag or briefcase) for casual listening but also for some casual vocal tracking (my wife sings) so decent isolation is essential. I'd like as much sound-stage as possible in this budget but I don't have my hopes up considering the other requisite criteria. Having the open AD700's has inflated my expectations in that regard. Also, I'm not a bass-head but my AD700's are void of low-range response so these new ones need to provide a respectable amount of bass.
Headphones I've listened to and my opinion of them:
Audio Technica ATH-AD700 - I own these for gaming and love them to death. I listen to live string performances - harp, cello, violin, symphony and they are superb. Love the sound signature except for the lack of bass, which forces me to be selective about the music I put in while I've got them out.
Sennheiser HD 280 Pro - Flat, and too boring for what I'm looking for right now. Probably excellent for monitoring though.
Shure SRH440 - Much more life than the 280s, and a step in the right direction. Not enough bass though, completely left off the low frequencies of my dubstep tracks.
Audio Technica ATH-M50 - A further step. Great bass response, and I like the detail for the most part, but I swear the mids are somehow being compromised by the prominent bass. Overall it's not quite what I'm looking for.
Bose QC15 - Crap
Also, since I will have these out of the house quite a bit, I'll need them to be efficient enough to be driven off of a laptop computer or smartphone, OR I'm not apposed to getting a portable amp but the combined price of the two must fit into my budget of $200.
My current inclinations:
Sony MDR-V6 + Portable AMP
or
Ultrasone HFI-580 or HFI 780
Please tell me if I'm on the right track or if I should be considering something else.
