Hello everyone, I am going to be as objective as possible so not to take a lot of your time. BUDGET: $90~$130. GENRE: Classical, Instrumental (like OSTs, Yann Tiersen, Joe Hisaishi, Ryuichi Sakamoto, etc.), Rock (lots of styles, except for metal, thrash, death and similar), Folk, Jazz, Blues and a little pop. CAN BE AMPED (I have a Fiio E10). CLOSED BACK (Use at work with noise from refrigeration system, so no sound leakage and some sound isolation). COMFORTABLE AND GOOD FOR LONG USE UNDER MILD HEAT (25C~29C/77F~84F when A/C is off). OPTIONALS: Detachable cable / Collapsible. Source will be a MacBook Pro hooked to the Fiio E10. I was thinking about the ATH-M50s, but I have no way to try, plus it seems to be a little uncomfortable and not good to use under heat (due to sweating), although these are just my conclusions from reading other people. So do you guys have any other good recommendations? Oh and I own a Sennheiser HD598 and I like it very much. It can feel sometimes a tad bright and the bass is a bit lacking (I am not a basshead but I miss a little for the timpani, double bass, cello, etc.). But overall I really enjoy it, just so you know what kind of headphones I like. Unfortunately I am a poor student with no money to buy expensive equipment. I would also like to say that the recommendations thread is too messy and it's impossible to get a good recommendation in it. Too many people post there, so unless you spam the thread you won't be heard, to me that's just complete chaos. I tried twice using it and only got one good, but not very helpful, response. Thanks in advance and I hope someone can help me make this very important decision. ps.: I'll check the sound power of the refrigeration system I'll be working with and post it later.
