I am looking for headphones with decent isolation, zero sound leakage, a little emphasis on the bass, and they must be comfortable. I am willing to spend no more than $200 and perhaps I am asking a little too much for the price I am looking for. I had gotten Studio Beats as a Christmas gift two years back. They are okay but have terrible sound leakage so I disturb others around me when I am studying in the library or commuting on the train. Every headphone that I look up or that gets suggested to me has something majorly wrong with them. For example, The Shure SRH840s are heavy and have high treble. The AKG 550s I hear lack bass and although I have never tried them, I think they would be too big for my head. The ATH-M50s which are highly regarded on this site would be good for me but I do not like the permanent cable one bit. I do a lot of walking to and from the train station and around school so I am constantly get caught on stuff. My friend own the M50s and now has to get a replacement because his cable broke. This whole headphone search is getting very frustrating.
Here is some additional criteria that I am looking for:
•Source: I'll be plugging these into my ipod, laptop, etc.
•Isolation: I would like at least some isolation. (I understand that I would never be able to get complete isolation unless I bought a Bose or something but that's okay)
•Tonal Balance: I would like an emphasized bass but I don't want anything else to be buried.
•Past headphones: Apple ear buds, Beats Studio model
•Preferred Music: I usually listen to indie (Monsters and Men, Mumford and Sons), house/trance/etc (Infected Mushroom, Astrix), rock (Queen, Dropkick Murphys), and a little bit of jazz and rap.
