Budget - My budget is up to $170, preferably less
Source - I mainly listen to music from my iPod or iPhone and from my computer when doing homework
Requirements for Isolation - I'm mainly going to be using my headphones at home (I live with my parents and younger sibling) and sometimes outside. Isolation is preferred, but not a necessity.
Preferred Type of Headphone - Full sized or on-ear
Preferred tonal balance - I'd prefer an overall balanced headphone set, but if it's slightly bass heavy I wouldn't mind
Past headphones - I've only used Apple earbuds, so this will be my first real set of headphones.
Preferred Music - I listen to a wide range of music. These are some of the bands I listen to the most: AWOLNATION, OneRepublic, Eminem, Green Day, He Is We, Imagine Dragons, Maroon Five, My Chemical Romance, Owl City, Panic at the Disco, Plain White T's, Sky Sailing, Vampire Weekend, Fall Out Boy, The Cab, All American Rejects, and all kinds of classical music. Also, I listen to a little rap.
Location - I live in the US
I've been looking at various headphones, and a few that I've noticed were the ATH-M50s, ATH-AD700s, the Beyerdynamic DT770, and the Sennheiser HD25-1 II. I'd prefer if I didn't have to use an amp, but I'd be willing to get a portable amp.
