Looking for a headphone in the 100 - 200 euro price range, intended for indoor purposes only, and will mainly listen via my laptop or sometimes my Iphone 3GS. I listen to metal and trap/dirty south. In regards to metal, things like The Acaia Strain, Emmure... Regarding trap music, anything from the classic 3-6 to Chief Keef, Gucci Mane, Young Dolph. I also plan to use them for listening to movies.
I do like a tight bass for trap, but not sure if this would benefit my metal as well. The only headphones I've used in my life are some 20 year old Sennheiser HD 540 Reference II headphones, which are great for classical music. I have listened to Beats and must say they please me but I've heard there's much better stuff out there for that price.
I've been looking at M-Audio Q40's so far, but as this is going to be an investment for the next decade, I want to get as much options listed as possible.
