Kinda need some opinions on headphones. I listen to mainly electronic music( House, Dubstep, Trance) which is somewhat bass heavy and was wondering what a good pair around the $150 dollar price range would be. Been hearing the Sennheiser HD 518 might be the ones im looking for after alot of research on these forums. Ive also hear great things about the Grado SR 60i and they are cheaper so thats always a plus. Lastly people rant about the Audio Technica m50 but thats a little pricey. These would mainly be used without an amp and for listening to music on the go. Thanks for any help.
