I've been looking to purchase some higher end closed headphones for long school sports trips. I have some Grados, but the lack of isolation is a nuisance to both me and those around me. My taste in music consists of mostly rock and some metal music. Lightest being Mumford & Sons, heaviest being A7x, Metallica and Bullet for my Valentine. Bass isn't a huge deal, though it needs to be present.
Unless a different one is absolutely necessary, a Fiio E7 is the highest I'll go amp-wise due to portability and budget. So any suggestions?
