So I need recommendations on some preferably closed back headphones under $300 but it would be best if they were under $250 especially if they require an amp. I'm relatively new to the audiophile world and I want a new pair because I recently found out that my m50's were fake (after having them for a year and thinking they were the best thing ever). I have been looking at some choices such as the Beyerdynamic DT-770's or the Fostex Mad Dogs (I think that's what they're called).. I'm into stronger bass and good vocals but not ear splitting highs. I listen to mostly rock/alternative but I'd like something that could also be well rounded! As for an amp I'd rather a pair that could do without one, but if it's worth getting that pair + an amp I need recommendations on a portable amp and if it could be used while charging that'd be even better.
Thanks for the help!
