I’m new to the headphones world and i need your help! I’m a stating audiophile (sounds funny I know :D) and i have really hard times choosing myself a good pair of cans. The place where i live there is almost no good headphones, so i can’t try out anything myself and i don’t have any experience with headphones.This is why im have to order it from internet shops like amazon(and of course get it shipped but thats nothing to do with my problem). I listen to hip hop, rap, i enjoy good bass, but i think getting cans with too much bass will give me a wrong idea about the how a good pair of headphones must sound like. My price range is 250-350$ and i was mainly thinking about Beyerdynamic DT 990 but got to know that those need an amp (which im not at all planning to buy). I mainly listen to music on my iPhone 4s/iPod. Is it possible to get a decent sound quality without an amp on iphone? Sorry for this mess and thank you.
