Thanks for the help! I've gotten a better understanding about headphones now.

How many ohms can an iPhone take without an amplifier?

I prefer over-ear, and I mainly listen to top 40 and Hip-hop

Hello everybody!   I am new here and i know just about nothing about headphones. But i would like to buy a set of quality headphones, which i can use to listen to music on my iPhone at home or on the go. I figured people here must know a lot about headphone, so if you can recommend me...
