While not the most attractive cans for travel, I have come to love the sound of my pair of Grado SR 225 headphones. They are perfect for punchy loud music, possess a bass response which sounds very “tight” and are amongst the best-sounding open-backed headphones available at their price.
A couple caveats: the SR225’s really need to be used with an amp – devices like the iPod won’t be able to power the headphones effectively. A properly paired headphone amp will give the sound added detail, punch and authority. Being open backed headphones, the sound tends to leak to the outside, meaning your love of AC/DC will be shared with those around you.
