hi, i recently decided that i need a new pair of cans. However, i cannot decide what to get. I listen to  a wide range of music so i need  headphone that is good all around. My current headphones that im using is the Denon ahd 5000 and the Shure Se215. I love the bassyness of these cans but however i beleive that i need a  change. What im looking at right now are the Grado 325i, Grado Rs2i and the Heir audio 4.ai and 3.ai. I really want a headphone that will run well without a amp because i will be carrying these new ones around. The bleed in sound is not a issue FYI. Also it would be great to keep the price under 500. Thank you in advance
