It really depends on the headphones and how loud you listen to your music. Other than that, I don't know much about that sort of thing. I got my last pair of headphones for $10 at a drug store, and they're starting to fall apart in places, but they still amplify stuff pretty well, considering I've had 'em for 5 years now. I'll be looking for another pair soon, but not earbuds. I can't stand those because they don't fit comfortably in my ears.
