WID:

I hate those "earbud" things that came with my ipod.

I purchased a pair of $15 open ear JVC headphones with behind the ear holders that actually stay on when I'm running, jumping rope, or hitting the heavy bag.

I'm very pleased with the purchase; being that they were very cheap, always stay on, and sound pretty good to. However, I don't have much basis for comparison.

The Apple store has a pair of Bang &O's that are like $150. (that seems excessive)

Is there really a significant difference in headphones that justifies this type of cost?

If one was interested in getting a "top of the line" headphone are there some that you have experience with and/or suggest?
