Earbuds are awful, but if they fit correctly, sound great.
I can not stand to use them.
I found a Sony earphone set that hooks over the ear like eyeglasses and sits gently on the ears, very comfortable and don't fall down all the time.
Also, I found those 180-brand ear warmers at Target that had earphones IN THEM! Can you believe that? They are great. I actually used my iPod outside this winter.
