5 out of 5 eggsGreat Headphones

Pros: These In Ear headphones are great! The bass is not so loud it drowns out the treble and mids. Very comfortable fitting design and is plenty loud. Comes with case and different ear canal sizes for any size person big to small.

Cons: The price is a little hefty but if you would spend 200-300 dollars on an mp3 player and use 5 dollar in ears for it then your not getting your money's worth in the first place
