Its cheap, I got my blue ones for 6 dollars, it sounds good consider, and it is very light weight.  I do not know why some people insist this pair is better than 50-100 dollar headphones, it's really not.  Nothing to write home about.  For their price, they are the best, but this pair can't hold it's own against the bigger boys.  

My main complaint is the bass.   It's alright I guess, but half the time the bass sounds extremely ****ty, which is not surprising.  Scrathcy, not defined, basically all overall the place.  

Overall it's good.  Good gym pair since it is dirt cheap.
