"Great for running and working out."3.0 starson by kodre
Pros: Best fitting sport headphones I have ever used
Cons: Sound quality is poor for such a well designed headphones
Summary: In the end I would rather have to frequently adjust better sounding headphones that do not fit as well than to have poor sounding, well fitting headphones. If you decide to buy these headphones, buy them from a store that will accept returns, so that you can "try them out" first. I have owned headphones with a lot less quality sound, so the the MX 75 headphones may be significant upgrade and you just can't beat the fit. Lastly, the ear bud headphone I am currently using came from a Creative Muvo Micro N200, and them have some of the best bass I have ever heard to come out of bud style headphones.
