Summary: The pros and cons tell the gist of it. I love these earphones but some of the music I listen to seems to wear out the drivers eventually. Notably, Hans Zimmer's The Dark Knight scores. They seem to be particularly heavy on the bass and the drivers will begin distorting on that eventually. I still love them.
Pros: Portable, better sound than any earbuds, so light sometimes I forget I'm wearing them
Cons: Drivers get overdriven and ruined after awhile
Summary: These headphones for the price can not be beat! Have had them for almost two years. I listen to many styles of music and they have great bass to highs. Also, have abused them running and spin classes and they just keep working. Am planning to buy another set because my wife keeps stealing mine.
Summary: The sound is wicked good with remarkable bass for the price. It is a bit unwieldy and I don't like how it sits over my ears. It seems heavy. I tried running and it seems to stay in place while jogging. Overall I am happy.
