These work pretty well. They have good highs and lows. I do wish that the bass was a little deeper though. If you're just listening to music they're great, but if you want to mix songs or hear certain parts of a song more in depth, they may not be the best for that. They do not last long, within two weeks the left ear lost some of the sound. It did not completely go out, but it's not nearly as loud as it should be.
edit: After not even a a month and a half of having these they do not work at all in either ear.
