These things are awsome. When placed in the ears correctly, the sound is great.

I even use them while riding on my motorcycle (one ear only), which gets very loud, and i can hear my music just fine. Its great.

The mic is really good but super sensitive. It says it drowns out ambiant sound but it really does not, it picks everything up very loud. But it is far better than the provided iphone headset.

They are also very comfortable. Probably the most comfy in-ear headset i’ve ever owned. I leave them in for hours listening to music and it doesnt hurt my ears at all.

All in all, for $99 its a great buy.
