Pros: Does a good job of getting rid of the car noise. People don't even know that I am in the car. Really good price for a system with noise canceling and echo reduction. The same unit sells for over double the price at the cell phone store. I find it comfortable to wear.

Cons: Not as good as the high end headsets. Clarity could be better.

Overall Review: My iPhone does not support all the features of the head set... like voice dialing and listening to music. That is a knock against iPhone, not this headset.

Pros: Easy to use. A good set of features. The clip works really well for exercise. Reception on FM radio is OK. Priced well for its feature set.

Cons: Does not work well with Linux. Had problems getting it to mount. Although it was connected, it would not charge the battery. Downloaded the firmware upgrade from Sansa, and that improved things... but still not as good as I would like. But, on Windows it works great.
