The Aliph Jawbone Bluetooth Headset is adequate. The noise reduction feature does not work everytime. Sometimes it is hard to hear the party on the other end of a conversation, and the earpiece has broken twice. The last time it broke off within the hole that holds the lower metal post in place. I could not get it out. Often I was forced to push the Aliph Jawbone against my ear to better hear the party on the other end of the conversation who was barely audible as I operated my vehicle. Having to hold the device against my ear defeats the purpose of "hands free" driving. I cannot tell if the noise reduction feature is activated. I would have to ask the party I am speaking to if they could hear background noise. It seems as if half of the time they would say they could hear the background noise. I wish they would add a feature that would signify to me, the user, that the noise reduction feature has been activated and is working. Additionally the earpiece should be made of a pliable material that was flexible and would be able to fit the contour of one's ear without breaking. Generally speaking I am pleased with the Aliph Jawbone. I like the feature where one activates and deactivates a call by simply pressing the bar.
