This is even better than the original - 50% smaller, lighter, looks less like star trek hanging off the ear. And the noise reduction is as good or better than the original. I love that it's lighter, so my ear doesn't get tired from the weight. The important thing is, you have to position it correctly- aimed at your mouth and with the mic side in contact with your face in order for noise reduction to work. Seriously, I can wear this in the car with the convertible top down and people don't hear the wind. It's that good.
