I purchased this bluetooth systems for my Iphone, which it does pair with, with no problems. This is my first bluetooth, so I don't have anything to compare it to, but I find the thing somewhat cumbersome. It is difficult to fit onto my ear (it falls off), especially when I'm wearing glasses, which is most of the time. I've also had some issues with the sound getting crackly for some unknown reason. As far as elimination of background noise goes, it is better than the wired headset provided with the Iphone, but not by that much. I'm not sure why this product has gotten such rave reviews on Amazon.
