Noise filtering is indeed pretty good with this headset. Not as impressive as the ads and some reviews pretend, but overall quite effective.However, the quality of the pretty-looking plastic case and the electronics inside is rather poor, certainly not worth anywhere near the 100-odd dollars they want for it. While I am not especially impressed with the build quality, it isn't terrible. Far more important, the headset failed on me after a mere 8 weeks of use. It seemed to be working just fine, I had it paired with my iPhone. But then one day it suddenly started dropping the bluetooth link. I then tested it with two different computers and a Samsung cell phone. It pairs up just fine, but will not stay connected to anything for more than 5 seconds. I do not spend a lot of time on the phone (maybe 60 minutes a day), so this very short lifespan was a surprise. Worst of all, this headset let me down without warning on an important call in my car, right when I needed it most.I have yet to experience how good or bad Aliph's warranty service is. Hopefully they stand behind their product and will replace mine without a fuss, but I'm not optimistic that it will take less than another 8 weeks to find that out. In the meantime, I have to buy a replacement anyway, as I can't go without a headset for very long.If you really need the noise reduction, this is a good headset. But if you want a headset you can depend on, look elsewhere. If it cost $40, I'd give it two or three stars, maybe four if it still worked. But for $100+ of my hard-earned dollars, I expect a way better product than this.
