Lets face it, most bluetooth headsets aren't worth a darn. its just the cell phone manufacturers trying to make an extra buck selling a piece of plastic with a speaker and mic and charging an arm and a leg because its "bluetooth". Well i have to tell you the Jawbone is the exception to the rule. You all know about the noise reduction on this headset. So i won't go into that more than to say its no lie its as good as advertised. and the incoming sound is great as well. at first i didn't like it. it sounded a little tinny but i found that that was their voice with all the unnecessary frequencies elimated. they are much easier to understand. It kinda sounds like the incoming sound you hear when people talk on aircraft radios.
