It may sound like hyperbole, but I believe this is truly the best headset made for a mobile phone. I may not have tried every one out there, but I have owned at least 15 -- from the Nokia earbuds shipped with the phones, to the original Nokia bluetooth to half a dozen other bluetooth headsets (up to, and including, the fragile Jawbone!). This headset, while wired, blows the rest away. I actually use it in my car while driving and can hear everything and am heard perfectly -- and did I mention that my car is a convertible and I have the top down when using it?! Really! When I use this headset with my Blackberry 8830, I am told that it sounds better with the headset than without! Also, the Shure feature of multiple ear adaptors is key -- by sealing the speaker in your ear no outside noise can interfere with your ability to listen to the other party. This is particularly important, again, when driving. I have the same feature on my Shure headphones that i use when working out -- i do not like them for long plane rides but they are perfect for an hour of cardio or a long phone call. Of course, I look a bit like Madonna doing the "Vouge" video . . . ok - only the headset, otherwise i could not look LESS like Madonna . . . but the "fashion statement" with the foam microphone cover is a bit comical. Still, the foam is the main reason the noise level is so low (plus the dual mics) -- it eliminates the wind. This is also a very sturdy piece of equipment. I am still not sure the over the ear piece is helpful or not -- basically it stays on because it is in my ear adn the arm is not that heavy. Also, the arm is VERY flexible so while it gets abused in my briefcase or car, it always bends right back into position. I am ordering two more so i have one in each car, and also one for my girlfriend (who now has headset envy!!).
