I've been using this kind of headset for 3 years now. I'm buying my third one now so I can say I'm pretty pleased by it. The best feature is the AAA battery and the long talk time it gets u. I'm a driver and sometimes I talk for 12 hours in a row so if u talk that much is one of the best solutions for u. As for the durability I can tell u it's about a year if u talk like me. It paired good with my nokia phones. My advice is to try any headset u want to buy before u actually buy it(maybe from a friend that already has it#. The real test is to use while driving because that's when u can find the quality of the sound. One of the things I observed is that the quality of the sound depends not only by the headset but by the phone too. #for example one of my friends got a nokia bh-604 and first he tried it with a sony ericsson phone but the background noise, while driving, was horrible, then he got an iphone and was ok). I think every headset will work fine in a quiet enviroment so test it on the road. So in conclusion the key is to find the headset that pairs without problems with your phone.
