I have had this headset for about 3 months now. The noise reduction is remarkable. I can be in a airport and no one even knows I am out of my office.Wind is a problem with this headset as with any other headset. The noise reduction does not reduce wind noise. If it's a windy day you are out of luck but I don't know of any headset that works that way.Sound - The sound is a little tinny but you get used to it pretty quickly.Comfort - I have owned at least a dozen Bluetooth headsets and this is by far the most comfortable. There are different clips and ear pieces that come with the headset. I have worn it for over 8 hours straight and don't even know it's there.Charging - Propriety USB charger that plugs into the back of the phone. They also supply a plug for an outlet so you can charge it without your computer. I bought 2 chargers one for home and one for my laptop bag.Battery - Very good battery life. I cannot remember exact times but I use it often every day and have not run out of charge yet.Storage - This is the one thing that is a pain. It does not come in a case and putting it in your pocket is a real pain. I know this is trivial but I wish there was a case for it when I am not wearing it.Overall I really like this headset and can honestly say this is the best one I have owned.
