They promote this unit as noise canceling and wind canceling. NOT! In windy conditions, despite the little piece of foam over the mike, no one can hear me. I'm talking 10 mph, not hurricanes. Loud background noise also gets through. This is a disappointment as Plantronics makes great noise canceling headsets for pilots.All of that said, it is light, comfortable, connects to both my phone and computer, and is usable with my voice recognition software. The volume is good, and so is the clarity. It's easy to use and the battery lasts all day. Recharge seems quicker than other headsets I've had. Had they not advertised this as noise canceling I would have given it five stars.If you don't expect it to perform miracles in high noise environments, you will be very happy with this headset.
