I own two of these headsets and have been very pleased with their performance. However, I became a lifelong fan just a couple days ago when I mistakenly jumped into a pool with one of the devices in my pocket. I was certain I'd ruined the device, but I let it dry out for about a day, plugged it into the charger (and was delighted when I saw the red "charging" light go on), and found that it worked PERFECTLY. It even retained its synch with my mobile phone without needing to be re-synched! Amazing ... I'm a fan for life.
