I had been using the older version of the Jawbone Ion. It was a very good Bluetooth headset but I had it for quite a while and it finally quit. In reading reviews, the new version is a very hit and miss proposition,. That doesn't work for me. I tried 3 separate replacements: Pantronics Voyager Legend, Motorola Hint and the Jabra Stealth. The Plantronics was good sound on both ends but uncomfortable in my ear so I returned it. The Hint turned out to be hit or miss. Sometimes, it had better sound on both ends than just using my phone. Other times, the callers couldn't hear me. Strike that one. The Jabra Stealth has turned out to be a stellar unit. It is loud enough for me that I have to turn the volume to about 1/2. Callers tell me it is crystal clear on their end. I tried it out in the wind and was told that, while I'm talking the noise reduction eliminates all other noise. When I'm not talking, they can hear the wind coming through. Another plus is battery life. I have only been using it for a couple of weeks, but I went 3 days with several calls and it on most of the time and it showed a battery life of 85%. Much better than the Hint for sure. I have read 2 complaints about this headset. One, the voice announcing calls and other "system" sounds are not as loud as the caller. That is true. It is sometime hard to hear the caller ID. But, I've never missed a call because I didn't actually hear it. Two, there isn't a volume control on the headset. I actually prefer this. You control the volume using your phone. It is much easier for me doing it that way. I know the complaint is you have to pull your phone out to do that, but I actually set the volume when I originally started using it and have not had to set it again. All in all, this is probably the best Bluetooth headset I have used.
