Overall, I am well pleased with this Voyager 510 bluetooth headset. I previously used a Jabra BT250. While the design was nice on the Jabra(behind the ear, out of sight) I regularly experienced the frustration of dropped calls. I've not had a single call dropped by this Voyager 510 and have been using it for a couple of months now. I'm getting good sound quality, and I think it does work better in windy/noisy conditions. It feels slightly wobbly on my ear and sometimes it seems like I wouldn't be able to hear the call well because it doesn't seem to be seated in the ear very securely, but when a call comes in - it's loud and clear! This model does not go INTO the ear canal, but rather rests against the opening of the ear canal. It's pretty easy to get this one comfortably seated on the ear. Once in place, it's barely noticeable!Overall, a good bluetooth headset!
