I picked up a
Jabra Clear when I was at the Apple store over the weekend.... It's pretty nice. It has an ear hook, so it won't fall off. The hook is kinda cheaply made, and pretty stiff, so I hope it lasts a while. It doesn't go into the ear canal, so it is comfortable to wear.
I wish it were louder. It's not bad while just walking down the street, but if I'm walking next to a city bus or a large truck, it is difficult to hear.
The exterior of the unit is like a large button, and if you tap it, it will tell you if it is connected or not. All well and nice, except when I put my hat on (it's getting cold out there) it taps it. *connected!*
I've been using it for the past two days, while walking to the gym, and while running on the treadmill. So far, so good.
