Not bad. I use this one. It's the Motorola HS820. It is lightweight and works very well. It's not perfect but it's a good size, feels good, and the sound is excellent. The mic does pic up wind though. The battery life is very good too. It can be a little delicate when dropped but I figure for $50 I can replace it on the cheap. The best part is that it's only $50.

I also have the Jabra one that looks like a horn and while it is good, it's too big. I like the HS820 because you can slip it in your shirt pocket when you're not using it and it doesn't take up too much room.
