Hey all, anyone try out that H3 bluetooth headset?

I was curious as to how good it was...especially compared to the HS850? can anyone tell me which one they prefer and why?

I like how the HS850 opens and auto connects, thats really convenient .. but Im also really intrigued by the new H3 Razr piece, I feel like it should be really good but what does it offer that that HS850 does not?

Also, is there a difference between the black HS850 and the Silver/gray one? just colors are any upgrade?

Thanks a ton!
