After using it half the day I must say I think it's safe to say the BH-800 will be replacing my JX-10.
The fit is MUCH better. It's louder, since it goes more into the ear. No pairing mode! Just turn it on and pair.
My only complaint it that the power button is small and hard to press.
I think I'll have to find a silver one though. Not too sure I'm liking the brown.
Thanks for the tip John.
