I have had my Plantronics 855 for awhile now..
It has taken some serious abuse and keeps working.

Battery life ususally exceeds the Touch Pro that i currently have.
Although it might match the life on the TP2
I know its not waterproof.. But its the only one i know that has good batt life and is compact.
