I recently got the JB Prime to go with my 8900. It is by far the best bt headset I have ever used. There is enough ear pieces and combinations to get the right fit that I don't think that would be an issue with anyone. The fit is perfect to me, which is saying a lot because usually I am extremely picky about earpiece fit, and I can wear it for hours on end without any discomfort. I can shake my head and it never moves. Can't say enough about this unit, and it has the JawBone quality so it works great and sounds great.
