The bottom line when buying a bluetooth headset:  it's about personal preference and fit.  This heatset fits me great, better than any of the other dozen I've tried on.  BUT-- I am a 5'2" 23-year-old female with quite small ears.  My 6'5" fiance isn't as impressed as I am because the speaker doesn't fit over his ear-- because his ears are BIGGER than mine.  The Motorola H850 would probably fit him better.
