Is Bluetooth gendered?

I’ve been in a corporate environment for almost 9 months now (eek!), and it seems to me that a large majority of Bluetooth users are men.  Though I work at a firm with more men than women, my client is a retail firm, so I think I have a gender-balanced sample representing a wide range of demographics.  Has anyone else felt that men seem to prefer Bluetooth more than women?  Any reasons why?

Anecdote.  I received a cheap Bluetooth headset during the holidays, and I love it.  My car is a stickshift, so I can drive safely.  (Talking while driving is more dangerous than just driving regardless of how many hands are being used.)  But I really love being able to do mindless chores – folding laundry, cooking, grocery shopping – while maintaining full use of my hands.  My mom, however, has had 2 headsets and never liked either of them.
