I have had small chit chat conversations about headsets a lot over the last 3-4 months. No one I know is using a bluetooth headset – not even friend who have invested in it. And I think I have a conclusion:

1) You always loose them
2) You never have the charger with you
3) A wired headset is seems better

Wired headset bonus for me: When i drop my phone (happens 1-2times a day) – the wire saves it from hitting the ground more hen 90% of the time :)
