Finnish Bluetooth peripheral company Iqua has an extremely nice Bluetooth headset, the Smartbadge. If you spend way too much time at tradeshows, it is good to have a decent badge holder (God, do I HATE commercial lanyards!). Iqua provides one that doubles as a headset. Battery goes on forever.
Found a viral movie featuring the Smartbadge. It is –of course- politically incorrect. Jhttps://www.youtube.com/watch?v=Wqbet2_xsC4
