Power suit, power tie, American Express card, neck-mounted Bluetooth headset. That's the ticket right there, folks.
The RoadRunner Bluetooth headset with larynx microphone suppresses noise harder than a Fortune 500 company suppresses its cube-dwellers into a life of mundane paper shuffling and mandatory happy hours.
Your voice is transmitted directly from your voice box so the headset is a great fit for convertibles and motorcycles. Good for nine hours of talk time and apparently has a less than one-percent error rate for voice dialing (however that's been calculated).
It's around $80 US, shipping from the UK.
