If you're like me and find most Bluetooth headsets uncomfortable and/or inconvenient to use, the AXVisor (model TRIBC200) from Tritton Technologies might be just what you're looking for. This is a Bluetooth speakerphone unit that, as its name suggests, clips to the sun visor in your car for hands-free conversations.

I tested out the Tritton AXVisor with my AT&T phone, a Nokia 2085 clamshell. I quickly discovered that, as with any Bluetooth device, the functionality of the Visor is limited mostly by the hands-free function on the phone you have.
