Wireless Headsets for PC/Mac

For those of us that need the freedom to walk, talk, and work handsfree while connected to their computer - the answer is a wireless headset.  While all the headsets below connect to a PC or Mac, some offer dual or triple connectivity meaning they can also connect to your desk phone and/or smartphone via Bluetooth.  Another consideration when deciding on a wireless headset is the amount of range needed.  Bluetooth offers between 33 to 300 feet, while DECT offers twice the range between 250 to 600 feet.
