Bluetooth headset: Plantronics Voyager 510

If you're looking for hands-free cell-phone talk without wires, a Bluetooth headset is the way to go. The Voyager 510-USB Bluetooth headset system ($115 - $170) features the same excellent sound quality as its in-office counterpart, the Plantronics CS70, but is meant to be used with either a mobile phone or a PC soft phone.

The USB Bluetooth adapter allows you to switch between mobile phones and softphones by pressing a button, and you can roam up to 30 feet from your Bluetooth device.

Note: Those who use Skype VoIP might consider Plantronics' Audio 910, which adds Skype support to the 510. When a call comes in via Skype, the USB dongle will trigger a ring to your headset and allow pick up and hang up via the headset unit. It's convenient and works seamlessly.
