One way to do it is to wear a Bluetooth headset--you can opt for either a monaural (or mono) headset or stereo headphones . This archetype of in-ear setup can work great, as long as you have a secure and comfortable fit and you're able to tap buttons on the earpiece to handle calls without getting distracted.

An even more intelligent idea, however, is to use a Bluetooth speakerphone designed for your car. Consumer-ready speakerphones typically attach to your sun visor, but you'll also find units that handle your windshield or sit on your dashboard. More-sophisticated Bluetooth speakerphone car kits can also be wired into your car--usually by a mechanic, or factory-installed. For wired setups, the components are integrated with the dashboard, and some kits posture the microphone on your rear-view mirror and a control widget on the steering wheel, for example. Our reviews here cloak the plug-and-play kind.

Once paired with your Bluetooth cell phone, an in-car speakerphone lets you push a button to publish calls and accept or reject calls. In addition, provided that your cell phone supports voice dialing, you can utter communicate commands ("Call Harry Work," for instance). Ideally you won't have to take your eyes off the road; you should be able to access the controls by strike one alone. Some units also provide extra features, such as music streaming via Bluetooth and the ability to transmit sound over FM frequencies. (Theoretically, seeing as you can expel the units from your car, you could prop them up and use them as speakerphones at work or at home, too.)
