Buying a hands-free kit for your cell phone is no easy task. There are lots of choices so here
are your options and what you need to know:
Earsets
Earsets are the least expensive and the most frequent handsfree kits. They are perfect for those
who want to use their phone in hands-free mode while walking. Since the microphone is closer
to your mouth than with a speakerphone system, the person you are talking to usually hears you
better. They can also be used in your car but struggling with the wires is sometimes a problem.

Speakerphones
Meant for road warriors, speakerphones usually plug in your car's cigarette lighter. The big
advantage here is you are totally hands free. But since the speakerphone's microphone is usually
far from your mouth, people can complain that they don't hear you well, or that you sound as
if you were in an empty swimming pool. For better sound quality, look for full duplex devices.

Phones with built-in speakerphone
Some phones already have a built-in speakerphone: a good option since you can bring it with you anywhere:
hotel room, conference room, taxi, etc. However, speakerphone use drains your
battery power more quickly. Here are some of them:

Panasonic Allure EB-TX310
Sanyo SCP-4700
Audiovox CDM9100
