The rise in mobile phone-related car accidents has led states such as California and New York to ban the use of mobile phones without the use of headsets while driving. While this may make driving safer, it creates a sharp rise in the demand for hands-free calling devices. Hands-free devices are sold from many different companies, but there are a few basic types from which to choose.
Bluetooth Devices
Bluetooth was created in 1994 by the Ericcson company. Today, it is used in many devices to create a Personal Area Network, or PAN, allowing your Bluetooth-enabled cell phone and headset to communicate for hands-free calling. Bluetooth uses radio frequency to broadcast and receive information in the same way that FM radios operate. The PAN of a Bluetooth signal extends up to 33 feet, allowing you to make and receive cell phone calls without being next to the phone.
Bluetooth Speakerphones
Whereas Bluetooth headsets connect to a device placed in your ear, a Bluetooth speakerphone connects to a device placed in your immediate area, in range of your voice. The Bluetooth speakerphone combines the wireless technology of Bluetooth with the augmented sound output and microphone of a speakerphone. This alleviates the need to insert a device into your ear, which may be uncomfortable and cumbersome to some. Bluetooth speakerphones are particularly useful when including more than one person in a conversation.
Wired Headset
The standard hands-free headset, which is included in the box with many mobile phones, uses a wire that plugs directly into an audio port on your phone. There are two basic types: single and dual ear bud. As the name suggests, the single ear bud headset uses one speaker while the dual uses two. Dual ear bud headsets are optimal for use with your mobile phone's MP3 player as it supports stereo listening. Another popular feature for wired headsets is noise cancellation, which drowns out background noises to allow easier calling.
Speakerphone
Many cell phones have a speaker phone option. Once enabled from your phone call settings, an external speaker on the phone switches on to augment the sound. This allows you to place the cell phone on a nearby surface while talking. Although this can be useful in many situations, it doesn't offer the same levels of privacy that in-ear, hands-free devices give.
