The Com.n.sense hands-free kit enables drivers to answer incoming calls without touching the unit. To pick up calls, waving a hand in front of the system triggers it to activate the call. Using infrared technology and a micro-controller, the system answers the call, which is transmitted through a loud speaker. When the call is terminated, the system automatically begins re-charging the phone's battery.
The system, which plugs into the cigarette lighter socket and is mounted on the dashboard, also mutes the in-car stereo system. It can be used with Nokia, Siemens, Samsung and SonyEricsson handsets.
Ericsson Plug n Go Anywhere
The Ericsson Plug n Go attaches to the vehicle's windscreen using a sucker attachment, enabling drivers to use the hands-free kit at eye level.
Sound is generated from a speaker at the back of the unit which is powered and re-charged using the cigarette lighter socket.
The system is fully mobile and can be transferred between cars or vans and used while drivers are away from their vehicles.
Jabra Freespeak 200
Using bluetooth technology, the Jabra Freespeak can be used up to 30 feet away from the driver's mobile phone. The system claims to offer easy-access volume controls and clear sound quality with minimum distortion.
The earpiece and microphone fit behind either ear, rather than looping around the head. They come fitted with Jabra MiniGel, a small gel tip that channels the sound directly into the ear, providing a better reception and enabling drivers to clearly hear conversations in noisy environments, according to Jabra.
Freespeak comes with a cradle that can be used both in and out of the vehicle.
Jabra Freespeak 250
The Jabra Freespeak 250 offers eight hours' talktime backed by 10 hours' standby time. Using bluetooth technology, the kit fits behind the driver's ear and is made from 'sound absorbing' material to minimise distortion and improve sound quality.
Like the Freespeak 200, the 250 uses the Jabra MiniGel tip to further improve sound quality. Drivers can activate calls by touching a single button on the headset, which also activates modes such as call transfer, last number redial and volume control. It can be used at a range of 10m.
Nokia CK1W wireless/bluetooth
The CK1W is compatible with most mobile phones, not just Nokia as the name suggests. Using bluetooth technology, the system is operated from a single button which activates voice dialling, answers and ends calls and controls the volume. Stereo systems are automatically muted when a call comes through, with the sound being automatically re-instated once the call has ended.
The system can be set for up to eight separate mobile phones and is automatically activated once the vehicle's ignition has been started. The kit comes with a remote control button, hands-free unit, external speaker, microphone, power cable and mounting plate.
Nokia Plug N Go
The Nokia Plug N Go Car kit provides drivers with an instant system requiring no wires or installation.
The system plugs in to the cigarette lighter socket with the driver then placing their handset into the cradle.
The system can be transported between vehicles and all functions including speaker, microphone and volume control are built into the unit which is also charged from the cigarette plug.The system is supplied with an instruction cassette and additional pivoting extension arm.
Plantronics M3000 bluetooth
Compatible with all current bluetooth mobile phones, the M3000 claims to offer crystal-clear audio quality using its 'noise cancelling microphone', backed by easy-to-use volume and mute controls. It also includes a multi-function call control button enabling the driver to access different modes of the system with minimal distraction.
The unit digitally encrypts all calls, which Plantronics claims will improve security, and drivers can make calls up to 10 metres away from the vehicle.
The headset comes with lightweight earloops that allow it to fit to either ear and it can be adjusted to several positions, giving the driver greater comfort.
The M3000 can be used for up to eight hours' talk time, backed by 200 hours of stand-by time.
Plantronics M170 wire
Plantronics has designed the M170 for drivers wanting the option of alternating between using the headset over-the-head or over-the-ear. The convertible headset comes with a choice of three earloops for added comfort and, like the M3000, has a noise-cancelling microphone to improve conversation quality.
The system also comes with an 'acoustic shock protection unit', which protects hearing, and a microphone volume adjust switch hearing aid to minimise distraction. Options on the M170 include an in-line volume and mute control.
Sony-Ericsson HBM-30 bluetooth digital music player
The Sony-Ericsson HB-30 is for drivers wanting more than a standard hands-free kit. The system not only allows drivers to take calls but also acts as an MP3 player that can be used independently of the phone.
It includes headphones which are instantly muted once a call comes through, and re-instated when the call ends. It operates using bluetooth technology.
The system offers ten hours of music playback time and can play both MP3 and ATRAC3 audio files. Drivers are also able to view music track and call information on a digital display. The system comes with a hands-free handset, MagiGate memory duo stick (64mb), case and bluetooth control.
