What is a free device?

A device without a hand is a device used with mobile phones that allows the user to speak by phone without holding it. Thanks to the help of this device, the user can let the phone sit in one area while talking to a microphone connected to its lapel. Alternatively, it may include a headband that places a microphone in front of the user's mouth. In order to listen to the person at the other end, the user of the ear speaker has placed in one ear.

This type of device has many advantages. For multiple tasks, the device allows you to move easily and complete other tasks when talking over the phone. This can help at home work or filling office duties. It also makes it easier to make notes or write on a computer when talking over the phone. However, there is a flush debate about whether it really does safer management. Supporters say it allows the driver to keep both hands on the steering wheel. The driver is therefore in position to drive more carefully and better control the vehicle.

Opponents of the device without hands claim that while the device releases the driver's hands, the phone is still distracted because the driver cannot fully concentrate on the task of driving. Opponents also claim that the equipment can give drivers a sense of false safety and can only release their hands to complete other tasks that are not associated with control, such as radio adjustment, change of air conditioning, drinking and eating.
