Handsfree is a feature that allows you to control your device without having to hold it in your hand. A typical example is a handsfree kit for mobile phones, which allows you to receive calls and talk without having to hold the phone in your hand. This is very useful in situations where hands-free operation is necessary, such as when driving a car. The handsfree device can be wireless (usually via Bluetooth), or it can have a cord that connects to the phone. Many modern vehicles also have built-in hands-free systems that can automatically connect to mobile phones when they are within range.
