Bluetooth hands free technology allows users to make and receive phone calls without physically holding their smartphones. It enables wireless communication between a mobile device and a hands-free system, such as a car’s audio system or a standalone Bluetooth headset. By connecting wirelessly via Bluetooth, users can answer calls, place calls, and control other phone functions using voice commands or buttons on the hands-free device. This technology promotes safer driving practices by allowing drivers to keep their hands on the wheel and their eyes on the road while staying connected to calls and other essential mobile functions.
