A Bluetooth headset is a wireless audio device that connects to smartphones, tablets, or computers using Bluetooth technology. It allows users to make hands-free calls and listen to music or media without tangled wires. Designed for convenience, most models feature built-in microphones and noise-cancellation technology for clear communication. They are lightweight, portable, and often come with adjustable ear hooks or cushions for comfort. Battery-powered, Bluetooth headsets typically offer several hours of talk or playback time. Many support voice assistants like Siri or Google Assistant for easy control. Some models are water- or sweat-resistant, ideal for workouts or outdoor use. They can connect to multiple devices simultaneously for multitasking. Overall, Bluetooth headsets combine comfort, functionality, and mobility for an enhanced audio experience.
