A headset is a device that combines headphones and a microphone, allowing users to listen to audio and communicate simultaneously. They are commonly used for activities like gaming, video conferencing, and listening to music. Headsets can be wired or wireless, with wireless models often using Bluetooth technology for connectivity. Many headsets are designed for specific purposes, such as gaming headsets that feature surround sound and noise-canceling microphones. Other types include Bluetooth headsets for hands-free phone calls and studio headsets for professional audio work. Overall, headsets enhance the audio experience and facilitate clear communication.
