A headset with mic combines headphones and a microphone into one wearable device, letting you listen and speak hands-free. They are commonly used for calls, gaming, streaming, or virtual meetings. The mic can be boom (on a stalk) or embedded (in the ear cup). Many models now include noise-cancellation to reduce background noise and improve voice clarity. They come in wired (3.5 mm, USB) or wireless (Bluetooth, 2.4 GHz) versions.
