Noise-cancelling amplified microphone with Uniden wiring CB radios. A high quality amplified microphone from this famous USA manufacturer, with noise-cancelling, ideal for mobile use.

Unlike many amplified mics, which are too sensitive and pick up every bit of background noise, these are designed especially for mobile use. The noise-cancelling circuitry means that only sound close to the microphone (ie your voice) is amplified and background sounds (eg your engine) are not.
