Sena Earmuff Cradle for 50S, 30K and 20S EVO (SC-A0333)

The Sena Earmuff Cradle (part number SC-A0333) turns the main module of a Sena 50S, 30K, 20S EVO or 20S helmet headset into an over-the-head earmuff headset. It lets you use your Sena communication system without a motorcycle helmet, for example in the pit area, on a work site or on the water.

The cradle combines over-ear hearing protection with built-in speakers and a removable boom microphone. Internal microphones pick up ambient noise so you stay aware of your surroundings in high-traffic areas, and audio uses Sena Advanced Noise Control.
