Radio and Electo radio earmuffs have been upgraded to include both AM and FM capability. The earmuffs feature an external switch to make it easy for users to select the desired frequency band, and the Electo model is available in both headband and cap-mounted versions. In addition to an AM/FM radio, the Electo model allows wearers to hear important communications, such as co-workers, alarms and other warning signals, at a safely amplified level, while listening to the radio. Directionally positioned microphones provide more natural hearing. Through advanced response technology, Electo amplifies incoming sounds to 82 dB, then acts as a passive earmuff for sounds above 82 dB.
