Elvex QuieTunes 660 AM/FM Radio Earmuffs

Uses 2 AA alkaline batteries (included) that provide 150 hours of use. These earmuffs combine an AM/FM radio with hearing protection and are also iPod compatible. The radio electronics are separated from hearing protection cavities to avoid problems associated with moisture and sweat that can affect the lifespan of the electronics. The earmuffs feature a four-hour automatic shut-off, and the sound generated by the speakers is limited to a safe level by a gain limiter.
