Listen to Radio or Your MP3 Player While Protecting Your Hearing

Input jack accommodates MP3 players, CD players and communication radios. Speakers are limited to a safe 82dB level. Electronics have been separated from the hearing-protection cavities to avoid problems associated with moisture and sweat that can limit the system's lifespan. 2 AA alkaline batteries (included) last about 150 hr. System automatically shuts off after four hours to protect batteries. 25NRR.
