Encourage compliance while ensuring worker protection with the new Radio Hi-Visibility earmuffs. Designed with bright green earcups and a reflective headband that glows when exposed to light, these earmuffs contrast against dark settings or extreme weather conditions to promote user safety. For enhanced protection, muffs feature a radio volume limit of 82 dB, Air Flow Control™ Technology for high attenuation across all noise frequencies, and replaceable snap-in ear cushions. Not only are they safe, but also they will motivate employees to remember their hearing protection, thanks to an AUX input that allows for connection to MP3 players and other portable audio devices. Includes 2 AA batteries and 2.5 mm connection cable. Tested to ANSI S3.19-1974.
