The Sound AlertTM headphone visibly signals to students and teachers when the headphone volume is louder than the American Speech-Language-Hearing Association recommended 85dB level.

When the volume that is played through this Califone headphone exceeds 85 decibels, a bright red warning light on the earcup turns on, alerting both the teacher and student about an unsafe sound level requiring adjustment.

Having an appropriate headphone volume level pointed out will help teachers and students learn safe and lifelong listening practices, beginning in the classroom, learning center, or school library.

LED lights: Red will turn on whenever the audio level exceeds 85dB SPL +/- 3dB

Orange indicates the battery is recharging and turns green when fully recharged

Green - the system is on & functioning
