Features
Important!
WorkTunes Hearing Protector comes
equipped with decibel limiter. A decibel
limiter limits sounds entering the ear to
82 decibels in order to help protect
hearing from Self-Induced Hearing Loss
(SIHL). This means that music can be
listened to at a safe level and will not
exceed 82 decibels.
