3M WorkTunes Hearing Protectors have long been an ideal choice for noisy projects (85 decibels and up). But there was room for improvement. To enhance the durability and usability of the 3M WorkTunes Hearing Protector, it was redesigned from the inside out. Significant design improvements make the new 3M WorkTunes Hearing Protector easier to use. Innovative features like Voice Assist allow users to keep the unit on to protect their hearing, while still being able to control music and talk radio with the touch of a button. The Bass Boost option lets users customize their music experience. And with the ability to program up to 50 stations, users can listen to what they want, when they want.
