Safety、Comfort、Connectivity
These Bluetooth-enabled earplugs enhance hearing protection, situational awareness, and communication in noisy environments. They offer volume control, mode switching, and phone calling/answering through a connected app (hearSafe), and can be charged via a USB-equipped case that also serves as a storage solution. Their compact, lightweight design ensures comfort and compatibility with most head-mounted personal safety gear.
The Importance of Hearing Protection
Human ears are designed to pick up low levels of natural sounds. In an uninjured ear, the hair cells with their fine stereocilia can receive acoustic signal normally. All of our exciting machines and inventions have created a whole range of unnatural sounds that the ear isn’t designed to handle. When the stereo-cilia are repeatedly exposed to excessive doses of noise over 85dB, the noise can signaficiantly damage the ear-stereocilia. Damaged ears cannot be repaired,resulting in permanent hearing loss.

"The correct use of hearing protector is not just a guideline. It is a fundamental aspect of workplace safety and health."
"Wearing hearing protectors can definitely lower your risk of developing noise-induced hearing loss (NIHL)."
"Prolonged exposure to noisy environments can cause permanent damage to our auditory system."
“Hearing loss very often is such a gradual phenomenon that the person is in denial."
