The tapered tips of EARflex 28 are made of an exclusive new product, EARform foam. This hybrid foam formulation reacts to the body temperature, warms, conforms and actually becomes softer with wear time. Just think, a hearing protector that keeps feeling and fitting better as the day goes on.Better Fit With a Twist.Unlike many other semi-aural devices, EARflex 28 tips pivot for easier and better fits. Also, once in the ear, they move with the wearer so they’re less likely to become dislodged and break the seal against noise. Look And See The High-Viz Band. Ideal for airport and road crews, the bright orange band has the high visibility advantage for added safety. It’s flexible so it gently wraps around the head without “clamping around” it. Plus, it’s so lightweight it’s almost undetectable.
