The PRO 27 is a breakthrough in high-noise filtering, giving you an almost flat reduction of around 23dB through the low and mid ranges so that you maintain situation awareness and your ability to communicate, but can still be comfortable in very loud environments. In the higher frequencies the PRO 27 gives you a stark jump in protection, offering up to 35dB where you need it most. With an average attenuation of 27dB the PRO 27 can increase your safe exposure time by up to 9 times.

The vented design offers reduced occlusion, making communication sound more natural – resulting in a plug that is more transparent to the wearer. The complete plug (custom made in soft silicone) offers one of the most comfortable hearing protection solutions with the additional benefit of water resistance for increased longevity.
