The PRO27 custom moulded ear plugs are a breakthrough in high-noise filtering, giving you an almost flat reduction of around 23dB through the low and mid range frequencies so that you maintain situational awareness and your ability to communicate, but can still be comfortable in very loud environments. In the higher frequencies, the PRO27 gives you a stark jump in hearing protection, offering up to 35dB where you need it most so you can carry on working or enjoying your passion in safety. With an average attenuation of 27dB, the PRO27 can increase your safe exposure time by up to 9 times.

The PRO27 custom earplugs provide high-noise filtering, hearing protection. Protect your hearing while maintaining situational awareness.

The PRO filter series has been designed anew with the wearer in mind. For starters, it’s smaller than many competing filters, meaning that it can fit into smaller ears without any protrusion which is great for both comfort and aesthetics because it will always fit snugly underneath a helmet or other head wear. The filters are also removable so you can clean and maintain your ear moulds and your filters – giving you the maximum life and the best value for money from your plugs. In addition, the PRO series are water resistant so they can be used outside or in high moisture environments and can withstand perspiration without it damaging the filter membrane.

The PRO27 is a breakthrough for Heavy Industries with high-noise filtering, giving you an almost flat reduction through the low and mid-range frequencies so that you maintain situational awareness

PRO27 ear plugs are natural sounding and limit occlusion

Trying to create a natural sounding ear plug is no mean feat as far as your own voice is concerned because, as you may have experienced, when you block off your ear canal your own voice starts to boom inside your head (this is what we call occlusion). This is caused by sound that is carried to your ear canal through the cartilage at the side of your head which usually escapes through the open ear canal so is not heard. When we block off the canal this sound cannot escape and so creates that booming effect. A large amount of occlusion can be eliminated by ensuring that the earplug sits deep enough into the ear canal to extend past the cartilage. This ensures that the sound hits the plug and is deadened rather than entering the canal at all. The PRO filters go one step further by being vented to allow sound to pass both ways, meaning that remaining sound can escape directly through the filter providing one of the most natural sounding earplugs available.

    I have just received my new PRO27 earplugs. They are very comfortable so far and I’m looking forward to using them at work soon. A big Thank You to Fleur for all of her assistance. Nothing was any bother which made my tight schedule a breeze! I would gladly recommend Pacific Ears to anyone needing custom earplugs. Thanks.

    Comfortable airplugs. They made everything very easy from exploring potential other places near my work to get fitted (which weren’t already on the preferred supplier list) through to the final product. Thanks so much
