PACS Pro 31 – For use in extreme industry environments

From: $317.00

The PACS PRO31 Earplugs are a revolution in custom hearing protection, providing an almost flat sound reduction. These earplugs are designed with the wearer in mind, featuring a small size for comfort and aesthetics, and can fit snugly underneath a helmet or other headwear. The filters are removable for cleaning and maintenance, and are water-resistant, making them suitable for outdoor use or in high moisture environments. The PACS PRO31 earplugs tackle the occlusion effect innovatively, ensuring the earplug sits deep enough in the ear canal to extend past the cartilage, and the filters are vented to allow sound to pass in both directions. This results in one of the most natural sounding earplugs available. The earplugs are custom-made using soft medical-grade silicone for the best isolation and fit. They have been tested and certified to AS/NZS-1270 standards as a Class 5 Hearing Protector, as well as the EN352-2: The European Standard for ear plug hearing protectors.



The PACS PRO31 is a breakthrough in high-noise filtering, giving you an almost flat sound reduction.


The PACS 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 PACS 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.


Trying to create a natural sounding earplug 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 PACS 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.

Tailor-Made Hearing Protection

The PACS PRO31 ear plug is custom-made using soft medical-grade silicone so you get the very best in isolation and fit, allowing you to wear them for hours at a time without fatigue or discomfort. Each earpiece is manufactured to the highest standards, ensuring you get a comfortable, discreet and effective hearing protector that can be fitted quickly, easily and securely every time.

PACS PRO31 ear plugs and filters have been tested and certified to AS/NZS-1270 standards as a Class 5 Hearing Protector, as well as the EN352-2: The European Standard for ear plug hearing protectors.

What is the highest DB rating for ear plugs?

Our solid earplugs attenuate (reduce) the most. A pair of sleep plugs reduces about 30-33 dB. For industrial noise the Pro31 and Pro27 are the highest attenuating filters: both class 5.

Please note that it is not possible to block out all sound, not even with a custom hearing protection product as sound also travels through the bone structure of your head for example.

Pro10 – For Acoustic musicians and small ensembles. For light protection in everyday environments

What is the hand grip / cord / standard option for the Pro earplugs?

There are different options for our Pro hearing protectors. Standard / Hand grip / Cord / Hand grip with a cord thread through the hand grip. Each option (except for the standard) is an additional 11 dollars (handgrip with cord: 22 dollars surcharge).

1.If you choose the Standard option, the earplugs are most discrete. They have a very flat profile. The earplugs can be removed by pushing on the skull side of the ear in an upwards movement. The seal will break and the earplugs can be taken out easily.


2. The Pro with hand grip, has a silicone hand grip on the top of the earplug. This helps with insertion and removal. Depending on your ear shape the handgrip might stick out a bit. (size 8 mm)

3. The Pro with cord and shirt clip. The black lanyard is plugged directly in the earplug. For safety purposes and convenience, the cord is removable and should not be used to pull the earplugs out of the ears. If you are after a removal option only, please select the handgrip.

4. The Pro with hand grip and cord with shirt clip. This option has the silicone handgrip with a hole where the cord runs through. The cord is removable.

Please note: All these options need to be chosen at the time of ordering, as none can be added afterwards. You can order the options in the shop when you order your Pro earplugs.
