Pro27 earplugs: Custom Hearing for High-noise Environments

Pro 27 – Designed for high-noise industrial environments and motor-sports
ACS Pro27 Custom Earplugs

The PRO27 earplug is 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 is small, Comfortable and always Fit Snugly

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 headwear. The filters are also removable so you can clean and maintain your earmoulds 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.

A Natural Sounding Earplug without the Occlusion

A Natural Sounding Earplug without the OcclusionTrying 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 ACS 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.

Pro27 Earplugs are Custom made Hearing Protection

The PRO27 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 custom 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.

    Wonderful product and great service. My custom silicone earplugs and far and away superior else that I have used – convenient, comfortable and effective. Good for any time I need to study, relax or focus in comfort.

    I bought a pair for these for adventure motorcycle riding to cut down wind noise, these are excellent and remove most wind noise. They allow all day riding without fatigue from wind noise or discomfort you get with non custom ear plugs. So happy now ordering custom ones for sleeping.

    Got these specifically to combat wind noise on the motorbike – they work great, are comfy and drown out way more wind noise than I expected.

    These are very good with noise isolation around loud machinery and does the job right.
    They are extremely comfortable and sometimes forget that they are in my ears still.

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 10 dollars (handgrip with cord: 20 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 choose 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.
