ACS PRO 27 filters feature exceptional attenuation in dangerously loud high frequency environments. They can be used in extreme industry environments, and are popular with sound engineers, event staff and seriously loud amplified musicians.

A Revolution in Custom Hearing Protection

The PRO27 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 situation 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 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 PRO filter series has been designed with the wearer in mind. 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.

ACS PRO sound attenuating filters reduce sound to safe levels rather than just blocking it out.

Note: ACS PRO 27 filters are only compatible with ACS PRO 27 custom earplugs and are not interchangeable with other filters and ear molds in the PRO range.
