The PRO27 (-27dB) is made for the loudest stages and most uncompromising environments. The PRO27 has an neutral attenutation of -23dB in the Low and Mid Frequencies but is characterised by up to a maximum -35dB in the upper frequencies with the seal created by the custom fit shell. In practice, this gives an average attenuation of -27dB, allowing you to safely increase you noise exposure up to 9 times! If you are regularly exposed to very loud environments of 100dB+ then these might be the PROs for you.


ACS custom fit PRO Series earplugs have been designed from scratch to their own specification for optimal performance and comfort. Whether you need them for a work or leisure environment, there is a PRO for you. 


Hearing protection doesn't mean you need to compromise sound quality! The soft silicone earplugs are custom made to fit your ears perfectly, combining a comfortable fit with a perfect seal to prevent sound leakage. ACS PRO sound attenuating filters reduce sound to safe levels naturally rather than just blocking it out like traditional generic earplugs!


Worried you'll get the wrong filter? No problem. Within 60days of purchase, if you feel the filter level isn't right, return the filter we'll exchange it for a different type free of charge.
