ACS was established in 1994 as a company dedicated to hearing conservation and the manufacture of custom-fit, soft silicone hearing protection and In-Ear Monitors.

ACS developed its own range of high-fidelity hearing protection, which is now the music industry’s go-to product worn by thousands of musicians, DJs, music lovers and live events professionals worldwide. ACS was also a founder partner of the UK charity funded Musicians’ Hearing Health Scheme and works closely with other associated industry organisation and education institutions in raising awareness about hearing conservation.

ACS has also grown its international reputation through a range of dealers, manufacturing partners and dedicated ACS facilities and now operate in over 25 countries setting the standard across the world for those who are Serious About Sound.



We have chosen to support the Make Listening Safe Campaign to promote avoidable hearing damage from headphone use because it is another important part of the ongoing mission to make music induced hearing loss a thing of the past.
