We'll keep your ears on file...

ACS is pleased to announce the introduction of a new state of the art scanning technology that means ALL customers that order custom made hearing protection and in-ear monitoring products from ACS will have their ear shape on file at ACS for up to 4 years. The device will scan the impressions and save as a file on the database so customers can order new products or replacements instantly without the need to have new impressions taken. What's more, this service will not cost customers anything extra on top of the standard product charge, it is just a little something we want to do to make your experience with us even more enjoyable!

Please be aware that the scanning service began on May 1st 2010 so will only apply to customers that ordered thereafter. 


Ricci Riccardi

ACS IEMS particularly the T1 ambient are perfect for reducing the volume of a live show whilst giving me an accurate, crisp, controlled, punchy mix from the monitor board. The silicon makes them more comfortable to wear over a long period of time as well as helping them to stay in my ears and keep the seal which protects my hearing.

Mike Brown talks about his ACS T1's

For me ACS In-Ears have the best quality you can get. With these T1's you won't need anything else!

Where can I buy ACS products?

ACS products are available from a nationwide network of Audiologists as well as directly from us at our offices in Banbury. You'll need to make an appointment to have impressions taken which will then be sent on to us to allow us to manufacture your custom-fit products. To find your nearest Audiologist see the complete list on our Find A Dealer page. Please note that production time is always dependent upon orders received.  The skills and experience involved in making our hand-crafted products are not acquired overnight so employing more staff, whilst increasing our labour force, does not bring an immediate reduction in production time - please bear with us in times of increased demand for our products

Action on Hearing Loss – formerly the Royal National Institute for Deaf People – is the national charity helping people confronting deafness, tinnitus and hearing loss to live the life they choose. It enables people to take control of their lives and remove the barriers in their way, giving them support and care, developing technology and treatments and campaigning for equality. Since the charity’s foundation in 1911, it has grown to be the UK’s leading deafness charity, supporting more than a quarter of a million people each year and running the world’s largest donor-funded hearing research programme.
