ER-20™ Universal Protectors

Conventional foam and wax plugs generally produce 10 - 20 dB of extra high end reduction than in mid and low frequencies. This bias distorts the sound and disrupts the fidelity making voices and music sound unclear and unnatural.

The ACS ER20™ is a cost effective, ready to use, one-size-fits-all earplug that closely replicates the ear's natural frequency response. The earplugs reduce sound levels by 16dB while minimizing high frequency roll-off providing high fidelity hearing protection for musicians and users in clubs and concert arenas.

The goal of the ER20™ design was the same as for Musicians Earplugs: to reduce noise but preserve sound quality; in effect, to turn down the noise but not muffle voices, environmental sounds or music

ACS ER20™ conform to EN323-2 and are provided with a carry case, neck cord and instructions.

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.

How to Buy

View the coverage map >>

Or redeem a CUSTOM VOUCHER at your nearest impression taker using our postcode store locator >> 

Please note - ACS products require good deep impressions in order to create a seal in the ear so it is important there is no wax block in the canal that will stop the audiologist from taking an impression. If you think you may have a wax build up, please visit your local GP for a consultation before booking an appointment with a dealer. You may be charged a fee if the audiologist is unable to take an impression.

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
