Born Again
This is the redesign of the top selling ACS T1. We have
kept all of its best assets and then improved on the product. The ACS Evolve retains the reference quality and warm frequency response of the T1, if it isn’t broken why fix it? The ACS Evolve features the new detachable Linum cable and socket system, comes in a range of new & exciting transparent silicones and is the same price as its predecessor.
You are only a few simple steps away from owning a custom-made product...

Please note, if you're placing an order with ACS USA for the first time you will need to supply ear impressions. Once you've placed your order, please call our office and we'll help locate your nearest audiologist. If you're in New York or Los Angeles you can take advantage of our free ear impression service at ACS offices. If you're outside of New York or Los Angeles don't panic, we'll make sure we find you a great audiologist nearby (expect to pay between $30-$70 for ear impressions).

If you've had a custom product from us within the last 4 years, we'll have your ears on file. If you want us to use those impressions, just reply to the confirmation/invoice email after your purchase has been completed and let us know.


The PRO filter series has been designed anew with the wearer in mind. For starters, 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. The filters are also user-swappable so you can chop and change as your environment demands to any other filter in the PRO range, giving you complete control over your protection with just a single set of earmoulds. In addition, the PRO series are water resistant so they can be used outside or in high moisture environments and can withstand perspiration without it damaging the filter membrane.
