The world’s greatest soft silicone in-ear monitor just got even better
The ACS Evolve Live! is the new name for the T1 Live! the sound signature and feature set is exactly the same, using the same proprietary detachable cable system, triple driver set-up and crossover design. The only improvement we have introduced is that we can now offer them in more colours than before. You can pick from any of the exciting new transparent colours that are shown in the colour chart.
Reference quality
The ACS Evolve Live! utilises the same three incredible drivers as the ACS T1 Live! offering the largest bass driver in our range alongside mid-range and treble drivers so clear and rich that you can pick out every nuance of your music. The integrated crossover means our engineers have been able to push this combination even further giving you even more detail whilst retaining all of the body and breadth that you expect resulting in perfect balance and unparalleled depth whatever it is that you’re listening to.

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.
