Because it's not just what we do, it's the way we do it.

All ACS products are made using medical-grade silicone. It's not the easiest material in the world to work with and sometimes this means going that extra mile to get the finished product just right but nobody ever built anything great easily. We believe that using silicone gives you the best fit, the highest level of comfort and, most importantly, the best sound and it's not just us that think so. Our ER-Series of musicians hearing protectors have been independantly tested to conform to European standards for noise exposure and these results show our ER protectors to have the flattest response of any musicians' hearing protector worldwide which is why so many musicians make sure that they ask for the ACS ER to be sure that they're getting the best possible result from the best possible filter.

Because innovation is not just another blade in your razor.

Nobody ever actually asked for a five bladed razor. The belief that bigger is better combined with a relentless focus on what's considered to be a headline feature can sometimes actually result in a complete lack of ingenuity. ACS innovate in all areas of product design to make sure that what we produce is as good as it can be from top to toe. When we improve our monitor range we don't just add another driver and call it ground breaking we look at the build, the wiring, the cross-over components, the cable, the plug, the joints, the finish and even the case we send them in so that every aspect of our product is delivering what we want it to. Without adding a single driver to our range we've improved the sound by adjusting the cross-over builds and wiring, improved the strength by adding Kevlar reinforcement to our cables with improved Y-joints and fortified gold-plated connectors, improved the listening experience by adding a sheath to the cable that prevents friction noise being transferred to the earpiece and improved the fit by modifying our moulding and lacquering techniques. It's this continuous improvement that we believe gives you the best in-ear monitor in the world rather than just adding one more speaker.
