strain. The sheathing on the cable is treated to dismiss harmful UV rays and will not discolour or oxidise like many other inferior cables.

Pro-Fit

The ACS PRO-Fit offers complete versatility as well as incredible sound. One of the smallest, lightest earphones on the market providing the highest levels of sound quality and isolation. The PRO-Fit single balanced armature driver gives remarkable high-fidelity accuracy with smooth bass and sparkling high frequency response. It’s ready to use straight from the box and comes with its own soft carry-case and a selection of interchangeable earbud tips that can be

used to get the best fit for your ear. PLUS! The other unique advantage is that the PRO-Fit earphones can be easily retro fitted to any ACS PRO Series custom earplugs to instantly convert into a pair of custom fit in-ear-monitors.

The PRO-Fit offers incredible sound from a single, lightweight driver that doesn’t compromise on performance. Whether you use the PRO-Fit with universal tips or PRO Series Earplugs* you will get an impressive performance delivering all the detail you need with enough bass to ensure that you get rich and full-bodied sound, even in noisy environments. The PRO-Fit has been specifically designed to offer great isolation in any configuration allowing crystal clear sound

across all frequencies so the PRO-Fit is perfect for listening to or performing a plethora of music genres.

The all new PRO-Fit is a completely redesigned earphone offering unbeatable sound in a lightweight and resilient chassis that’s perfect for both personal listening and live performance. Using a carefully selected balanced armature driver to give the best sound from its more rigid casing the PRO-Fit employs forethought and innovation throughout. Making sure that we use the right cable to deliver your sound is as important as every other aspect in the design of our

monitors so we make sure they are just as well thought out. Starting with the best conductive core we then add Kevlar threads for strength and flexibility so that we can be sure you’ll get the performance you demand. Each cable is sheathed with a special finish that reduces the transmission of friction noise to the earpieces so there’s as little interference as possible. The cable is then clamped at the Y divide with a custom pressed lengthened binder to give it extra

strength where you need it most. Finally, each cable is finished with our custom-moulded right-angled plug offering high levels of resilience as well as quality with a gold-plated 3.5mm connector. *NOTE: ACS PRO Series Custom Earplugs not included.
