Musician’s Monitors

To perform your best, you need to hear your best. Stage performers are routinely exposed to hearing damage both from amplifiers and the stage monitors that must be turned up to potentially harmful levels just so that they can be heard above the music. Our inside-the-ear musician’s monitors replace the traditional wedge monitors with precise, isolated sound delivered directly to you, so that you can stay in tune and perform your best.

Custom-Fit Monitors

Our custom-molded in-ear monitors are fitted into medical-grade silicone earmolds that are comfortable for extended periods of wear and form a superior acoustic seal to give you just the sound you need. Precision drivers, integrated crossovers, and discreet cable connections make these professional-quality audio monitors second to none in terms of sonic quality, all in a package that is unobtrusive and will never stand between you and a great performance.


ACS Live! represents more than two years of research and development into creating the most feature-rich custom in-ear monitor available. Built around the unmatched ACS custom-fitting system, Live! monitors incorporate multiple drivers, precision-engineered crossovers, a replaceable cable system, and built-in subminiature flat-response microphones. This allows you to receive ambient sounds through your monitors and to easily control the mix from your wireless belt pack. Hear as much or as little stage sound as you need to keep up with your bandmates, while experiencing the most accurate, comfortable, and discreet stage monitoring available.

Available with three drivers (T1) or two drivers (T2).


ACS in-ear monitors are built around a speaker system so clear and rich, you can pick out every nuance of your music. Reference-quality drivers, precision-engineered crossovers, and a durable, reinforced cabling system combine to form the finest in-ear monitoring option available today—in a package that is both comfortable, lightweight, and dependable.

Manufactured from soft medical-grade silicone, our IEM monitors are comfortable to wear for extended periods of time and form a perfect acoustic seal to make sure that you’re receiving precise, accurate monitoring of your sound system. Close fitting and available in custom colors and finishes, ACS monitors are the perfect, personally fit connection between you, your music, and your performance.

Available with three drivers (T1), two drivers (T2), or a single, compact driver (T3), the ACS IEM is the new standard for quality discreet musician’s monitors.

Universal Fit Monitor

ACS Single Driver T15

The T15 offers the same great electronics available in our other ACS monitors in a more affordable, nonmolded universal fit. These monitors offer a snug, isolating fit and incredible sound from a single, lightweight driver. Ideal for both personal listening and live performance, the T15 incorporates shielded electronics and Kevlar-reinforced connections to ensure durability.

Additionally, if you are user of our PRO or ER series custom-fit earplugs, these monitors can replace the sound-blocking filters in your earplugs, allowing you to upgrade your T15 monitors to a custom fit!
