Trusted by Professionals.  Built for Performance.

Founded in 2012 in New York City, 1of1 Custom was built to meet the demands of professional musicians, DJs, and performers.  What began as a precision in-ear monitor company has evolved into a global audio brand delivering custom-fit hearing protection and performance monitoring systems trusted by touring professionals and discerning listeners worldwide.

With expansion into the San Francisco Bay Area in 2017 and Nashville in 2020, 1of1 Custom continues to operate at the intersection of music, technology, and hearing health, supporting artists on stage, in studio, and everywhere in between.

Hearing Is Not Replaceable

Every day, millions of people are exposed to harmful sound levels on stage, at concerts, in workplaces, and in everyday environments.

Traditional solutions either block sound completely or distort it.

We believe you shouldn’t have to choose between protecting your hearing and experiencing sound the way it was meant to be heard.

Engineered for Sound. Designed for Life.

1of1 Custom products combine advanced acoustic engineering with precision-molded fit to deliver true isolation, balanced sound, and long-term comfort.  Unlike foam or passive solutions, our designs reduce harmful frequencies while preserving tonal accuracy, clarity, and detail.  Each product is built to perform on stage, in the studio, and in everyday life.

Proven on Stage. Trusted Worldwide.

With tens of thousands of custom fits delivered globally to date, 1of1 Custom has become a trusted partner for artists, engineers, and production teams operating at the highest levels.

From global tours to live events and high-performance environments, our products are relied upon where sound matters most.
