64 Audio is the world's fastest-growing custom in-ear monitor (IEM) company, founded in July 2010 by Vitaliy Belonozhko and his wife Anastasia in Portland, Oregon, originally under the name '1964 Ears' before rebranding to 64 Audio in September 2010. The company was born from Vitaliy's desire to create better and more affordable in-ear monitoring solutions, starting with building a single set of IEMs for his wife Anastasia around 2008. Vitaliy Belonozhko, a Ukrainian immigrant who came to the United States at age 10 in 1992, is a sound engineer with over a decade of experience working with musicians and production companies in the Northwest. Now based in Vancouver, Washington, 64 Audio employs the four Belonozhko brothers (Vitaliy, Roman, Vlad, and Bogdan), all musicians and sound engineers with backgrounds in professional live music production and stage performing. The company has revolutionized the IEM industry through patented technologies including APEX (Air Pressure Exchange) pneumatic vents that release ear canal pressure and reduce listener fatigue, 3D-Fit technology combining digital scanning and 3D-printing for precise custom fits, and TIA technology that delivers sound directly without internal tubes. Since 2010, 64 Audio has handcrafted thousands of custom in-ear monitors for world-class musical talent, with all custom and universal IEMs designed, assembled, and quality-controlled by highly skilled technicians in their U.S. facility, offering award-winning products like the A12t and A18s that serve as the gold standard for performing artists across genres while maintaining a 30-day fit guarantee for customers worldwide.
