About this collection
64 Audio was founded by Vitaliy Belonozhko, a sound engineer who spent years mixing for musicians and production companies before deciding in-ear monitors could do more than the traditional stage wedges everyone was using. The company launched under the name 1964 Ears before rebranding to 64 Audio, and is based in Vancouver, Washington, where it now employs a staff of engineers building both custom and universal-fit in-ear monitors for the professional and audiophile markets alike.
64 Audio's reputation is built on genuine driver-level engineering rather than incremental tuning tweaks. Its tia technology (tubeless in-ear audio) does away with the small acoustic tubes found in most balanced-armature IEMs, letting the driver's diaphragm radiate directly into the ear rather than through a narrow channel, which produces a smoother, more extended top end with fewer of the resonant peaks that make long listening sessions fatiguing. Alongside tia, the company's patented apex module addresses a problem most IEM makers don't even acknowledge: pneumatic pressure buildup in a sealed ear canal. Apex vents that pressure through a secondary interactive chamber, widening the soundstage and reducing listener fatigue without sacrificing isolation or bass.
That combination of technologies runs through 64 Audio's full lineup, from the tia Trió and Fourté up through flagship models like the U18s, U12t, Nio, and Volür, in both universal and custom-molded form. It's also why 64 Audio has become a fixture on tour with artists across genres, from Beyoncé and John Mayer to Bon Jovi and Alanis Morissette, where reliable, fatigue-free monitoring night after night matters as much as outright detail. The same engineering that keeps a singer comfortable through a two-hour set is exactly what makes these monitors compelling for critical listening at home.
