Flagship, 18-driver, custom fit earphone. Designed for the most demanding listeners who are looking for the ultimate in reference sound. 1 tia™ High, 1 High-Mid, 8 Mid, 8 Low. Integrated 4-way passive crossover.

The 64 Audio A18 Tzar™ is the world’s first custom-fit earphone with 18 balanced armature drivers per ear. Designed for the most demanding listeners who are looking for the ultimate in reference sound, it features 8 low drivers, 8 mid drivers, and the incredibly smooth tia™ high and high-mid drivers. Sound from the low and mid drivers combines in the tia single-bore and blends with amazingly-detailed highs from the proprietary open balanced armature tia high driver. The result is an incredibly tight low end, super transparent mids, remarkable high-frequency extension, and an out-of-this-world depth and soundstage. A protective mesh covering at the end of the stem helps to keep out debris while apex™ module technology allows for customizing the sound signature and reduces air pressure inside the ear canal for fatigue-free listening. We pushed the limits with innovation and design to fit such a driver package in a custom earphone and are thrilled to finally drop this bomb on the in-ear monitor industry.

Like all 64 Audio Custom IEMs, the A18 monitors are 3D printed based on your uniquely shaped ear impressions and are fully customizable with a wide range of handcrafted finishes. They are inherently noise isolating and are designed to work with a wide range of personal audio devices including all hard-wired and wireless monitor systems.
