Introducing the 64 Audio Solo – a revolutionary leap in portable high-end audio that redefines the meaning of "full-range sound" in a single-driver IEM. Harnessing the power of a single 14.2mm planar magnetic driver, Solo expertly delivers unparalleled sonic detail and clarity across the entire audio spectrum. Drawing from 64 Audio’s legendary tia™ line, this innovative design has been years in the making, blending cutting-edge acoustic engineering with a deep respect for our heritage of technological disruption.

64 Audio Solo Planar In Ear Monitors

Inspired by the iconic Fourté, Trio, and Duo, Solo uses advanced technology to solve the modern challenge of tuning a single driver for maximum performance. At the heart of this innovation is the world’s first use of Helmholtz resonators in an IEM, with two meticulously tuned micro-cavities 3D-printed into the acoustic chamber. These resonators precisely shape the frequency response, delivering refined sound with exceptional depth and clarity. Additionally, our patented apex™ core design relieves pneumatic pressure, providing an expansive sense of space and unparalleled listening comfort for extended sessions.

Solo’s planar magnetic driver stands apart from traditional dynamic drivers, featuring a flat diaphragm suspended between dual magnets. This design allows the entire diaphragm to move uniformly, capturing extraordinary detail and micro-transients without requiring a separate high-frequency driver. The result is a truly high-resolution, full-range sound from a single driver – with the robust low-end presence typically associated with multi-driver systems.

Our patented Linear Impedance Design (LID) ensures consistent performance across all playback devices by compensating for impedance variations, preserving the intended sound signature. The integration of apex™ core further enhances Solo’s design, offering superior fit, comfort, and just the right amount of isolation for immersive listening without occlusion.

With Solo, 64 Audio sets a new standard in micro-acoustic design, achieving the same level of innovation that Fourté did in 2016. Solo’s agile performance captures even the most subtle details, revealing the textures of instruments and the nuances of your favorite recordings. It offers a powerful, deep bass response, seamlessly balanced with the overall sound signature, making it perfect for discerning audiophiles seeking a single-driver IEM that delivers uncompromising quality.

Solo isn’t just a technical marvel – it’s a listening experience unlike any other, merging advanced acoustic technologies into a striking, elegant design. With Solo, we’ve opened a new realm of possibilities, proving that less can indeed be more.

Solo is being paired with our first pure copper cable. The OCC Copper, which is 23 x 25 AWG Wires, is built into eight-braids with a pleasant tactile feel as well as an impressively low 0.26Ω impedance rating. Solo comes standard with two of these cables, one 3.5mm single-ended and one balanced 4.4mm.
