A New World of IEM Potential
Immerse yourself in your audio soar across the entire sonic spectrum with Solo in-ear monitors from 64 Audio. Designed to yield top-shelf audio wherever you go, the Solo's acoustic chamber features Tia technology and two Helmholtz resonators, which improve bass extension and frequency while reducing distortion. The company's patented Linear Impedance Design (LID) ensures that said frequency response isn't affected by outside interference. Finally, Apex Core technology ensures hours of comfort while also providing you with a much greater sense of your audience than many other IEMs, which can make the wearer feel isolated. It all adds up to IEMs that retain high audio resolution, afford a great sense of physical space, and offer comfortable wearability.

High detail from a single driver
Most IEMS typically require a dedicated high-frequency driver to deliver intensely detailed audio, but that isn't the case with Solo. Since their planar magnetic diaphragm isn’t driven by a voice coil attached to a cone, the Solo can consistently provide you with true high-resolution, full-range sound from just a single driver.
Helmholtz resonators
Helmholtz resonators work by resonating at certain frequencies while dampening others. Astutely, 64 Audio has placed two very finely tuned resonators in each of their Solo IEMs, thus giving you enhanced frequency response, improved bass extension, reduced distortion, and an improved sense of your soundstage.

Integrated Apex Core technology
64 Audio's apex core technology works alongside the Helmholtz resonators. This combination provides you with optimal amounts of isolation, which allows you to focus on your in-ear audio without feeling completely isolated from your surroundings. With Solo IEMs, you'll be able to enjoy hours of comfortable listening and wearability.
Put a LID on it
Linear Impedance Design is 64 Audio's patented circuit that restores proper interaction with the source. Interference from devices such as smartphones, bodypacks, DAC/amps, and DAPs can lead to changes in your IEMs' frequency response. LID effectively solves this problem and ensures that your Solos always perform their best.

Thinking outside the tube with Tia
The 64 Audio Tubeless In-ear Audio (Tia) system consists of three primary components: the Tia driver, the TIA single-bore, and the Tia acoustic chambers. Together, they provide the listener with transparent, lifelike sounds. Further, the system is a testament to the company's continuous drive to implement the latest technologies and push audio boundaries.
