64 Audio revolutionized the IEM industry in 2016 with its world class reference level U18t, the world’s first 18-driver earphone. Now, with the introduction of U18s, 64 Audio has taken the heritage of the 18 driver platform and further pushed the envelope of innovation in sound and design. U18s combines proprietary drivers, LID technology and a new electronic crossover network to deliver a uniquely exceptional listening experience.


64Audio's crossover circuit replaces traditional acoustic dampers used in traditional IEM design which can introduce unwanted distortion through vibration and air turbulence. Rather than using acoustic dampers to filter unwanted frequencies after the driver produces them the electrical low pass filter lowers distortion by eliminating unwanted frequencies before they reach the driver.


U18s is handcrafted in the USA from aerospace-grade aluminum billet. CNC milled, sand blasted, fly cut, and twice anodized - the result is a striking fractal design that is inspired by nature itself and makes a real statement.


How does it sound?

At DCA, we love the sound of the U18s, if you want to experience it for yourself and how it stacks up against the rest of the 64Audio range including the Volür, Fourté and U18t, please get in touch for a Demo - but here are 64Audio's tasting notes:


"Listening to U18s gives the sense that a filter has been lifted off of your music; it is suddenly more direct and vibrant. Resolution and presentation that reveals details which have previously gone unnoticed. The space between you and the performance is removed; the difference between hearing the best reproduction and experiencing it being played in real-time. The enveloping sound-stage and wide frequency response allows you to really press into the music without fear of harshness or fatigue."
