64 Audio’s Top-of-the-line IEMs
U18t is 64 Audio’s top-of-the-line, reference-class in-ear monitors. You’ll enjoy resonance- and distortion-free listening thanks to U18t’s Tia system, while an Apex Core ensures effortless audio reproduction and minimal wearing fatigue. These universal-fit IEMs boast an industry-first design that pushes the limits of what a reference monitor can be. U18t offers unparalleled detail and unmatched clarity across all frequencies, along with muscular lows and incredible sub-bass extension. Tailor-made for mission-critical applications, these earphones are ideal for engineering, monitoring, mixing, and audiophile listening. They boast an eye-grabbing look as well, with an ergonomic shell machined from a solid piece of aluminum and an elegant copper-patinated faceplate.
Distortion-free sound and long-wearing comfort
U18t delivers a first-class listening experience. Its Tia System minimizes unwanted resonances and distortion, delivering a transparent, lifelike sound. Its open-balanced armature Tia Drivers radiate freely into a single large Tia bore, resulting in zero obstructions to the front of the drivers. We’re impressed by this design here at Sweetwater; it offers a significant step up when compared to lesser designs that constrict the sound of their drivers by cramming them into a tube. What’s more, U18t’s Apex Core employs a patented vent that releases air pressure in a sealed ear canal, all while maintaining isolation. This ensures less obstructed airflow, giving you ultra-clean audio along with long-wearing comfort.
