The U12t is a benchmark flagship IEM, and US$1,699 is a fair-to-good used price rather than a steal. Against a current new price of US$1,999 and a 64 Audio B-stock price of US$1,559.20, this listing sits a bit above factory B-stock but still clearly below retail, so it lands in sensible territory for a clean used pair.
What makes it worth chasing is the U12t’s reputation as an exceptionally polished all-rounder: highly resolving, smooth, and low-fatigue, with a tuning that works across a wide range of genres and doesn’t rely on flash to impress. If the set is complete with tip selection, cable, case, and has been well cared for, the value is in buying one of the safest “endgame” IEM bets; at this price, I’d mostly be checking condition, channel balance, and whether all original accessories are present.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
64 Audio traces its roots to 2010, when sound engineer Vitaliy Belonozhko founded 1964 Ears in his spare bedroom in Portland, Oregon. Frustrated with the limitations of existing in-ear monitors compared to traditional floor wedges, Belonozhko—a veteran of over a decade working with Northwest musicians and production companies—began crafting custom solutions. His initial project involved disassembling his own IEMs to build a pair for his wife, sparking a family-driven venture fueled by his passion for music. Rebranded as 64 Audio, the company marked its 15th anniversary in 2025, evolving from humble origins into a global force now based in Vancouver, Washington.
The brand specializes exclusively in premium in-ear monitors (IEMs), eschewing amplifiers, speakers, or other hi-fi categories. Renowned for proprietary innovations like tia™ technology, which enhances sound clarity and reduces distortion, 64 Audio delivers custom and universal-fit models tailored for stage monitoring and critical listening. These IEMs prioritize comfort, reliability, and sonic precision, with multi-driver configurations that capture every nuance of live and recorded music.
Positioned firmly in the high-end niche, 64 Audio commands respect among GRAMMY-winning artists, front-of-house engineers, studio producers, and discerning audiophiles worldwide, with products sold in 92 countries. Its reputation rests on relentless innovation, technical excellence, and a mission to deepen musical connection—"Hear. Feel. Create."—making it the go-to for professionals and enthusiasts demanding uncompromising performance.
