At USD651, this 64 Audio ADEL U10 is a solid bargain against the original USD1399 MSRP, landing squarely in the fair-to-good used range of USD600-900 I've seen for lightly worn examples on enthusiast markets. These 10-driver universals with ADEL tech hold value well thanks to their pro-grade build and spacious sound, but condition matters—anything under USD600 screams steal if pristine.
Buyers should verify the ADEL modules are included and functional, as they're key to the signature airiness and fatigue reduction; missing or swapped ones kill the magic. Also check for cable integrity and serial-matched shells, since detachable leads fray and acrylic can micro-crack from drops over years of stage abuse.
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.
