64 Audio - U18T Wired IEM

With 18 balanced armature drivers per ear, the U18t is our most advanced reference in-ear monitor. It is the first reference monitor to be able to reach such high levels of detail, extension, and clarity across all frequencies, and with a powerful low-end and extended sub-bass, just like its custom counterpart, the A18t. Audiophiles, engineering professionals, monitoring and mixing teams, and audiophiles prefer the A18t. All ergonomic shells are machined from solid aluminum and finished with copper-patinated inlays on their faceplates.

Exclusive technologies that challenge traditional in-ear monitor designs to give you the absolute best listening experience.

Tia is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. U18t features two major elements of the tia system: the tia driver and the tia single-bore design.

Air Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations for U18t: mX, m15 and m20.
