64 Audio U18t

Packed with an unbelievable 18 balanced armature driver per ear, the U18t is our top-of-the-line reference in-ear monitor. This industry-first design pushes the limits of what a reference monitor can be with incredible detail, extension, and unmatched clarity across all frequencies with a powerful low-end and extended sub-bass - just like its custom counterpart, the A18t. The A18t is preferred by critical listeners in engineering, monitoring and mixing, and audiophiles.

Each ergonomic shell is machined out of a solid piece of aluminum and finished with an elegant copper-patinated inlay on the faceplates.

Tia Technology - A tubeless design that reduces resonance for a transparent and lifelike sound signature.

Tia Trió features all three elements of our complete tia system: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers.

Tia Driver
An open balanced armature speaker design for realistic resolution and transparency. By opening a balanced armature, the diaphragm becomes fully unobstructed, reducing resonance in the IEM and allowing sound to travel more naturally to the ear.

Tia Single Bore
A huge advancement in eliminating unwanted tube resonance. The large bore itself serves as a sound-shaping chamber and aids the tia high driver in delivering a linear and coherent frequency response. The short sound path provides remarkable high-frequency extension and smoothness. The large single bore also allows for easier maintenance.

Tia Acoustic Chambers
This specific structural design optimizes driver performance with precise placement of each internal component. The exact placement of each driver delivers what many describe as a three-dimensional, holographic soundstage.

apex Technology - Only from 64 Audio, apex alleviates listener fatigue by releasing air pressure sealed in the ear canal. This venting enables musicians and music enthusiasts to listen more comfortably for longer.

Apex, or Air Pressure Exchange, is a pneumatically interactive vent that releases air pressure from a sealed ear canal. Apex comes in two variations, m15 (-15dB) and m20 (-20dB).

Alleviate Listener Fatigue
When you seal a miniature speaker in an ear canal, the air inside becomes trapped. Apex relieves this air pressure, allowing the eardrum to move naturally, so you can comfortably listen longer.

Extend The Soundstage
Freely moving air extends the soundstage and provides a more natural listening experience. It also preserves bass frequencies and helps the listener distinguish individual instruments.

Hear Your Audience
Custom in-ear monitors provide amazing isolation and help you hear your mix more clearly and at lower volumes than a wedge monitor or earbuds. Apex lowers decibel levels while preserving the clarity of the sounds around you, so artists on stage can connect with their audience while protecting their hearing.
