Description
The 64 Audio U6t is a six-driver universal in-ear monitor that brings the brand's flagship technology into an ergonomic aluminum shell. Each side houses six balanced armature drivers — including an open tia high driver — with an integrated 4-way passive crossover covering 10Hz–20kHz.
Three patented 64 Audio technologies define the design. Tubeless In-ear Audio (tia) pairs an open balanced armature driver with a single-bore design to reduce resonance and distortion. Apex (Air Pressure Exchange) is a vent that releases trapped air pressure in the sealed ear canal; with the included m20, m15, and mX modules you can select -20dB, -15dB, or -10dB isolation. Linear Impedance Design (LID) corrects the varying output impedance of different source devices for a consistent sound signature across smartphones, body packs, DAC/amps, and DAPs.
The dark grey matte shell with a black faceplate keeps the look understated, while the included Apex modules, three types of ear tips, a leather case, and a silver-plated OCC copper 3.5mm cable make tuning and fit easy to adjust. This is a demo unit; its exact cosmetic and operating condition, included accessories, packaging, and warranty coverage must be confirmed by the dealer before publication.
