64 Audio TWELVE Ti IEM – Titanium Limited Edition Flagship

The 64 Audio TWELVE Ti IEM is a limited-edition flagship designed to celebrate nearly a decade of global acclaim for the legendary U12t. Built with aerospace-grade Ti-6Al-4V (Tc4) titanium, this special edition elevates both durability and acoustic precision—delivering a listening experience that defines modern audiophile performance.
Engineered with a 12-driver configuration, the TWELVE Ti delivers a holographic, full-range sound signature. From sub-bass depth to airy treble extension, every frequency is rendered with exceptional clarity, layering, and realism.
At its core, tia® (Tubeless In-Ear Audio) technology eliminates traditional sound tubes, reducing resonance and distortion. The result is a transparent, lifelike presentation with improved treble extension and micro-detail retrieval.
The patented apex® (Air Pressure Exchange) system relieves ear canal pressure, reducing fatigue during long listening sessions while expanding soundstage depth and spatial realism. With interchangeable apex modules (m20, m15, m12, mX), users can fine-tune isolation and airflow to match their preferences.
To ensure consistent performance across all devices, LID® (Linear Impedance Design) maintains a stable frequency response—whether you're using a smartphone, DAC/amp, or high-end DAP.
Completing the package is a premium silver-plated UP-OCC copper cable, engineered for ultra-low impedance (0.29Ω) and superior signal integrity. With both 3.5mm and 4.4mm balanced terminations, TWELVE Ti offers versatility for every audiophile setup.
Crafted for collectors and enthusiasts alike, the TWELVE Ti stands as a timeless fusion of titanium engineering and reference-grade sound.
