64 Audio is commemorating nearly a decade of success with its iconic U12t by introducing the TWELVE Ti, a limited-edition in-ear monitor that elevates the original design with a full titanium build. Launching March 31 through select global retailers, the TWELVE Ti combines the renowned sound signature of the U12t with premium materials and upgraded aesthetics, positioning itself as a collector-worthy flagship IEM.
Built using Ti-6Al-4V (Grade 5) titanium, the TWELVE Ti features titanium shells, faceplates, and even exclusive apex modules. This material is known for its exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility—qualities typically reserved for aerospace and medical applications, now applied to high-end audio.

This comprehensive accessory set ensures flexibility across multiple listening setups, whether you’re using a portable DAC/amp or a professional monitoring rig.
Titanium Design Meets Audiophile Engineering

- 1 high-mid driver
- 6 mid drivers
- 4 low drivers
Apex, tia, and LID: 64 Audio’s Core Technologies
The TWELVE Ti incorporates 64 Audio’s proprietary technologies that have defined the U12t’s reputation:
Apex (Air Pressure Exchange)
Apex modules relieve air pressure inside the ear canal while maintaining isolation levels between -10dB and -20dB. This reduces listener fatigue and enhances spatial realism. The included m20, m15, m12, and mX modules allow users to fine-tune isolation and bass response.
tia (Tubeless In-Ear Audio)
The tia system minimizes resonance and distortion through an open balanced armature design and single-bore architecture. This results in a more transparent and natural sound signature, particularly in the high frequencies.
LID (Linear Impedance Design)
LID ensures consistent sound performance across different playback devices by correcting impedance inconsistencies. Whether you’re using a smartphone, DAP, or desktop DAC, the TWELVE Ti maintains its intended tuning.
Premium Cable System with Low Impedance Design
Included with the TWELVE Ti are two high-quality shielded cables—3.5mm single-ended and 4.4mm balanced—built from silver-plated UP-OCC copper in a 4-core Litz configuration.
With 99 strands per core and a total impedance of just 0.29 ohms, these cables are engineered for maximum signal integrity, low noise, and efficient power transfer. The titanium-inspired aesthetic also complements the IEM’s design for a cohesive, high-end look.
The 64 Audio TWELVE Ti is available starting March 31st through authorized global resellers. As a limited-edition release, it serves not only as a technical evolution of the U12t but also as a statement piece for collectors and enthusiasts seeking a premium titanium IEM experience.
