The almost decade-long global success of U12t, reinforced in 2025 by its cosmetic update, is being commemorated with a special edition.
TWELVE Ti is exactly what the name suggests: U12t elevated through the use of an equally renowned element, titanium, for the shells, faceplates, and exclusive m20 apex modules. The strength, resilience, and bio-harmony of titanium, combined with the legendary sound of U12t, create the ultimate icon of timeless style and performance.


TWELVE Ti does it all, delivering immersive sound and impeccable spatial imaging. Its articulate highs extend beautifully with a warm and engaging low-end response - just like its custom counterpart, the A12t.
Offering reference-level detail, this IEM has become one of the most highly regarded and sought after audiophile UIEMs. Each ergonomic shell is machined out of a solid piece of titanium in a matte natural colour finish.

Specially crafted for TWELVE Ti, this four-core cross-braided cable completes the look for a head-to-toe titanium aesthetic. Made from silver-plated, single-crystal copper (UP-OCC), it offers outstanding noise shielding and transparent signal transmission, with a low impedance of just 0.29Ω.

tia
Tubeless In-Ear Audio (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. TWELVE Ti features two major elements of the tia system: the tia driver and the tia single-bore design.
Apex
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 TWELVE Ti: mX, m12, m15, and m20.
LID
Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 12 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.
