Award-Winning
64 AUDIO U12T
U12t 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.

SOUND
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 aluminum and finished with an elegant brushed aluminum faceplate.
Something special about the U12t is the timbre – it is extremely clean, more so than any other BA setup I’ve heard. Imaging and layering are also stellar as one might expect.
- Precogvision (The HEADPHONE Show)
Amazing bass (for a BA), top-tier resolution and detail-oriented signature.
- Crinacle (In-Ear Fidelity)


Tubeless In-Ear Audio (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. U12t features two major elements of the tia system: the tia driver and the tia single-bore design.

Air Pressure Exchange (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 U12t: mX, m15 and m20.
Linear Impedance Design (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.



Pearl Premium Cable
U12t is the first UIEM that will come standard with our Pearl Premium Cable including both 3.5mm single-ended and one balanced 4.4mm.
