64 Audio U12t (2025 Revision) Universal In-Ear Monitor (Open Box)
U12t 2025 Revision
New Look. Same Legendary Sound.
- Raised Metal Logos
- New Shell Color & Texture
- Chamfered Faceplate Bezel
- U12t silver color electroformed stainless steel faceplate chip
- Now comes with all current apex modules and two cables terminated in 3.5mm & 4.4mm. U12t is the first UIEM that will come standard with our Pearl Premium Cable
- Along with the cosmetic changes, U12t is now packaged in a newly designed unboxing experience seen launched with Solo
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.
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.
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.
Patented Technology
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.
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.
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.
