64 Audio’s most popular CIEM now available in a universal form. U6t draws from the sonic palette of U12t; boasting the same groundbreaking technology as our flagship IEMs in our ergonomic aluminum shell to make it more accessible than ever.

Sound
In standard 64 Audio fashion, U6t is a balanced natural sounding earphone, slightly set apart from our other UIEM models by offering a softer presentation of a mix. Beautiful upper-mid imaging, realistically presenting instruments like guitars and piano as well as breathing life into saturated mid-bass mixes, especially when vocal focused. Using the various included apex modules and ear-tips allows the listener to further customize the sound of the U6t based on the needs of the music.

While looking towards U12t for sonic inspiration, our U18s influenced U6t's dark grey matte shell finish as well as its newly redesigned packaging. The understated shell design and classic black faceplate reflect what you can expect from the new generation of 64 Audio’s audiophile products.

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. U18s 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 U18s: 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 4 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.
