64 Audio U18t

Packed with an unbelievable 18 balanced armature drivers per side, U18t is our top-of-the-line reference in-ear monitor. This industry-first design sits right at the boundary of what is physically possible in a UIEM. Released and developed alongside Fourté in 2016 it is the first IEM to integrate our patented tia technology with conventional IEM design, utilizing the tia high driver and single sound bore.

U18t achieves its quick bass response, while retaining enough sub-bass amplitude, by coupling eight modified mid-drivers for the low frequency band rather than using fewer/larger drivers. Another eight low-mid drivers are required to match that amplitude in the mids. The one high-mid + one tia high driver combination became the basis for 90% of our entire product range.

The extremely accurate response of U18t makes it perfect for critical audiophile listeners as well as mixing and mastering engineers. Aluminum billet shells precisely milled into our signature ergonomic shape. The PVD Stainless Steel faceplates are finished with an Imperial Red enamel like chip inlay.

Unmatched Audio Performance
The U18t sets the standard for in-ear monitors with an incredible 18 balanced armature drivers per side, pushing the limits of UIEM technology. Developed alongside Fourté in 2016, it was the first IEM to combine 64 Audio’s patented tia technology with a traditional design. This results in extraordinary detail, frequency extension, and unmatched clarity.

Precision-Tuned Drivers
Rather than relying on larger drivers, the U18t achieves its deep, responsive bass with eight modified mid-drivers dedicated to low frequencies. Another eight low-mid drivers ensure seamless mids, while a high-mid and tia high driver deliver exceptional accuracy across the spectrum.

Premium Craftsmanship
The U18t features an aluminium billet shell, precisely milled for comfort and durability. The PVD stainless steel faceplates are finished with an elegant Imperial Red enamel-like inlay, adding a refined touch. Designed for long listening sessions, its ergonomic shape ensures a secure and comfortable fit for any user.

SPC Eight-Braid Cable
For superior connectivity, the U18t comes with two premium SPC Eight-Braid cables: one with a 3.5mm single-ended connection and another with a 4.4mm balanced option. These cables enhance signal transmission while providing durability and flexibility for different listening setups.

Innovative Tia Technology
The U18t incorporates 64 Audio’s patented Tubeless In-Ear Audio (tia) technology, designed to eliminate unwanted resonance and distortion. This system includes open balanced armature tia drivers and a single-bore design, ensuring a transparent, natural sound signature with incredible resolution.

Customizable Sound with Apex
Equipped with 64 Audio’s Air Pressure Exchange (Apex) technology, the U18t features a patented venting system that reduces listener fatigue while maintaining high isolation. This allows for a more immersive soundstage and comfortable long-term listening. Four Apex module options (mX, m12, m15, and an exclusive PVD-coated stainless steel m20) let users tailor isolation levels and airflow to their preferences.
