Description

Top-of-the-line reference in-ear monitor
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. This astonishingly complex system results in incredible detail, extension, and unmatched clarity across all frequencies
Sound
“This is a fast set that is still smooth, similar to driving a V8 luxury car at 60 MPH without noticing any road noise or bumps.”
– VSG (TechPowerUp)
“Overall, the U18t is 64 Audio’s more tonally balanced and linear monitor, with reference-like tuning. Like the Fourté, it outputs outstanding levels of micro-detailing, intelligibility and air to give it that signature top-end sound.”
– Smit Patel (Positive Feedback)
“The sound results are compelling and meet the highest demands of stage musicians, sound engineers and audiophile music listeners without restrictions.”
– Ulf Kaiser (Headphone Check)



64 Audio U18t Tzar 18 Drivers Universal IEM Earphones
Packed with an unbelievable 18-balanced armature driver per ear, the U18t is our top-of-the-line reference in-ear monitor. This industry-first design pushes the limits of what a reference monitor can be with incredible detail, extension, and unmatched clarity across all frequencies with a powerful low-end and extended sub-bass – just like its custom counterpart, the A18t. The A18t is preferred by critical listeners in engineering, monitoring and mixing, and audiophiles.
Each ergonomic shell is machined out of a solid piece of aluminium and finished with an elegant copper-patinated inlay on the faceplates.
Perfect for critical audiophile listeners
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. Aluminium billet shells are precisely milled into our signature ergonomic shape. The PVD Stainless Steel faceplates are finished with an Imperial Red enamel-like chip inlay.
