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.
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. Each ergonomic shell is machined out of solid aluminum, anodized red, and finished with an elegant copper-patinated inlay on the faceplates.
