64 Audio U18t 18 Driver Reference In-Ear Monitor (2025 Edition)

The U18 is 64 Audio’s flagship reference tuned offering, offering 8 drivers focusing on the bass frequencies, 8 drivers focusing on the midrange and a duet of Tia drivers focusing on the highs and mids. The 18 drivers are secured in an ergonomic aluminium shell, and the inlaid copper patina faceplate finishes off the design with flair. The U18 also features Apex technology, which relieves air pressure created by speakers in an enclosed environment. The U18 comes bundled with a 48 inch, 2-pin detachable cable terminating with a 3.5mm plug, protective case, a extensive set of silicone tips, the Apex m20 module and the Apex M15 module, shirt clip, and cleaning tool.

The U18 Tzar’s delivers an accurate, reference level sound for critical listening. The earphones are airy, detailed, and exhibit crisp highs, yet have powerful bass and smooth, intimate vocal presence. The balance of these elements ensure the U18 is suited for any genre of music, faithfully representing the music as the artist intended. For a more aggressive and energetic sound, consider the 64 Audio Tia Fourte.
