The detail and authenticity in the reproduction of voices and instruments of all kinds is breathtaking. The U18t do not demonstrate any weaknesses in the uppermost part of the frequency spectrum either. They operate with high speed and exemplary transparency, ensuring not only brilliance but also precise detail separation of the sound components involved. This also applies to the structure of the wide stereo panorama and surround sound. Here, everything is firmly in place, but can be just as reliably traced during modulations. I didn’t detect any unwanted harshness; rather, they offer the professional user the facility for an accurate balancing act, so decisions can safely be made about the desired degree of bite. The same applies to the use of effects like reverberation and echo, equalizers or dynamic tools from sound production.
For reference sound, the 64 Audio U18t takes the cake and frosts it twice. With a $2999 price tag, this expensive earphone guarantees the best sound won’t be had on the cheap. However, for those who can afford this level of sound, a world of high fidelity and uncompromising audio bliss await.
