The 64 Audio U18s are in-ear headphones equipped with 18 balanced armatures on each side. The result is live deep bass, transparent mid frequencies, impressive high frequency extension, as well as distinct depth gradation and an expanded soundstage. The modular Apex technology reduces air pressure in the ear canal and delivers flawless sound quality.
Features:
- Tia driver for high frequencies
- 1 balanced armature for mid-high frequencies
- 8 balanced armatures for mid frequencies
- 8 balanced armatures for low frequencies
- Tia, ApexCore, LID technologies
- 4-way passive crossover
- Filters: -20 dB, -15 dB, -10 dB
- Solid aluminum housing
- Premium silver cable
As expected from headphones in the top tier, the 64 Audio U18s create an impressive soundstage. The U18s combine patented drivers, LID technology, and a new crossover network to deliver unique and exceptional listening quality. This intricately designed system offers incredible detail, extension, and unmatched clarity across all frequencies.
The headphones, typical of 64 Audio models, boast a wide stereo panorama. The soundstage is constructed more on height and width rather than depth. The U18s excel at creating depth in the soundstage, providing an excellent picture of the localization of planes and their separation. The warmth of the bass range moderately permeates the mid-bass and lower midrange junction, ensuring sound integrity and natural perception. The headphones manage to maintain the variability and plasticity of the sound, even through some rounding and elasticity of the low frequencies. The dynamic low-end is lively, and the rich array of drivers ensures excellent extension.
The 64 Audio U18s offer fast response while maintaining sufficient low-frequency amplitude, thanks to the connection of eight modified dynamic drivers for the low-frequency range instead of using fewer/larger drivers.
Tia Technology
The special design of the drivers and housing without acoustic sound tubes provides transparent and realistic sound. The system reduces unwanted resonance and distortion, allowing the Tia high-frequency driver to sound freely in one large sound tube. The U18s are equipped with two main elements of the Tia system: the Tia driver and the single-bore design.
Apex Core Technology
The technology aims to reduce listener fatigue by alleviating excessive air pressure in the ear canal. This ventilation allows musicians and music enthusiasts to comfortably use the headphones for longer periods. Apex comes in three module options for the U18s: mX, m15, and m20.
The 64 Audio U18s are handcrafted in the USA from top-grade aerospace aluminum billet. CNC milling, sandblasting, in-flight cutting, and dual anodizing result in a stunning fractal design inspired by nature.
The headphone housing mimics the shape of the ear canal. The model is designed not only for audiophiles but also for musicians. The 18 drivers in the configuration are distributed as follows: 8 handle the low-frequency range, another 8 reproduce mid frequencies, one is responsible for the upper midrange, and the last one covers the high-frequency range.
