Product Description

64 Audio – U18s

A revolutionary design inspired by nature

64 Audio truly revolutionized the game with the original 64 Audio – U18s, world-first 18-balanced-armature earphones. The product design has now taken the heritage further and kicked the envelope of innovation in sound and design beyond what you may have imagined.

Combining proprietary drivers, LID technology, and a new electronic crossover network, the listening experience is exceptional. Handcrafted in the states of America with aerospace-grade aluminum billet, then CNC milled, sandblasted, fly cut, and twice anodized – the U18s have a striking fractal design that is inspired by nature itself.

18 Drivers and 4-way passive crossover technology

To bring out the highest resolution and extract every single detail in the music, the U18s house 18 balanced armature drivers. There are 8 drivers for the lows and 8 for the mids, and another 1 for the higher mid-range plus 1 driver that handles the rest in the upper frequencies, like a small orchestra in your ears.

The result of this 18-driver configuration is an extremely wide frequency response range and high sensitivity measured at 106 dB/mW @ 1kHz.

64 Audio – U18s LID technology

Lid, or Linear Impedance Design, empowers a steady, dependable sound regardless of what source. This exclusive circuit rectifies the non-linear impedances of the drivers, reestablishing legitimate interaction with the source and preserving the desired sound signature.

Whether you are an artist stepping into a variety of gear at your different gigs or studios, or an audiophile listening from low-impedance sources like your Laptop. Lid guarantees your IEMs are conveying the specified sound signature reliably and deliver desirable performance at all times.

 64 Audio – U18s Tia resonance-free design

With a tubeless design, resonances are reduced to a minimum level. Such helps offer the most accurate and straightforward sound signature. The tia framework comprises three major components: open adjusted armature tia drivers, the tia single-bore structure, and tia acoustic chambers.

The U18s highlight two major components of the tia framework: the tia driver and the tia single-bore design. Tia Driver features an open balanced armature speaker design. Which aims at resolution and transparency while being extremely realistic in sound production. The open balanced armature design allows the diaphragm to be not obstructed, giving its full swing and reducing resonance.

It is enabling the sound to be traveling much more naturally and transparently to your ears.

Apex venting technology

You may have experienced pressure sealed inside your ear when wearing a custom monitor or a high-grade earphone. But this does not happen on the U18s. The design alleviates the listener’s fatigue by guiding away air pressure. It trapped in the ear when you wear the earphones. This design allows musicians and enthusiasts to listen more comfortably for long durations. Without any fatigue caused by the closed seal.

Custom in-ear monitors provide enhanced isolation and help musicians hear their mix more clearly. Even at lower volume levels than studio monitors or earbuds. Apex lowers the decibel levels while retaining sound qualities and clarity. So If you play on stage you can connect to the audience while protecting your hearing.
