The U18t took the audio world by storm with its whole 18-driver package. Now, it’s time for something bigger and better - the 64 Audio U18s! This in-ear monitor features the latest proprietary drivers, tia, Apex Core and LID technology as well as a whole new electronic crossover network for an unparalleled audio experience.

Go Tubeless with tia!
The 64 Audio U18t’s patented Tubeless In-Ear Audio (tia) system reduces unwanted resonance and distortion for a transparent and lifelike sound. This is achieved by allowing the tia balanced armature drivers to radiate freely in the single tia bore with no obstructions in front of the drivers.

Apex Sound & Comfort
The Air Pressure Exchange (Apex) Core allows seamless airflow to the aluminium shell that uses a perforated grill to prevent the obstruction of air for effortless reproduction of music. This patented vent releases air pressure for better comfort and lesser fatigue while enhancing noise isolation. This technology comes in three module variations: mX, m15 and m20.

Reliable with the Right LID
The different source amplifier output impedances of smartphones, DAC/Amps, Hi-Res Audio Players and more, can cause the frequency response to vary across devices based on the increase in resistance. A patented Linear Impedance Design (LID) circuit corrects the non-linear electrical resistance of the multiple driver sets to restore proper interaction with the source device. It preserves the desired sound signature while staying constant and reliable.

No Dampers, It’s Electrifying!
Old technologies like acoustic dampers merely blocked frequencies from reaching the ear instead of preventing it from reaching the drivers. This introduced distortion due to the vibration and air movement at higher volumes. The U18s uses an electrical low pass filter that reduces distortion while eliminating unwanted target frequencies before they reach the driver.

The Best of Nature & Science
Inspired by nature, the U18s is handcrafted in the USA from an aerospace-grade aluminium billet. This is CNC milled, sand-blasted, cut and anodised twice for incredible robustness. A striking fractal design makes it unique and stunning.

Premium Cables
A top-of-the-line IEM deserves a state-of-the-art cable. 65 strands of pure silver-plated OFC wires are combined together in an 8-braid cable. These are covered with a premium sheath to reduce microphonics and unwanted noise.
