64 Audio Introduces U18s Earphones

64 Audio revolutionized the IEM industry in 2016 with its world class reference level U18t, the world’s first 18-driver earphone. Now, with the introduction of 64 Audio U18s, they have taken the heritage of the 18 driver platform and further pushed the envelope of innovation in sound and design. U18s combines proprietary drivers, LID technology and a new electronic crossover network to deliver a uniquely exceptional listening experience.


Handcrafted in the USA from aerospace-grade aluminum billet. CNC milled, hand blasted, fly cut, and twice anodized – the result is a striking fractal design that is inspired by nature itself.




Tia – A tubeless design that reduces resonance for a transparent and lifelike sound signature.


Apex – Alleviates listener fatigue by releasing air pressure sealed in the ear canal. This venting enables musicians and music enthusiasts to listen more comfortably for longer – only from 64 Audio.


LID – Enables a consistent, reliable sound regardless of audio source.
