The 64 Audio Nio is the company’s first high driver-count hybrid UIEM featuring a 9mm dynamic driver and 8 balanced armature drivers. The drivers and other patented components are housed in an ergonomic shell machined out of solid aluminum. Similar to some of the other unique 64 Audio faceplates, Nio is finished with a naturally sourced striking blue abalone faceplate making each pair truly unique.

Apex MX module

The 64 Audio Nio features an exclusive new Apex Module, called the “MX” module, which allows you to achieve a more open sound and a tuning more suited to reference listening. Along with the other Apex modules included with the Nio, this gives you the choice between a thicker, warmer response or a more reference tuning. 64’s Linear Impedance Design ensures a consistent experience across different sources, and the Nio features a new leather carrying case and a stunning Abalone shell faceplate.

64 Audio Nio – sound signature

With a sound signature characterized by extended lows and a rich 3-dimensional soundstage, Nio’s smooth treble and natural warmth will provide hours of enjoyable listening for all genres of music. With the included variety of tips and apex modules you can take Nio from a saturated tube-like warmth all the way to a neutral reference monitor tonality.


Exclusive technologies that challenge traditional in-ear monitor designs to give you the absolute best listening experience

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. Apex comes in three module variations for Nio: mX, m15 and m20.

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