Nio
Nine Driver Universal In-Ear Monitor
Made in the USA
64 Audio’s first high driver-count hybrid, Nio is a universal-fit earphone featuring a 9mm dynamic driver and 8 balanced armature drivers.
With a versatile sound signature characterized by extended lows and a rich three-dimensional soundstage, Nio’s powerful warmth and smooth treble will provide hours of pleasurable listening for all genres of music. This is an earphone that is unabashedly fun — and thanks to interchangeable Apex modules, you can instantly switch from enjoying extra bass to a neutral sound signature.
Each ergonomic shell is machined out of a solid piece of aluminum and finished with a striking blue abalone faceplate.
SOUND
Nio is incredibly versatile, delivering two distinct listening experiences in one IEM.
TECHNOLOGY
Duo features exclusive technologies that challenge traditional in-ear monitor designs to give you the absolute best listening experience.





- The m20 module (-20dB noise isolation) offers the greatest sub-bass shelf, with the type of isolation you’d expect from a conventional IEM, minus the ear fatigue.
- The m15 module (-15dB noise isolation) is fitted to Nio by default. Enjoy a powerful warm sound, while hearing some of your surroundings.
- The mX module (-10dB noise isolation) transforms Nio into a neutral IEM, significantly attenuating bass, opening up the soundstage, and proving its incredible versatility.
