The Nio hybrid earphone features a 9mm dynamic driver and 8 balanced armature drivers. A sound signature characterized by deep lows and a rich 3-dimensional soundstage, Nio's smooth treble and natural warmth make listening to all genres of music an enjoyable experience. Each ergonomic shell is made from a solid piece of aluminum and finished with a striking blue abalone faceplate.

Exclusive technologies that challenge traditional in-ear monitor design for your absolute best listening experience.

Tia is a patented IEM design methodology that aims to eliminate unwanted resonance and distortion for a transparent and lifelike sound signature. TIA consists of three major components: open balanced armature drivers, the TIA single-bore design, and TIA acoustic chambers. Nio incorporates two major components of TIA: the TIA driver and the TIA single-bore design.

Apex is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations for Nio: mX, m15 and m20.

LID is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 9 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency responses across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.
