64 Audio Tia Trio IEM

*WARRANTY: 1 Year Local Warranty

Tia Trio

The perfect in-ear monitor for listeners looking for the sweet spot between reference-level clarity and a smooth sound signature for extended listening. The tia Trio is a great earphone for audiophiles seeking a clear, laid back, 3D sound in any genre.

Tia Trio features our complete, three-part tia system housed in an ergonomic shell, machined from a solid piece of aluminum and finished with elegant, brushed aluminum faceplates.



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

tia Trio features the following unique technology:


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

    Tia Trio features all three elements of our complete tia system: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers.

    Tia Driver

    An open balanced armature speaker design for realistic resolution and transparency. By opening a balanced armature, the diaphragm becomes fully unobstructed, reducing resonance in the IEM and allowing sound to travel more naturally to the ear.

    Tia Single Bore

    A huge advancement in eliminating unwanted tube resonance. The large bore itself serves as a sound-shaping chamber and aids the tia high driver in delivering a linear and coherent frequency response. The short sound path provides remarkable high-frequency extension and smoothness. The large single bore also allows for easier maintenance.

    Tia Acoustic Chambers

    This specific structural design optimizes driver performance with precise placement of each internal component. The exact placement of each driver delivers what many describe as a three-dimensional, holographic soundstage.


    Only from 64 Audio, 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.

    Apex, or Air Pressure Exchange, is a pneumatically interactive vent that releases air pressure in a sealed in the ear canal. Apex comes in two variations, m15 (-15dB) and m20 (-20dB), tia Trio features an internal m15 apex module.

    Alleviate Listener Fatigue

    When you seal a miniature speaker in an ear canal, the air inside becomes trapped. Apex relieves this air pressure, allowing the eardrum to move naturally, so you can comfortably listen longer.

    Extend The Soundstage

    Freely moving air extends the soundstage and provides a more natural listening experience. It also preserves bass frequencies and helps the listener distinguish individual instruments.

    High Fidelity Listening

    Apex lowers decibel levels while preserving the clarity of the sounds around you, so you can stay aware of external sounds, without distracting from your music.


    Enables a consistent, reliable sound regardless of audio source.

    LID, or Linear Impedance Design, enables a consistent, reliable sound regardless of what source. This proprietary circuit corrects the non-linear impedances of the drivers, restoring proper interaction with the source and preserving the desired sound signature.

    Whether you're a musician plugging into a variety of gear at different gigs or studios, or an audiophile listening from low-impedance sources, LID ensures your IEMs are delivering the desired sound signature consistently.

    And like all our IEMs, this model can be used with a wide range of personal audio devices as well as all hard-wired and wireless monitor systems.
