Discover the pinnacle of audiophile craftsmanship with the 64 Audio tia Trio In-Ear Monitors. Striking the perfect balance between reference-level clarity and a velvety smooth sound signature, these monitors are designed to offer an exceptional auditory journey that can be enjoyed for extended listening sessions without compromising on sonic excellence.

Impeccable Craftsmanship in Every Detail

Meticulously designed, the tia Trio UIEM stands out with its ergonomic shell, expertly machined from solid aluminum. The internal chambers are precision-milled to cradle the tubeless drivers, meticulously shaping their sound characteristics. With an understated yet elegant brushed aluminum faceplate, the tia Trio exudes sophistication in its neutral color palette.

Unleash the Power of Patented Technology

  • tia Technology: The Heart of Unprecedented Sound

    At the core of the tia Trio's acoustic brilliance lies the patented tia technology. This innovative design methodology revolutionizes the audio landscape by eliminating unwanted resonance and distortion, resulting in a transparent and lifelike sound signature. Comprising open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers, this technology offers unobstructed radiance for each driver, ensuring an unparalleled auditory experience.

  • Apex Pressure Relief: All-Day Comfort

    Experience music like never before, with the integrated patented apex pressure relief. This venting system masterfully releases air pressure from the sealed ear canal, maintaining standard IEM levels of isolation. This not only enhances comfort during extended listening sessions but also ushers in a more realistic soundstage, elevating your immersion into the music.

  • LID Circuitry: Consistency Redefined

    Say goodbye to variable frequency responses caused by source amplifier output impedance. The patented Linear Impedance Design (LID) circuitry resolves non-linear electrical resistance, ensuring consistent and reliable sound reproduction. Whether you're using a smartphone, DAC/amp, or any other source, the tia Trio preserves the desired sound signature for an uncompromised sonic journey.

With a sensitivity of 104dB @1kHz @1mW, these monitors empower your music with stunning detail and clarity.

The Tia Trió does everything I enjoy about hybrid driver IEMs, including excellent bass slam and definition, while at the same time demonstrating a carefully refined tuning. It has a moderate 'V-shaped' sound signature, with a slight midrange recession, however it's done so in such a tasteful way that it's bound to be agreeable for anyone who enjoys modern genres. Importantly, the hybrid style adds the benefits of dynamic driver bass slam, but it never feels overdone to the point of encroaching on the mids and crowding out other instruments in the mix. This means the bass is tight, well-controlled, and hits with authority. I'm also impressed with the lack of sibilant emphasis throughout the consonant range at 8.5khz. There's enough energy there to impart clarity and detail, but it's able to resolve consonant sounds smoothly, without any grain or etch. Overall, this is an exceptional IEM.
