The 64 Audio Trió is a three driver fully-tubeless hybrid Universal In-Ear Monitor (UIEM). An audiophile UIEM in the sweet spot between reference-level clarity and a smooth sound signature perfect for extended listening. Each ergonomic Trió shell is machined out of solid aluminum. The internal chambers are precisely milled in order to house the tubeless drivers and shape their sound. Its understated neutral color palette is topped off with an elegant brushed aluminum faceplate.

64 Audio Trió design

One of the company’s fully tubeless UIEMs, the 64 Audio Trió features 64 Audio’s patented tia technology, integrated patented apex pressure relief, and patented LID circuitry. Trió relies on the Frequency eXtension Chamber (FXC) for superior mid-range control. The air volume of the back-vented dynamic driver is precisely controlled, delivering perfectly placed mid frequencies, giving vocals and instruments a remarkably natural sound.


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.

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

The 64 Audio Trió comes bundled with a multitude of tips, 3 pairs of TrueFidelity tips (S/M/L) and 3 pairs of silicone tips (S/M/L). The high quality included detachable cable terminates in a 3.5mm TRS plug. The package also includes a cleaning tool, dehumidifier, shirt clip, and hard shell protective case. The Tia Trio is finished in a durable anodised aluminium, ready for daily knocks and drops.
