The 64 Audio Trio is a universal-fit hybrid in-ear monitor with three drivers per side. A dynamic driver handles lows and mids, a balanced armature handles the high-mids, and a tia high driver handles the highs. The tuning is mildly warm and smooth, with impactful bass and open treble.
The design is fully tubeless, using the complete tia system with its acoustic chambers and single-bore design. Apex pressure relief is built into the shell and gives -15 dB of passive isolation. LID circuitry keeps the frequency response consistent regardless of source impedance. The FXC (Frequency eXtension Chamber) shapes airflow around the dynamic driver to improve midrange control.
The shell is milled from solid aluminum with a brushed aluminum faceplate in neutral grey. It comes with a black 3.5mm cable made of silver-plated OCC copper.
