FiR Audio Projekt K Universal

Redefining the Pinnacle of Personal Audio

The Project K represents FiR Audio’s ultimate achievement in in-ear monitor design — a flawless fusion of cutting-edge engineering, elegant aesthetics, and uncompromising sound quality.

At its core is a meticulously tuned 5-driver hybrid configuration: a powerful 9 mm Kinetic Bass dynamic driver delivers deep, physical low-end response, while four OpenDriver balanced armature drivers cover the midrange and highs with breathtaking clarity and openness. A specialized Sound Reflector enhances high-frequency detail, pushing resolution to new heights.

Housed in precision-machined titanium shells, Project K is as durable as it is lightweight. The stunning blue copper faceplates, protected under sapphire glass, elevate the design to true collector status — every detail exudes craftsmanship and sophistication.

To tailor the sound to your personal preference, the included ATOM venting system comes with Gold and Xs modules, providing pressure relief and tunable airflow. Additional modules are available separately.

Internally, premium silver wiring ensures pure signal transmission, while a white leather protective case offers both luxury and protection on the go.
