A radical new driver design was needed to achieve a wider frequency range, realistic reproduction, and a more balanced sound. At the heart of this innovative new driver assembly is the all-new Dual-Diaphragm Balance Armature Driver from Knowles. By employing a single-coil operating two individual diaphragms, the design is akin to the twin-cylinder engine – delivering more horsepower and smoother operation than one with a single, larger piston. Compared to a traditional BA model with a single, larger diaphragm, this all-new design incorporates two chambers, each housing its own diaphragm and drive rod actuated by a single coil. The result is a higher, more powerful output for its size than any other BA driver design while expressing a warmer and more natural mid-range in key areas of the music.

Boasting hybrid diaphragms and housed in a Radial Venting Acoustic Chamber 3D printed acoustic chamber, this all-new design by Campfire Audio, creates a faster and more powerful low-frequency response without unnecessary pressure or bass bloat. Each dynamic driver is vented through a specially designed opening located at the face of the driver. This acoustic chamber dramatically improves the expression of the drivers, and creates a larger soundstage, while preserving the unique sound of the dynamic driver.

PATHFINDER comes with three different flavored cables to cover all unbalanced and balanced headphones connections (2.5mm, 3.5mm and 4.4mm.) The all-new Silver-Plated Copper Litz Cable consists of four conductors arranged side by side, designed to provide the most transparent and extended sounds possible. The soft-touch molded jacket that wraps around each conductor ensures both flexibility and durability. At the same time, a flat cable design prevents tangling, can be wound for easy storage and offers minimal cable distortion. The cable terminates with a robust metal connector housing. Elsewhere, the custom beryllium/copper MMCX connectors provide more resilience against wear and tear, compared to regular brass connectors, while also offering a more robust mating mechanism. This harder material selection extends the life of the component and the earphone.
