Hybrid IEM redefined

Astell&Kern has teamed up with Campfire Audio, a U.S. designer and manufacturer of premium hand-built earphones, to introduce the PATHFINDER in-ear monitor (IEM). Following the successful SOLARIS X collaboration, the all-new jointly developed PATHFINDER takes hybrid IEM design to another level. These sophisticated earphones feature advanced Dual-Chamber Balanced Armature (BA) Driver technology to reach new heights in audio realism

World’s First Dual-Diaphragm Balanced Armature Driver

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.

Dual-chamber driver design

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.

BA driver with T.A.E.C. technology

Further custom-dual BA drivers focus on delivering clearer and more precise high-frequency reproduction. Benefitting from Campfire Audio’s patented Tuned Acoustic Expansion Chamber technology (T.A.E.C.) technology, this design optimizes the performance by adjusting the volume of space available in front of the driver and provides a direct passage from the driver to your ear. This clever design extends high frequencies without sibilance or fatigue, delivering unsurpassed clarity and a smooth top end.

Dynamic drivers with Radial Venting Technology

Delivery of the rich and visceral bass sounds, while bringing greater definition to the lower midrange, arrives courtesy of dual-custom dynamic 10mm drivers. 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.

Silver-Plated Copper Litz Cable design

PATHFINDER comes with three different flavoured 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 ensures both flexibility and durability, while a flat cable design that prevents tangling can be wound for easy storage and offers minimal cable distortion.

Premium design philosophies

The brushed stainless steel-hewn inlay on PATHFINDER combines the two design philosophies of each company. Astell&Kern’s ‘light and shadow’ recognisable motif is present and correct, while Campfire Audio’s connection with nature is represented by this six-sided ‘Mountain Peak’ contour. Precision engineered, this design motif displays the value of the premium craftsmanship and innovation that Campfire Audio and Astell&Kern are renowned.
