The Hybrid IEM Redefined
Campfire Audio and Astell&Kern have earned the recognition of audiophiles around the world thanks to their excellent technology introduced with the first collaboration model, AK Solaris X, which is a celebrated product that recreates the deep, rich sound of Astell&Kern.
Now, Astell&Kern and Campfire Audio join forces once again to present PATHFINDER, a new hybrid IEM that offers amazing technology and sound.
Astell&Kern and Campfire Audio take innovation to a new level by combining their advanced technologies and designs to create a product worthy of the name PATHFINDER.
To realize this dream, they repeatedly tested numerous designs to produce a structure different from existing IEMs and added an innovative Dual-Diaphragm Balanced Armature Driver, finally achieving the best sound.
Enjoy a unique experience through PATHFINDER, a more advanced Hybrid IEM.
About Campfire Audio
Campfire Audio springs from a passionate focus on refined audio reproduction. Each model in our earphone line is designed and assembled by hand in our Portland, Oregon workshop; our earphones are second to none in performance and finish. With a small team of highly skilled and dedicated craftspeople, we continuously experiment with materials and techniques to create something unique and special for the people who care most about it.
The Combination for Perfect Balance
A completely new IEM design was needed for a wider frequency range, realistic reproduction, and a perfect balance.
To achieve this, PATHFINDER has a new Dual-Diaphragm Balanced Armature (BA) Driver from Knowles for the key part of the midrange, two BA drivers for high frequencies, as well as two dynamic drivers with hybrid diaphragms that create bass and midrange.
A Radial Venting Acoustic Chamber, newly developed by Campfire Audio, is applied to the two Custom 10mm Dynamic Drivers. The 3D-printed chamber design naturally expresses the intense low-frequency sound produced by the two dynamic drivers while preserving the unique sound of the BA driver.
Precision-Milled Aluminum Shell
The precision-milled aluminum shells made with high-quality aluminum are anodized into a pitch-black “Night Sky” color.
The stainless steel parts and aluminum shells used in the body increase the product's durability and suppresses unnecessary vibrations for minimal noise and offers a secure fit so that users can enjoy a comfortable audio environment.
New Level of Performance, Custom Dual Balanced Armature Drivers + T.A.E.C.
The newly customized Dual Balanced Armature Drivers present clearer and more precise expressions with T.A.E.C. (Tuned Acoustic Expansion Chamber) that expresses high frequencies without fatigue or sibilance through a specially designed audio technology.
The World's First, All-New Dual-Chamber Balanced Armature Driver Technology
To create a higher quality acoustic performance and listening experience, we needed a new technology that previous products did not have.
Knowles’ new ‘Dual-Diaphragm’ Balanced Armature Driver, used for the first time ever in PATHFINDER, is an innovative driver in which a single coil operates two individual diaphragms. It’s like a twin cylinder engine – delivering more horsepower and smoother operation compared to one with a single, larger piston.
Compared to a traditional BA with a single, larger diaphragm, the all-new design incorporates two chambers, each housing its own diaphragm and drive rod actuated by a single coil, resulting in a higher, more powerful output for its size than any other BA and is excellent at expressing a warmer and more natural midrange.

Beryllium / Copper MMCX Connections
Custom Beryllium Copper MMCX connectors are more resilient against wear and tear than regular brass connectors, providing a robust mating mechanism; one that is typically made from soft brass.
This selection of a harder material extends the life of the component and the earphone.
Silver-Plated Copper and Flat Cable Design
PATHFINDER comes with three silver-plated copper cables allowing the earphones to reach their full performance potential. The silver-plated OFC copper Litz cable is a newly produced flat cable, with enameled silver-plated copper wire conductor to offer clearer, extended sounds.
The flat cable prevents tangling, can be wound for easy storage, and has minimal cable distortion.
It is over-molded for increased durability and finished with a metal housing.
Featured Technologies
T.A.E.C. - Tuned Acoustic Expansion Chamber
Our tuned acoustic expansion chamber technology allows us to deliver extended high frequencies without sibilance or fatigue. We optimize our driver performance by adjusting the volume of space available in front of the driver. This is superior to the typical "Tube+Dampener" system because it provides a direct passage from the driver to your ear, which results in unsurpassed clarity and extension.
Radial Venting Technology - 3D Printed Acoustic Tuning for Dynamic Drivers
This allows our dynamic drivers to vent to the entire circumference of the driver. The practical impact is a larger soundstage and more presence without increasing pressure or bass bloat.
3D Printed Interior - Carefully Designed for Optimum Sonic Performance
Close attention to detail is critical to delivering you the superior musical experience from our earphones. Solaris features an acoustically optimized interior model that allows each driver to deliver the very best sound quality. When heard together, the drivers offer a seamless musical experience as a result of this process.
