Astell&Kern PATHFINDER Hybrid IEM

1 Year Local Warranty.

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.



Internal Structure


Precision-Milled Aluminum Shell

The precision-milled aluminum shells made with high-quality aluminum are anodized into a pitch-black “Night Sky” colour.

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 Chamber’ 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. Find out more about the amazing performance of this brand-new Dual Chamber BA Driver unique to PATHFINDER.


Rich and Visceral Bass, All-New Dual Custom 10mm Dynamic Drivers

Dual Custom Dynamic Drivers with PU + LCP Hybrid Diaphragms present a clean and balanced low to midrange with quick response.

The Dual 10mm Dynamic Drivers contained in the innovative 3D-printed chamber design provide a rich and high-definition low to midrange. The acoustic chamber is an all-new design by Campfire Audio, creating a faster and more powerful low frequency response without unnecessary pressure or exaggeration.

Each dynamic driver is vented through a specially designed opening located at the face of the driver. This new design dramatically improves the expression of the drivers. With this design, we are able to create a magnificent low-note frequency while preserving the unique sound of the dynamic driver.


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.
