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.

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, dual 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 Dynamic Driver.
