Fathom by Campfire Audio is an earphone made for audiophiles. Six custom-made balanced armatures deliver a detailed presentation with just the right touch of mid-band warmth that elevates vocal performance and offers a glowing musical experience.

Experience the culmination of nearly a decade of experience in the tuning and refinement of an all-balanced armature IEM. Fathom takes the long legacy of Campfire’s world-class precision and technical performance to its peak with our new six-B.A. internal architecture.

Utilizing a new dual mid-driver assembly, Fathom creates astounding richness, texture, and elevation to vocal performance, sharing every emotive detail from the artist to the listener. Paired with custom dual low and high balanced armature, Fathom offers top-to-bottom precision, detail, and resolution.

New Six-Balanced Armature Architecture

Fathom is equipped with six custom-made balanced armature drivers, each designed with a specific role in mind to enhance your listening experience. The configuration includes dual custom high-definition super tweeters for crisp, clear highs; a pair of custom mid-range drivers for accurate vocal and instrument reproduction; and dual custom BA woofers for rich, balanced bass. This setup is meticulously engineered to deliver precise sound reproduction across the entire frequency range.

Phase Harmony Engineering

At Campfire Audio, our philosophy regarding driver treatment informs a considered approach that emphasizes quality over quantity. In the arms-race to fit a higher and higher number of drivers into an earphone, we find that a results-driven technique to driver treatment produces superior results with less room for pitfalls and ever-expanding variables that can undermine product consistency.

One of the products of this approach is our Phase Harmony Engineering, that allows us to segment the frequency spectrum and assign these segments to specific drivers, and allows those drivers to apply their strengths to that area. But it doesn’t end there, using a combination of precision engineered driver housings and shell geometry, coupled with custom damping values we are able to physically shape the tuning and response of the drivers, and further, their interaction with one another. This driver-to-driver interaction is crucial to eliminating points of potential phase cancellation and creating the intangibles that don’t show on a frequency response curve; imaging, separation, resolution, and soundstage.
