Ponderosa Reviews

Phase Harmony Engineering

At Campfire Audio, our philosophy regarding driver treatment informs a considered approach that emphasizes quality over quantity.

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.

By using precision-engineered driver housings, shell geometry,and custom damping values, we are able to physically shape the tuning and response of the drivers.

The Ponderosa is a worthy addition to Campfire Audio’s universal IEM lineup and provides a familiar but unique experience to those who already own earphones from the brand.

Safe and Sound: Solid Body Design

Campfire Audio’s patented Solid Body Design allows driver installation directly into a single, precisely 3D printed ‘engine block’ that routes the sound to the listener and uses built-in geometry to tune and accent the drivers in an intentional and exact manner that elevates the listening experience for the user.

Additionally, this build style additionally improves the structural integrity within the earphone, and eliminates variables and points of failure that other forms of driver routing can be susceptible to.

    Fathom is precision engineered inside-and-out by the same engineering team that has brought you all Campfire IEMs for years. Leveraging our many in-house designs and advancements, Fathom is the new standard bearer for the all-BA branch of our IEM evolution.

  • Tuned With Intention

    This curve displays relative volume levels at each point across the frequency spectrum, reflecting Fathom's careful balance and refinement in tuning. Though FR curves are a great general guide, they can't convey technicalities like soundstage, imaging, layering, etc
