Campfire Audio Balanced Armatures Earphones

Since 2015, balanced armature configurations have been a crucial part of the advancement and innovation of our lineup.

Working closely with some of the most experienced driver producers in the industry, we have worked to incorporate a wide range of custom balanced armatures into our designs.

Pairing unique combinations of differing drivers with our range of custom acoustic treatments and tuning chambers allows us to create a broad family of IEMs that are connected by the common strengths of these incredible drivers.

  • Fathom

    Our newest all-BA model featuring our new 6-BA internal architecture. This IEM carries offers a wonderful mid-range focus with indredible technical performance.

Describing Sound: Speed, Detail, and Resolution

Small, efficient, and lightning fast, balanced armatures excel at creating a fast, precise, and detailed sound signature. This lends them well to creating analytical, technical, and reference oriented tunings.

To some, armatures can at times come across cold, or overly technical sounding, and lacking some of the 'soul' found in dynamic drivers.

With our collective decades of in-house acoustic engineering experience, Campfire has successfully created all-BA IEMs that run a spectrum that include neutral, analytical signatures while also being able to bring in tunings that bring in warmth and musicality.

Perfectly Balanced: Pursuing the Best

At Campfire Audio, we have sampled, tested, prototyped, and implemented a seemingly endless number of balanced armatures and pure-BA internal architectures.

A certain driver may be implemented in a full-range context, or segmented to target a specific frequency band with our Phase Harmony Engineering. Some drivers may be doubled, tripled, or quadrupled (as seen in Ara's low driver assembly) to create changes in output, texture, and to emphasize a driver's strengths.

Most drivers are further customized using a range of acoustic treatments. Custom damping values, resonators, tuned acoustic expansion chambers (TAEC), and range of other techniques shape your drivers' performance and give each earphone a unique sonic character.
