Campfire Audio is a Portland, Oregon-based audio company founded in 2015 by Ken Ball, who also runs the cable and amplifier maker ALO Audio. The brand specializes in high-end in-ear monitors, with every IEM hand-assembled at its workshop in Portland. Its lineup spans balanced armature, dynamic driver, hybrid, and planar magnetic designs, alongside custom-fit IEMs, cables, and accessories.

The company is known for distinctive industrial design — including ceramic-coated metal shells finished in CeraKote — and proprietary acoustic engineering such as the Tuned Acoustic Expansion Chamber (T.A.E.C.) and beryllium copper MMCX connectors. Models like the Andromeda, Solaris, Ara, Ponderosa, Cascara, Trifecta, and Onyx have built a reputation in the audiophile community for detailed, technical sound and bold styling.

Alongside its universal-fit lineup, Campfire Audio offers a custom IEM program crafted from impressions taken by audiologists. The brand has cultivated a strong following among portable audio enthusiasts and reviewers on sites like Head-Fi, where its releases are routinely covered and discussed.
