Quality components. Fine craftsmanship. World-class audiophile earphones.


Ken Ball started Audio Line Out in 2009, hand-building some of the most excellent niche audio cables in the world. His efforts grew that company from his basement into ALO audio; of the most well-regarded names in personal audio. A long line of successful amplifiers and cables spread and cemented that reputation, which remains firmly in place today.

Campfire Audio springs from the same passionate focus on refined audio reproduction as ALO audio. With a small team of highly skilled and dedicated craftspeople, we continuously experiment with materials and techniques to create something unique and special for the people who care most about it. With determination and focus, prototypes turn into world-class earphones. Each model in our earphone line is designed and assembled by hand in our Portland, Oregon workshop; our earphones are second to none in performance and finish.
