The Trifecta 'Chrome Sky' offers a unique triple dynamic driver design for a spacious, open, and clean sound. Campfire Audio uses three proprietary ADLC (Amorphous Diamond-like Carbon) coated, rigid, lightweight drivers. The drivers are arranged in an equilateral triangle facing each other in the housing, delivering a powerful, coherent, and pure sound. The transparent skeleton-like housing gives a glimpse of the high purity copper and silver conductors. A truly special pair of headphones, packaged uniquely for quality music listening. The package includes three different connector cables, ensuring compatibility with almost any audio source.
