Campfire Audio Grand Luna In-Ear Monitor

PlanarBA hybrid with 14 mm planar for lows/mids, dual balanced armatures for highs, AAOI housing, and hand-built in Portland, OR

Grand Luna is a precision-engineered in-ear monitor that blends a hand-treated and textured stainless-steel lid with Campfires AAOI 3D-printed housing. The transparent shell shows the internal architecture in a deep red finish.

A 14 mm planar magnetic driver handles low and mid frequencies, delivering speed, transient accuracy, and dynamic impact, while two premium balanced armatures extend the highs smoothly to 30 kHz. The tuning aims for separation and imaging without the harshness sometimes associated with planar designs.

The new six-conductor silver-and-copper interconnect uses a swappable termination system: 3.5 mm single-ended, 4.4 mm balanced, and a USB-C DAC termination using Cirrus Logics CS43131. Aluminum hardware, soft PVC jacketing, and adjustable chin-cinch round out daily usability.
