A smooth and satisfying musical presentation in a custom fit earphone. Supermoon takes its 14mm custom planar magnetic driver and creates velvety low-end, textural mids, and detailed highs — a uniquely meditative and tranquil experience you can enjoy effortlessly for hours. The driver's two-micron thin diaphragm erupts with spontaneous musical dynamics, while delivering notably low non-linear distortion.
Planar Sound
Now in a Custom IEM
A newer development in the world of IEMs, the Planar Magnetic driver is known for its accuracy, speed, and power. Due to its large, flat, and fast-moving diaphragm, it can create both a sense of power and a revealing, subtle nuance and complex reproduction that traditional balanced armatures and dynamic drivers can’t. Our all-new Planar design has overcome the traditional challenges — namely, poor efficiency and sensitivity — to bring an incredible sonic experience to IEM users.
Supermoon is the first Campfire IEM to implement a full-range, 14mm planar driver, giving it a truly unique sound signature within our broader line-up. The combination of the diaphragm's size and speed creates a rich, smooth, and accurate low-end while maintaining crisp, resolving detail throughout the frequency spectrum and sparkling high-end detail.
Safe & Sound
Campfire Audio’s patented Solid Body Design allows driver installation directly into a single, precisely 3D printed ‘engine block’ that routes the sound to the listener and uses built-in geometry to tune and accent the drivers in an intentional and exact manner that elevates the listening experience for the user.
Each custom fit in-ear monitor begins with an ear impression. This impression is scanned into our system. Through our signature process, we manipulate the interior acoustic chambers of the Supermoon design; arranging them in optimal position inside the shape of the impression. This also allows us the opportunity to optimize the performance of the IEM for your ear, resulting in a better-sounding IEM.
Additionally, this build style additionally improves the structural integrity within the earphone, and eliminates variables and points of failure that other forms of driver routing can be susceptible to.
Whether you're listening at home, flying coast to coast, or performing on stage, you'll get a great fit bespoke to your ears — no eartips needed. Campfire offers two custom fit style options to fit everyone's needs.
