Unveiled by Campfire Audio: Cutting-edge and hybrid earphones named the Grand Luna
Campfire Audio Introduces the Grand Luna IEMs: A New Hybrid Planar-Balanced Armature Earphone
Campfire Audio, a Portland-based company, has announced the release of their latest innovation in earphone design - the Grand Luna IEMs. These hybrid earphones combine a customized 14mm planar magnetic driver with two precision-tuned balanced armatures, marking Campfire’s first planar-balanced armature hybrid model.
Key Technical Specifications
The Grand Luna IEMs boast several impressive technical specifications. With an impedance of 13Ω, they are suitable for most portable sources and headphone amplifiers. The frequency response ranges from 5 Hz to an unprecedented 30 kHz, thanks to the balanced armatures. The Sound Pressure Level (SPL) is 94 dB at 1 kHz with 33 mVrms input. Total Harmonic Distortion (THD) is less than 0.5%, indicating clean sound reproduction.
The driver configuration includes a central 14mm planar magnetic driver handling low and mid frequencies, delivering rich bass and rapid transient response, and two balanced armatures managing high frequencies with speed, detail, and resolution. This combination results in a rich, bass-heavy yet detailed and smooth sound with a wide dynamic range and minimal harshness or sibilance.
Unique Features
The Grand Luna IEMs offer several unique features that set them apart. Each IEM has a vibrant, internally dyed red, externally transparent, 3D-printed shell. The hand-assembled earphones feature a brushed stainless steel faceted lid and a flame-treated colorful CA logo.
The earphones come with a new modular cable system that supports 3.5mm single-ended, 4.4mm balanced, and USB-C DAC terminations, enhancing versatility. The built-in USB-C DAC module uses a high-end Cirrus Logic CS43131 Master HiFi chip, supporting 32-bit/384kHz PCM playback and DSD256. This allows direct digital connection to compatible devices for high-resolution audio processing without an external DAC.
Availability and Pricing
The Grand Luna IEMs will be available from August 8, 2025. Each pair retails for $1,399 / £1,399 / €1.399. The accessories include a new high-purity silver and copper cable, multiple eartip options, a "Blood Moon" red leather magnetic carry case, microfiber cleaning cloth, and a ten-year anniversary lapel pin to mark Campfire’s milestone.
With the Grand Luna IEMs, Campfire Audio has advanced its hybrid planar IEM technology, catering to audiophiles seeking rich bass, detailed highs, excellent dynamics, and convenience via its built-in DAC and modular cables.
These Grand Luna IEMs from Campfire Audio, available from August 8, 2025, are not just another pair of in-ear monitors, they are high-end earphones featuring a hybrid design that incorporates planar magnetic drivers and balanced armature drivers. The technology-rich smartphones of today can benefit from this innovation, as the Grand Luna IEMs come with a built-in USB-C DAC that supports 32-bit/384kHz PCM playback and DSD256, connecting directly to compatible devices for high-resolution audio processing, making them a fantastic choice for tech enthusiasts and music lovers alike.
