Campfire Audio Grand Luna - Planar Hybrid IEM Earphone

 

Introducing Grand Luna by Campfire Audio, a groundbreaking addition to our in-ear monitor lineup. Designed with a unique hybrid planar-balanced armature driver configuration, Grand Luna delivers an extraordinary listening experience that combines precision, depth, and musicality. Its custom-tuned 14mm planar driver anchors the low and mid frequencies, producing powerful impact, fast transient response, and smooth dynamics. Complementing this, two premium balanced armatures extend the highs with clarity and detail, reaching an impressive 30 kHz while maintaining an easy, non-fatiguing character.

The AAOI 3D-printed housing with a vibrant transparent red finish not only enhances acoustic performance but also highlights the striking internal design. Externally, the earphones feature a hand-treated stainless steel lid with flame-induced gradients and a brushed finish, blending durability with artistic detail. Grand Luna also introduces our new swappable cable system, allowing effortless changes between 3.5mm, 4.4mm, and USB-C DAC terminations. With a six-conductor silver and copper mix, the cable ensures balanced tonality and excellent resolution. For audiophiles seeking detail, impact, and immersive staging, Grand Luna sets a new benchmark.

 

Features

  • Updated 14mm planar magnetic driver
  • 2x high-frequency balanced armatures
  • Custom matrix MMCX connectors
  • Internally dyed transparent shell
  • Flame-treated CA logo
  • Brushed stainless steel lid
  • Matte finish stainless steel nozzle
  • New CA interconnect cable system with swappable terminations
  • Vented housing for even air-pressure and driver performance

 

The Planar Edge

Featured in different iterations in two of our well-loved planar IEMs, Astrolith and Supermoon, this new version is the cutting edge of planar technology. Customized and carefully tuned by Campfire’s acoustic engineering team, Grand Luna’s planar targets low and mid frequencies and applies its signature, vast dynamic range and rapid transient response. A unique combination of size and speed, this 14mm planar creates rich impact and texture alongside accuracy and precision that maintains separation and imaging. Campfire’s experience in developing planar magnetic IEMs is applied to create a unique sense of smoothness and easy-listening, limiting planar technology’s tendency to approach harshness and sibilance.

 

A New Blend

A first in Campfire IEMs, Grand Luna’s two premium balanced armatures orbit its central planar driver to accent and contribute their classic speed, detail, and resolution. The culmination of this driver combination and Campfire’s careful acoustic engineering, bringing Grand Luna’s high frequency extension to incredible heights of 30 kHz, adding an ethereal resonance while impressively defying a fatiguing high end.

 

Hand-Forged Detail

Grand Luna’s exterior finish features a hand-treated and textured stainless steel lid. First delicately flame-treated by hand to achieve a colorful gradient, and then carefully brushed by Campfire technicians to remove undesirable edges and blemishes, leaving behind a beautiful, organic CA logo and a pleasing, durable, brushed finish. This meticulous process reflects the craftsmanship and care put into every facet of Grand Luna; from engineering, to hand-assembly, to QC, packaging, and shipping, all done with care by our small team in Portland, Oregon.

About Campfire Audio

Portland-based maker of hand-assembled in-ear monitors, designed, built and quality checked under one roof.

Design and assembly stay in Portland

Campfire says every stage from design to shipping happens in its Portland workshop. Earphones are assembled by hand and checked before they leave. For you, that means a small-scale approach to build, with the same people responsible for each stage.

The earphone range covers several driver layouts

Campfire's lineup includes models such as the Chimera, Astrolith, Andromeda, Orion, Lyra and Jupiter, and several of them use multiple drivers in each earpiece. Check the product page for driver details, as the layout changes from model to model.

A portable DAC and amplifier sits alongside

The Relay is a portable DAC and amplifier for use between a phone or computer and a pair of earphones. Campfire describes its tuning approach as organic. That is the maker's own wording, so compare the specifications and listen to a few models if you can.

Frequently Asked Questions

Start with power (cables & distribution), then upgrade signal cabling, support (Hi-Fi Racks) and isolation accessories. These incremental changes can unlock more from your existing gear. Once you have the basic essentials, then you can look at further upgrades, such as fuses, cartridges, better isolation and more!
Loading...
It is usually best to address obvious issues first, such as unstable equipment placement or poor isolation, before adding more specialised accessories. Call (0208 905 1555) or Email (sales@futureshop.co.uk) one of our consultants to identify an ideal upgrade path for your system.
Loading...
A high-quality hi-fi system is built around a few core elements working together. At its heart is a source, such as a streamer, turntable, CD player, or digital audio player, which provides the music. This signal is then shaped and boosted by amplification, which may include an integrated amplifier, headphone amplifier, or phono stage depending on the system. The sound is delivered through speakers or headphones, which have a major influence on the overall character of what you hear. Supporting components also play an important role. DACs improve digital playback quality, cartridges and phono stages are vital for vinyl, and hi-fi racks, speaker stands, and isolation products help equipment perform consistently. A balanced system does not rely on one standout component, but on how well everything works together.
Loading...
Isolation and support products can make a clearly audible difference, especially in resolving systems. Vibrations from floors, speakers, and even airborne sound can interfere with sensitive components like turntables, DACs, and amplifiers. Proper speaker stands help speakers perform as intended by improving stability, positioning, and bass control. Hi-fi racks and isolation platforms reduce unwanted resonance, helping systems sound cleaner, more focused, and more consistent. While these products may not change the sound as dramatically as speakers or cartridges, they often unlock performance that is already there but being masked by vibration or poor placement.
Loading...
That depends on the starting point of the system. If the fundamentals are weak, such as entry-level speakers, poor setup, or missing core components, starting with the basics usually brings the biggest gains. A well-matched foundation allows later upgrades to shine. If the system is already balanced, upgrading individual components can be very effective. Improvements such as a better cartridge, DAC, phono stage, or isolation can refine detail, clarity, and realism. The most rewarding upgrades tend to be those that address the system’s weakest link rather than focusing on one category alone.
Loading...
In many systems, the biggest improvement comes from upgrading speakers or headphones, as these shape the sound more than any other component. For vinyl systems, the cartridge and phono stage are often the most influential upgrades. In digital systems, a higher-quality DAC or streamer can significantly improve clarity and timing. Beyond electronics, addressing setup, isolation, and support is often overlooked but highly effective. Improving speaker positioning, adding proper stands, or isolating sensitive equipment can deliver noticeable gains without changing core components. The best first upgrade is usually the one that removes the most obvious limitation in the current system.
Loading...
There are lots of components and tweaks that can offer a lift in performance, however, our current favourite is the UK 13A mains fuse from your wall socket to your distribution block or amplifier. This is an often overlooked component in most systems but the improvements far outweigh it's size and cost.
