Look & Feel
The Campfire Audio Grand Luna reminds me of the Astrolith in design. Its faceplate is stainless steel, but with more of a refined look. The underside of the Grand Luna features a transparent shell that is internally dyed. They look more like two separate pieces placed on top of each other rather than one whole piece, but I don’t think this takes anything away from the Grand Luna having a premium look. In terms of fit, the Grand Luna is light and fairly ergonomic. They sit in my ears without much of a fight, resulting in multiple hours of listening time without fatigue.
Design
This is Campfire Audio’s first hybrid design, blending a cutting-edge 14 mm planar-magnetic driver (handling the low to mid-range frequencies) with two high-frequency balanced-armature drivers to deliver extended clarity up to 30 kHz. A standout feature is the new swappable cable system, allowing users to switch between 3.5 mm single-ended, 4.4 mm balanced, or a USB-C DAC termination (featuring a Cirrus Logic CS43131 DAC), enhancing connectivity and convenience across devices.
Soundstage
While Campfire Audio’s IEMs usually feature large soundstages and solid imaging, the Grand Luna is the best I’ve heard in a while. Campfire’s past IEMs have had airy and holographic soundstages that provided great immersion, but the Grand Luna does more than that. It presents a highly dimensional stereo field that is also locked into specific positions, making them easy to localize. The Grand Luna shows more accuracy here than what I’ve heard from previous Campfire IEMs in the past. Layers of sound are articulately displayed, folding over and under each other with high separation value. What makes the Grand Luna unique among other Campfire IEMs is its ability to simulate a live environment exceptionally well. Everything feels propelled forward, with realistic panning movement and depth. It extends wide and features natural scale in a way that makes each sound appear full in the mix.
Low End
The bass on the Grand Luna has a particular flavor to it that I can see a lot of people enjoying. I think the Grand Luna leans a little too dark for me to be fully engrossed by it. I certainly like the presence and tonality that the Grand Luna offers, but the quality of notes is a bit lacking for me. While there’s movement and groove to it, there’s something about it that comes off as dry to me. It’s a smooth timbre that thumps and bounces around well enough, but it never reaches a resolving response in my opinion.
Mids
Midrange frequencies show natural extension through the Grand Luna. Instruments are smooth like the bass, but have a tad more detail to them, featuring slightly more transparency and weight. There’s nothing vibrant or exciting about the way instruments resolve in the midrange, but their level of fullness and clear shape are gripping enough to be engaged by. Instruments and vocals sit on the same level, balancing next to each other, which showcases roominess but also results in a flatter tone.
Highs
These are not the most favorable IEMs for treble clarity. There’s a steep roll-off that deadens a lot of the frequency response. While this makes the highs very easy to listen to, it doesn’t leave you with any details to get excited about. The treble is mostly quiet and reserved, leaving cymbals and bells sounding a bit dull.
Summary
The Campfire Audio Grand Luna is an ambitious IEM that pushes the brand into new territory. Its expansive soundstage, ergonomic build, and innovative cable system make it a compelling choice for listeners who want versatility and a natural sense of space in their music. While its darker tonality and rolled-off highs may not appeal to those seeking ultra-bright detail, the Grand Luna excels in presenting music with scale, immersion, and a refined character. For fans of Campfire Audio, or anyone looking to experience a unique blend of planar power and balanced-armature clarity, the Grand Luna stands as a distinctive addition to the company’s lineup and a celebration of its decade-long pursuit of sonic artistry.
