Campfire Audio Andromeda

The emerald-green IEM that made 'soundstage' a selling point — still adored for how it images, and now argued over on almost everything else, from its bass to whether it was ever worth $1,099.

Campfire Audio Andromeda

The short version

What to know.

The Campfire Audio Andromeda is a 2016 five-balanced-armature universal IEM — emerald-green machined aluminium, a tubeless TAEC treble chamber, $1,099 through its 2019 and 2020 revisions, now discontinued. Reviewers broadly agree on a wide, deep, out-of-head stage with precise imaging, good (if no longer class-leading) resolution, and a well-isolating sealed shell; and almost every source agrees on the trait that defines ownership — it is extremely sensitive, hisses on many outputs, and gets leaner and markedly brighter on a source with even 10 Ω of output impedance. Measured across sixteen test rigs it is close to flat from 20 Hz to 10 kHz: no Harman-style sub-bass shelf, a slight warm hump around 100–500 Hz, and roughly 9–11 dB less 2–6 kHz presence than the Harman IEM target. That tuning is where opinion splits. The larger camp hears a natural, warm-neutral, spacious sound; a sizeable minority hears it as hazy, muffled or lacking cohesion. Bass divides three ways — clean and sufficient, too light with no sub-bass slam, or a mid-bass that bleeds into the mids. Treble, dynamics, comfort around the faceted shell, a finish that chips, and value against newer, cheaper sets are all genuinely contested. The 2020 revision lifted the upper mids by about 2 dB; which version someone heard, and on what source, colours nearly every verdict.

About this product

The classic emerald-green, five-balanced-armature universal IEM: the 2016 original, its 2017–2019 refinements and the Andromeda 2020, all launched at $1,099. The 2020 revision lifts the upper mids by about 2 dB on every measurement rig that holds both; its reputed treble-spike fix is small and varies by rig. The classic Andromeda is now discontinued — Campfire sells the redesigned Andromeda Emerald Sea ($1,399) and the ten-driver Andromeda 10 instead — so it is bought used (roughly $525–$650 for a 2019, $850–$1,140 for a 2020 as of September 2026). It is distinct from the stainless Andromeda S, the seven-driver Andromeda Gold, the Emerald Sea and the Andromeda 10.

Campfire Audio's Andromeda is the machined-aluminium, five-balanced-armature in-ear that became a landmark — for years the default kilobuck IEM recommendation, iterated so often (a 2019 refinement, the Andromeda 2020, special editions in every colour) that the faceted green shell and its tubeless TAEC treble chamber are practically Campfire's logo. It launched at $1,099 in 2016 and stayed there until the classic version was retired in favour of the redesigned Emerald Sea and the ten-driver Andromeda 10.

Its reputation rests on one thing nearly everyone grants — an unusually spacious, precise stage — and on a tuning that measures far from today's norm: flat bass with no sub-bass shelf and much less upper-midrange 'ear gain' than modern Harman-style sets. Fans hear that as natural and airy; critics hear it as hazy, bass-light or incoherent. It is also notoriously fussy: it hisses on many sources, and a source's output impedance audibly re-tunes it.

A good fit for

  • Listeners who prize soundstage and imaging above all — the Andromeda's reason for being
  • People who find Harman-style IEMs shouty and want a relaxed, warm-neutral presence region
  • Owners with a clean, low-output-impedance source (or an IEMatch-type adapter) to stop the hiss and hear the intended tuning
  • Used buyers — a 2019 or 2020 at well under the old $1,099 changes the value question
  • Gamers and anyone who wants precise positional cues from an in-ear

Think twice if

  • You want sub-bass rumble and slam — the flat, all-armature bass is the most common complaint
  • You are used to Harman-tuned IEMs and like vocals forward — the relaxed upper mids can read as muffled
  • Your source has a high output impedance or audible noise — the Andromeda hisses and changes its tuning
  • You can't try the fit first — the faceted shell presses on some ears
  • You'd be paying near the old $1,099 — newer sets match its detail for less
  • You want a new, warrantied unit — the classic Andromeda is discontinued, and counterfeits circulate

The reviewer consensus

Agreement &
disagreement.

8 / 12topics divide opinion
4 Mostly agree8 Divided opinions

Common ground6

  • A wide, deep, out-of-head stage with precise imaging — the set's signature and least-argued strength.
  • Extremely sensitive and source-fussy: it hisses on many outputs, and a source with even 10 Ω of output impedance makes it leaner and several dB brighter — it wants a clean source under about 1 Ω.
  • A distinctive tuning that measures close to flat, with no sub-bass shelf and roughly 9–11 dB less upper-midrange presence than the Harman IEM target.

Points of contention8

  • Tonality: natural, warm-neutral and spacious vs hazy, muffled or incoherent — the same relaxed presence region, valued differently.
  • Bass: too light with no sub-bass slam vs clean and plenty vs a mid-bass hump that muddies the mids — a three-way split the measurements partly support on every side.
  • Mids: lush and natural (especially the 2020) vs recessed and muted behind a warm lower midrange (especially the original).

The Andromeda's signature and still its least-argued strength. Reviewer after reviewer describes a stage that is a class above most IEMs — wide, deep, layered and out-of-head — and several critics who dislike the tuning grant the stage anyway. The honest caveats are about scale and calendar rather than dissent: it is not headphone-sized, a few newer sets now match or beat it, and one owner hears the thick mid-bass crowding it.

“The width and depth afforded on the Andromeda are a class above the vast majority of other IEMs.”

Fc-Construct, Headphones.com

“the stage is startlingly open, sonic-wall free.”

Precogvision, Headphones.com

“Still probably the most spacious IEM I've heard due to its upper midrange/treble colorations.”

IEMRanking (summarising listener)

“Soundstage: I feel it's bottlenecked by the midbass.”

NickleCo, Head-Fi

Measured

The measurements explain the effect rather than contradict it: across sixteen rigs the Andromeda carries ~9–11 dB less 2–6 kHz energy than the Harman IEM target (and ~7 dB less at 2–4 kHz than a Moondrop Blessing 2 on the same rigs). Reviewers on both sides tie the stage to that relaxed ear gain — r/headphones' o0genesis0o calls it 'a reason behind its large soundstage', listener credits its 'upper midrange/treble colorations', and The Headphone Show notes that boosting an upper-mid dip shrinks perceived space. Dracomies' 2026 re-review still finds the stage wide but says newer sets now exceed it.

What to keep in mind 7

  1. This is a read of where the reviews land as of September 2026. The classic Andromeda is discontinued, so most buyers now meet it used; several value opinions are really about how much newer, cheaper sets have closed the gap since 2016.

  2. More than almost any IEM, this one depends on what you plug it into: it hisses easily, and a source with even modest output impedance makes it leaner and noticeably brighter. Impressions here assume a clean, low-impedance source — yours may sound different.
