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.
