Every Campfire Audio IEM is designed and assembled by hand in Portland, Oregon. The same workshop, the same small team, and the same production process that Ken Ball started with in 2015. This is what that looks like and why it matters to the sound.

Andromeda has been in continuous production for close to a decade. In a market where most products are replaced within two or three years, that kind of longevity is rare. This is the story of how Andromeda began, what has changed across its iterations, and what Andromeda Emerald Sea and Andromeda 10 represent today.

Campfire Audio has been building IEMs by hand in Portland, Oregon since 2015. Ten years is not a number this industry hands out easily. Products come and go. Brands pivot. The small team in Portland kept building the same way, in the same place, with the same commitment. This is what that looks like from the inside.

The IEMs we build in Portland are used by professional musicians on stage and in the studio. Some of those musicians have worked directly with us during development, shaping the final product through professional use. Alessandro Cortini of Nine Inch Nails is one of them. This is how those partnerships work and what they produce.

Getting the most from an in-ear monitor requires more than the IEM itself. A complete musician's IEM rig involves a source, a signal path, a monitor mix, and an IEM matched to how and where you perform. This guide covers the full setup for live performance and studio use, and routes to the right Campfire Audio IEM for each context. For the case for switching from floor wedges to IEMs, see our stage monitoring guide for live performers.

In-ear monitors changed how musicians hear themselves on stage. A clean mix delivered directly to the ear canal, complete passive isolation, and zero feedback risk. We build IEMs designed for this environment: Bonneville, Ponderosa, and Clara, all hand-built in Portland, Oregon, and tuned for professional performance demands.

The source device powering your IEM shapes what you actually hear. Most IEMs perform adequately from a smartphone. High-performance multi-driver IEMs at the mid-tier and above respond to a quality DAC and amplifier in ways that are genuinely audible. This guide explains what a DAC and amplifier do, when the upgrade is worth it, and how to match your source to your IEM.

The cable connecting your IEM to a source device is not simply a wire. It is the signal path, and understanding it makes a real practical difference when choosing a source device, replacing a cable, or deciding whether an upgrade is worth considering. This guide covers the two connector standards, the main termination options, and what cable changes actually do.

IEM drivers come in four primary configurations: dynamic drivers, balanced armatures, planar magnetic drivers, and hybrid designs combining two or more types. Campfire Audio also integrates advanced technologies including bone conduction systems and electrostatic super-tweeters in flagship models. Each driver type produces a distinct sound character. Campfire Audio designs and builds IEMs across all configurations at its Portland, Oregon workshop, applying custom driver implementations and proprietary acoustic treatments at each tier.
