Campfire Audio Alien Brain Hybrid In-Ear Monitor

A five-driver system with one dynamic driver and four BA's. Campfire's portable DAC included

Alien Brain is Campfire's latest in its long legacy of premium hybrid-design IEMs with a new five-driver internal architecture. Drawing from over a decade of engineering, experimentation, and innovation, Alien Brain offers a new iteration of its Dual Magnet Dynamic Driver for bass, and four balanced armatures, two for the mids, and two for the highs. 

Dynamic drivers offer greater weight and scale, and balanced armatures are renowned for their speed and detail. With Campfire's careful treatment and tuning, these drivers coalesce to form a smooth, musical, and engaging listen.

New Dual-Magnet DD

First introduced in Bonneville and Cascara, the Dual Magnet DD quickly became a fan-favorite. This latest iteration features an exciting new glass-pu diaphragm; with a glass speaker dome and polyurethane coating.

Experience incredible bass texture and impact, without being overbearing. Giving you just the right amount of low-end power to infuse energy into your tracks without crowding out the rest of the frequency spectrum.

Premium Cranium

Alien Brain's precious cerebrum is firmly protected in a black PVD stainless steel shell made from full billet CNC capped off by Campfire's new, transparent, iridescent, lightweight dome lid, revealing the inner-workings of each cranium.

Alien Brain was fully designed, engineered, assembled, tested, QC'd, packed, and shipped by Campfire's small team of professionals from its singular location in the heart of Southeast Portland, Oregon.

Phase Harmony Engineering

Campfire Audio emphasizes quality over quantity. In the arms race to fit a higher and higher number of drivers into an earphone, the Portland company finds that a results-driven technique to driver treatment produces superior results with less room for pitfalls and ever-expanding variables that can undermine product consistency. 

One of the products of this approach is Phase Harmony Engineering, that allows Campfire to segment the frequency spectrum and assign these segments to specific drivers, and allows those drivers to apply their strengths to that area. Using a combination of precision-engineered driver housings and shell geometry, coupled with custom damping values the team is able to physically shape the tuning and response of the drivers, and further, their interaction with one another. This driver-to-driver interaction is crucial to eliminating points of potential phase cancellation and creating the intangibles that don’t show on a frequency response curve; imaging, separation, resolution, and soundstage.
