FIR Audio E12 Universal In-Ear Monitor Front View

Introducing the Electron 12 (e12), a revolutionary leap in the world of In-Ear Monitors (IEMs) that defies all expectations. Our groundbreaking SwapX technology sets it apart, allowing you to switch up the look of your IEM with ease using user-replaceable faceplate designs. Customize your Universal-fit experience with our premium designs and materials for a truly personalized touch.

Beneath the sleek exterior, the e12 boasts a powerful single electro-dynamic 12mm driver featuring our Tactile Bass Technology. Crafted with precision from top-tier materials, the driver undergoes rigorous testing to meet our uncompromising standards for sound quality. With a single source of sound, the e12 achieves unparalleled phase coherence, delivering an immersive listening experience that spans from airy, crispy highs to the profound depths of the lows.

Our proprietary Tactile Bass Technology utilizes the entire solid shell, allowing bass to reverberate through, creating a textured and tactile feel to the low end. The machined aluminum shell, with its solid insert facilitates the Tactile Bass technology, and also ensures durability and a premium aesthetic.

The modular design of the shell, with a main faceplate attached by screws, enhances efficiency and serviceability, ensuring your investment stands the test of time.

Adding to the e12’s arsenal is the exclusive ATOM Venting system, widening the soundstage and providing a natural listening experience that’s second to none. And to top it off, we’ve included a stunning 8-braid, pure silver oxygen-free cable with copper shielding in a clear jacket, completing the package with both style and sophistication. Elevate your audio experience with the e12—where innovation meets premium craftsmanship.


A revolutionary technology that incorporates user-replaceable faceplate designs,
removable faceplate assembly which provides easy access to the internal components
and a removable 2-PIN connector for more efficient repairs and servicing.

Tactile Bass

The 12mm electro-dynamic driver is uniquely coupled with the IEM chassis to act as a
secondary transducer for lower frequencies. This results in a deeper and richer bass,
providing a more engaging listening experience.

ATOM Venting

Venting harmful air pressures from inside a sealed ear canal. Your ear drums remain
relaxed, allowing you to listen to music longer without ear fatigue. The soundstage also
widens and sounds more natural.
