Fir Audio

What Fir Audio does

Fir Audio is a privately-held US-based designer and manufacturer of custom and universal in-ear monitors (IEMs), serving professional musicians, touring artists, and live performers globally. The company offers a portfolio spanning six custom IEM models (Electron 10/12, Ne4, Kr5, Rn6, Xe6) built from customer-submitted ear impressions using medical-grade hypo-allergenic acrylic, plus a flagship universal IEM (Project K, priced at $2,799) featuring titanium shells, sapphire glass top, and proprietary multi-driver configurations.

The company's technology stack centers on proprietary audio innovations including ATOM (Air Transferring Open Module), a pressure-relief venting system that reduces listener fatigue in sealed ear canals; OpenDriver balanced armature drivers for mid and high-frequency reproduction; and a 9mm Kinetic Bass Dynamic Driver for low-frequency response. Custom orders follow a 6-8 week standard build with optional rush processing ($499 for 7-day or $649 for 4-day), creating a workflow that requires audiologist-mediated ear impressions and direct factory-to-customer logistics.

Fir Audio operates a hybrid go-to-market model combining direct-to-consumer e-commerce (firaudio.com with an IEM Designer tool) and a global authorized dealer network spanning 20+ countries across North America, Europe, Asia-Pacific, the Middle East, and Oceania. Manufacturing is conducted through a wholly-owned subsidiary, Dongguan FIR Audio Electronics Co., Ltd., in Guangdong, China, while the US entity (Fir Audio LLC, Washington) maintains headquarters in Vancouver, WA and additional offices in Nashville, TN and Los Angeles, CA. Ancillary revenue streams include CIEM remolding services ($500-$900), refit/repair, and accessories such as ATOM venting modules and replacement cables.
