Our Company

We make custom cables, The Headphone Vac, and other accessories for your in-ear monitors and earphones.

Founded in 2018 by longtime In-Ear Monitor pioneer Bogdan Belonozhko, Fir Audio exists to offer many necessary and unique accessories for all IEM owners. Fir Audio was born out of nearly a decade of experience in designing and manufacturing custom IEMs in the great Pacific Northwest.

Custom-built Cables

Our FIR Cable is a fully customizable premium IEM cable which you can order in your choice of color, connector style, and in any length you specify. Also, the Fir Cable can be customized with several different wire types. Look through the different wire types we offer to find the perfect fit for your needs, then select your custom options using the custom cable designer on our website.

IEM & Earphone Vacs

Cleaning IEMs can be tough since earwax, dirt, and other objects can get lodged deep inside the small tubing and bores of the earpiece. Instead of spending time and money shipping your ears back to the factory for a cleaning, you can get a thorough deep clean quickly with Fir Audio’s The Headphone Vac.
