Fir Audio Radon 6 Custom In Ear Monitor

Please contact our team for configuration and personalisation options.

The Custom-fit model is limited to 100 units world-wide and only 20 units produced per month. Celebrating 5 years in pursuit of the ultimate in-ear monitor listening experience.

We’ve applied everything we learned from Frontier Series and mindfully retuned our popular 6-driver model and arrived at a leaner, reference warm sound signature. Featuring proprietary technologies such as Kinetic Bass, ATOM Venting, Open Acoustics, and Rigid Technologies.

The Custom-Fit model features all of the premium design options of the Frontier Series. The Rn6 CIEM also ships with the exclusive pure silver cable with copper shielding.

KINETIC BASS

A hybrid conduction technology that takes the IEM sound experience to a whole new level. Kinetic Bass is a bass you can feel. Learn More

ATOM VENTING

A pressure relief system that vents pressures that build up in a sealed ear canal. Greatly reducing listener fatigue so you can hear more and listen longer. Learn More

OPEN ACOUSTICS 

Open drivers with no sound tubes that radiate sound directly into the Sound Reactor which results in a much larger sound stage. Learn More

RIGID TECHNOLOGIES 

Proprietary technologies that provide industry leading durability and serviceability of our in-ear monitor products. Learn More
