Limited Edition 5th Year Anniversary Model

Fir Audio's Radon 6 is a 5 Year Anniversary model limited to 300 units world-wide. Celebrating five years in pursuit of the ultimate in-ear monitor listening experience. Based on Fir Audio's popular Xenon 6, retuned with a leaner, lighter sound signature.

Featuring an all-new satin black aluminum shell, gorgeous sapphire crystal glass faceplates, an exclusive cable, and a tribrid driver system.

The tribrid system consists of tubeless balanced armature OpenDrivers, an ultra-high electrostatic tweeter, and a dynamic driver with the revolution- ary Kinetic Bass technology - all working in perfect harmony.

The Radon 6 is a new addition to the Frontier Series with Kinetic Bass, Open Acoustics, ATOM Venting, and Rigid Technologies.

Kinetic Bass

Featuring a 10mm dynamic driver, open and facing the outside of the IEM shell. Allowing low frequencies to be transmitted directly to the ear cartilage. Resulting in a bass you can feel with increased dimension and an off-the-charts low frequency extension.

Open Acoustics System

The Open Acoustics technology consists of three major parts: Open Drivers, Sound Reactor, and Sound Reflector. Enabling smooth, airy highs with great high frequency extension, and allows pure and natural sound to flow freely into the ear canal.

Atom XS Venting

Venting harmful air pressures from inside a sealed ear canal. Your eardrums stay relaxed and you can listen to music longer without ear fatigue. The sound-stage is also wider and feels more natural.
