FIR Audio Neon 4 Universal In-Ear Monitor
Neon 4
The Neon 4 is for the lover of smooth, creamy sounds. Which it achieves without sacrificing resolution. The Neon 4’s highlight lies in its lush, upper mids and trebles. As well as a stellar sense of space and positioning from its ATOM XS module. Place these characteristics on a snappy, speedy bass foundation for an immersive, detail-oriented listen.
The Neon 4 features a machined aluminum shell, a sapphire glass faceplate, equipped with 3 balanced armature drivers, a 10mm dynamic driver for lows, fed into FiR Audio’s Kinetic Bass port.
Along with the rest of the Frontier Series, the Neon 4 comes in Universal-Fit and Custom-Fit models.
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.
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.
OPEN ACOUSTICS
Open drivers with no sound tubes that radiate sound directly into the Sound Reactor which results in a much larger sound stage.
RIGID TECHNOLOGIES
Proprietary technologies that provide industry leading durability and serviceability of our in-ear monitor products.
