Brand new and factory sealed — the FiR Audio Neon 4 Universal In-Ear Monitor is a standout hybrid IEM from the acclaimed Frontier Series. Purchased as extra gear by a band that never put them to use — still sealed and untouched.
The Neon 4 is built for the lover of smooth, creamy sound without sacrificing resolution. Lush upper mids and trebles, a stellar sense of space and positioning from the ATOM XS module, and a snappy, tactile bass foundation make for an immersive, detail-oriented listen. Machined aluminum shells, sapphire crystal glass faceplates, 3 balanced armature drivers and a 10mm dynamic driver for lows, all fed through FiR Audio's Kinetic Bass port. Part of the Frontier Series, available in Universal-Fit and Custom-Fit models.
Kinetic Bass — A hybrid conduction technology that takes the IEM sound experience to a whole new level. Bass you can hear and physically feel.
Open Acoustics System — Open drivers with no sound tubes that radiate sound directly into the Sound Reactor for a much larger, more natural soundstage.
ATOM XS Venting — A pressure relief system that vents harmful air pressure from inside a sealed ear canal — greatly reducing listener fatigue so you can hear more and listen longer.
