Fir Audio Neon 4

The Neon 4 is for lovers of soft, creamy sounds. And that without compromising on resolution. The highlight of the Neon 4 is its rich, upper mids and highs. The ATOM XS module provides an excellent sense of space and positioning. The combination of these characteristics with a fast, rapid bass foundation ensures an immersive, detail-oriented listening experience.

The Custom-fit IEM is made from durable acrylic and offers a range of stylish color and design options. The universal fit version features a machined aluminum casing and beautiful sapphire crystal glass bezels.

The Neon 4 is equipped with 3 balanced armature drivers and a dynamic 10mm driver for the low frequencies, which are transmitted via the Kinetic Bass port.

Like the rest of the Frontier series, the Neon 4 is available in a universal fit and a custom fit version.
