NUARL / NX1Chapter2

"NX1 Chapter 2" is a wired Hi-Res earphone equipped with a single dynamic driver, marking the second release in the NX1 series.

■ Equipped with the new "NUARL DRIVER" [N10]v5X2
・By increasing the rigidity of the φ10mm carbon nanotube composite diaphragm, irregularities in frequency response at ultra-high frequencies have been improved.
It delivers high-definition sound through the combination of a voice coil made from 7N-grade OCC (Ohno Continuous Cast high-purity oxygen-free copper) and a powerful dual-neodymium magnet magnetic circuit.

■ Magnesium alloy housing
・The housing is made of magnesium alloy, a material that is lightweight yet highly rigid and produces minimal unwanted coloration. Using 5-axis CNC machining allows for a complex combination of curves—impossible with casting or forging—creating a unique design that suppresses internal resonance while ensuring a comfortable grip.

■ Uncompromising commitment to sound quality
・Incorporates "HDSS," a patented technology from T.B.I. (USA). By embedding two 3rd-generation ETL (Embedded Transmission Line) acoustic modules—one for high frequencies and one for low frequencies—it reproduces clear, three-dimensional sound across the entire frequency range. Brass is used for the nozzle material to disperse resonance points. Japanese-made, lead-free SnAgCu (tin-silver-copper) solder with 20% silver content is used for wiring and cable connections. Every unit undergoes 100 hours of burn-in to stabilize characteristics before shipping.

■ Selectable sound imaging and bass volume
・Adopts the "Interchangeable Nozzle" specification common to NUARL wired earphones. Two types of nozzles (long and short) offering two sound profiles are included, allowing users to adjust the volume of bass frequencies below 500Hz and the sense of sound imaging.

■ Cable of the same grade as high-end models
・The included cable uses the same φ0.6mm 7x7-core silver-plated copper wire found in the high-end "Overture" model. Compatible with 4.4mm balanced connections, the highly reliable straight-type plug prevents wire breakage caused by minute vibrations, making it ideal for use while carrying a music player. ■ Supports NUARL’s first 2-pin detachable cable system
・ Features the first adoption of IEM 2-pin (0.78mm) compatible connectors for the cable interface. Users can utilize a wide variety of commercially available cables.

■ Product design by Akihiro Momozaki (BATTLES DESIGN)
・ While embodying the elegance and gravitas befitting a model that delivers exceptional sound quality, the design retains the simple, neutral aesthetic characteristic of the NUARL brand.

■ Comprehensive accessory package
・ Includes two types of ear tips—"Block Ear+6n" and "Block Ear+7"—offering different lengths to balance fit and sound isolation. A convenient, round, semi-hard carrying case is also included.

■ Trade-up service
・ A trade-up service is available for existing NUARL earphone owners, allowing you to exchange your current model for the NX1 for a fee (available via the official NUARL store).

■ Peace of mind against loss
・ Supports "NUARL Care," a service that allows you to purchase a brand-new replacement unit at a reduced price if you lose one earbud, experience damage not covered by the standard warranty (e.g., drops or water submersion), or if the warranty has expired—provided you return the remaining unit.
