Description

Binary Acoustics 1900 is a sophisticated hybrid in-ear monitor inspired by the cinematic artistry and musical emotion of The Legend of 1900. Each side combines a 10mm dynamic driver, 6mm passive radiator and four balanced armature drivers, integrated through a precision 3-way acoustic crossover. The dynamic driver and passive radiator work together to produce deep, energetic bass with impressive sub-bass extension, while dedicated balanced armatures deliver open mids, natural vocals and detailed, extended treble. Its lively yet balanced tuning creates an expansive presentation suitable for genres ranging from Pop and Rock to Classical, Jazz, ACG and Electronic music. Completing the experience are beautifully engraved 316L stainless steel faceplates, ergonomic resin shells and a high-purity silver-plated OFC detachable cable available in 4.4mm termination.

ADVANCED 1DD + 1PR + 4BA HYBRID ARCHITECTURE

Binary 1900 combines a 10mm dynamic driver, a 6mm passive radiator and four balanced armature drivers on each side. This sophisticated hybrid arrangement allows different acoustic components to focus on specific frequency regions, producing
powerful lows, articulate mids and refined highs with impressive separation.

FOUR BALANCED ARMATURE DRIVERS

Four balanced armature drivers complement the dynamic low-frequency system, with dedicated drivers handling the midrange and treble regions. They reproduce clear vocals, detailed instruments and smooth, extended high frequencies for a lively yet well-balanced listening experience.

PRECISION 3-WAY ACOUSTIC CROSSOVER

An innovative 3-way crossover architecture precisely distributes different frequency ranges between the dynamic, passive and balanced armature sections. Careful integration helps minimise overlap and distortion while maintaining smooth transitions and coherent performance across the frequency spectrum.



316L STAINLESS STEEL ARTISTIC FACEPLATES

Inspired by The Legend of 1900, the faceplates are crafted from premium 316L stainless steel and finished with intricate vintage-style engraving. Flowing musical notes and classic piano-inspired elements create a distinctive visual identity, while the ergonomic resin inner shells provide a secure and comfortable fit for extended
listening.

HIGH-PURITY SILVER-PLATED OFC DETACHABLE CABLE

Binary 1900 includes a high-purity silver-plated OFC braided cable designed for stable signal transmission and long-term durability. Standard 0.78mm 2-pin connectors allow easy cable replacement or upgrades, while 3.5mm single-ended and 4.4mm balanced termination options let users choose the connection that best suits their audio setup.
