Bring cinematic depth and audiophile precision to your listening setup with the Binary Acoustics 1900. Inspired by the classic film The Legend of 1900, this hybrid in-ear monitor combines a 10mm liquid-silicone dynamic driver, a 6mm passive radiator, four customized balanced armature drivers, a triple-tube physical crossover, and vintage piano-engraved 316L stainless steel faceplates.

Key Features

* Six-Driver Hybrid Acoustic Architecture
Combines one 10mm dynamic driver, one 6mm passive radiator, and four balanced armature drivers per side, dividing frequencies across bass, midrange, and treble for low distortion and wide dynamic range.

* Dual Dynamic Bass Engine with Passive Radiator
A 10mm liquid-silicone surround dynamic driver works in tandem with a 6mm passive radiator to move air efficiently inside the acoustic chamber, delivering textured sub-bass rumble without bleeding into the lower midrange.

* Dedicated Four Balanced Armature Midrange and Treble Array
Features two dedicated BA drivers for clear, uncolored vocal performance alongside two high-frequency BA drivers that deliver smooth treble extension and micro-detail retrieval without sibilance.

* Physical Triple-Tube Three-Way Crossover
Uses independent physical acoustic sound tubes paired with an electronic crossover network to isolate frequency bands, ensuring phase coherence and precise instrument separation across an expansive soundstage.

* Vintage Piano Engraved 316L Stainless Steel Faceplates
Crafted with CNC-machined 316L stainless steel faceplates featuring vintage piano key artwork, paired with ergonomically contoured 3D-printed resin inner shells for a comfortable, fatigue-free fit.

* High-Purity Silver-Plated OFC Braided Cable
Includes a detachable high-purity silver-plated oxygen-free copper cable with flush 0.78mm 2-pin connectors, available in 3.5mm single-ended or 4.4mm balanced termination options.
