Audeze LCD-5s - Open Back Planar Magnetic Headphones with SLAM Technology

he Audeze LCD-5s is the jewel of Audeze's audiophile line-up, taking their flagship open-back planar design to a top tier sonic experience. Engineered as the definitive mastering-grade reference tool for top-tier audio professionals and critical listeners, the LCD-5s expands upon legendary transparency by introducing a richer midrange, musical warmth, and an incredible low end. Hand-assembled in California using premium carbon fibre, magnesium, genuine leather, and polished polymer acetate, the LCD-5s delivers a natural sense of scale and presence without fatigue. The defining hallmark of the LCD-5s is its patent-pending Symmetric Linear Acoustic Modulator (SLAM™). While planar diaphragms are renowned for speed, they can occasionally lack visceral, physical low-end punch. SLAM™ solves this by implementing precisely engineered acoustic channels that optimise internal airflow and pressure distribution. At the heart of the housing sits an advanced Neodymium N50 planar driver incorporating a Parallel Uniforce™ diaphragm constructed from Audeze's thinnest, most responsive nano-scale film. The driver produces flawless high-resolution reproduction and effortless high-frequency extension with almost no distortion The LCD-5s relies on a lightweight magnesium and carbon fibre frame to provide structural rigidity and lightness. This includes newly sculpted, internally sloped earpads providing a seamless acoustic seal against your head while minimising internal reflections to ensure pinpoint stereo imaging. Key Features Symmetric Linear Acoustic Modulator (SLAM™): Delivers a tactile, bass enhancement and punch without clouding the mid-range. Parallel Uniforce™ Nano-Scale Diaphragms: Near-weightless film ensures instantaneous transients and microscopic detail. Lightweight Magnesium & Carbon Fiber Build: Premium materials keep the overall frame lightweight ideal for long tracking and mastering sessions. Sculpted Earpad Geometry: Internally sloped cushions maximise comfort, pressure distribution, and acoustic isolation. Ultra-Pure Directional OCC Copper Cable: Supplied with an upgraded, low-capacitance premium balanced 4-pin XLR cable (adapter included).
