The Audeze LCD-5s: A New Horizon in Planar Performance

The Audeze LCD-5s redefines flagship planar magnetic performance by perfectly balancing clinical accuracy with deep, physical impact. At its core is the innovative SLAM™ (Symmetric Linear Acoustic Modulator) system, which manages internal airflow to unlock a commanding bass response and a highly dimensional, holographic soundstage. The result is a sonic presentation that shifts from merely detailed to deeply involving, offering an authentic sense of physical space and realistic scale.

On a technical level, the LCD-5s features a 90mm Nano-Scale Parallel Uniforce™ diaphragm with a 30-ohm impedance, making it an ideal match for premium amplification. This overhauled driver system is voiced specifically for an organic midrange and pristine high-frequency detail. Boasting a vast 5Hz–50kHz frequency range and ultra-low distortion ($\le 0.1\%$), it functions as a dependable, mastering-grade reference for industry professionals and audiophiles alike.

Weighing in at 475g, the lightweight frame utilizes a mix of magnesium and carbon fiber, beautifully accented by copper hardware and tortoiseshell acetate. Redesigned, contoured earpads elevate comfort by balancing clamping force and reducing acoustic reflections inside the cup for fatigue-free listening. Crafted by hand in California, each unit ships with a high-purity OCC copper cable and a rugged aluminum travel case, cementing its status as a premier luxury headphone.

Key Features & Technologies

SLAM™ Acoustic Modulation

The breakthrough element of the LCD-5s is the Symmetric Linear Acoustic Modulator (SLAM™). By precisely regulating internal air pressure, this technology grants the diaphragm greater physical excursion and control. The optimized airflow generates a tactile, punchy low-end and a spacious, three-dimensional stage, elevating the presentation into a vivid, lifelike listening experience.

Nano-Scale Diaphragm Precision

The headphone's performance centers around a 90mm Nano-Scale Parallel Uniforce™ diaphragm. The exceptionally thin material reacts instantly to micro-dynamics and subtle musical nuances. By employing variable-width voice coil traces, Audeze achieves uniform current distribution across the entire surface, delivering a linear frequency response virtually free of conventional distortion.

Professional-Grade Tuning

The acoustic profile of the LCD-5s is engineered for a highly accurate midrange and smooth, extended highs. Its 30-ohm impedance presents an easy, stable load for high-end headphone amplifiers. This meticulous voicing makes it a trustworthy monitoring tool, giving audio engineers the precision required to make definitive mixing and mastering choices.

Lightweight Magnesium Chassis

To achieve both structural integrity and weight reduction, Audeze crafted the frame from carbon fiber and magnesium. This high-end construction provides a acoustically inert, resonance-free housing for the drivers while keeping total weight to 475g. It delivers a rugged, studio-ready build without the physical strain often caused by bulkier planar designs.

Contoured Ergonomic Comfort

Engineered for marathon sessions, the LCD-5s incorporates newly sculpted, angled earpads. These pads are tailored to distribute pressure evenly across diverse head shapes. In addition to improving the fit, the specialized internal geometry prevents acoustic reflections, keeping the audio signal pure and the stereo imaging exceptionally sharp.

Flagship Craftsmanship

Each LCD-5s is meticulously hand-built in California, utilizing premium materials like high-gloss tortoiseshell acetate and striking copper hardware. The premium presentation is completed by an included high-purity OCC copper cable and a durable aluminum protective case—ensuring these headphones are a long-term investment in world-class audio.
