Audeze LCD-S20 Closed Back Headphone

Studio-Grade Sound. Isolation That Matters.

The LCD-S20 brings Audeze’s professional planar magnetic engineering into a closed-back format designed for serious use in studios, tracking sessions and focused listening. With 90 mm planar drivers, SLAM™ (Symmetric Linear Acoustic Modulator) technology for extended, clean bass, and passive isolation that minimizes microphone bleed and external noise, the LCD-S20 delivers detail, depth and control in environments where precision is key.

Deep, controlled bass with clarity

Featuring Audeze’s SLAM™ technology built into the closed-back design, the LCD-S20 offers bass that hits with authority yet stays tight and defined — even at high volumes. The included 90 mm planar drivers and low distortion tuning ensure you hear nuanced sub-harmonics, rhythmic clarity and impactful dynamics.

Professional-grade engineering

Built with Uniforce™ ultra-thin diaphragms, Fluxor™ magnet arrays and Fazor™ waveguides, the LCD-S20 inherits the advanced technologies found in Audeze’s flagship models. The closed enclosure is acoustically dampened to prevent bleed, meaning it’s ideal for studio tracking, vocal isolation or any situation where ambient sound must stay out.

Designed for real world studio comfort

Constructed from magnesium, aluminum and steel, the LCD-S20 is built to last. It features magnetically-attached earpads (convenient for maintenance and customization), a suspension headband for balanced weight distribution, and a substantial cable connection system suitable for pro rigs.

Closed-back design with professional purpose

Unlike many open-back planars, the LCD-S20 uses its closed structure to block out environmental distractions and prevent sound leakage — making it perfect for vocal booths, tracking rooms, editing bays and even immersive listening without compromise.

What’s Included

• LCD-S20 closed-back planar magnetic headphones

• 2.5 m (≈ 8.2 ft) high-quality headphone cable

• 3.5 mm to 6.3 mm adapter

• Quick start guide and warranty documentation

Comfort Notes

With a weight of approximately 550 g and a professional build, the LCD-S20 is robust but designed to remain comfortable during long sessions. The suspension headband and gel-filled earpads help mitigate fatigue, and the magnetically-attached earpads allow easy maintenance or future replacements.

Versatility Notes

While the 18 Ω impedance and 93 dB/mW sensitivity make the LCD-S20 relatively efficient for a planar, we recommend using a high-quality headphone interface or amplifier to fully unlock their dynamic performance, especially in tracking/studio use. The closed-back format also means you can monitor in shared spaces without risk of bleed or outside interference.
