Power & Performance

• Transducer Type: Planar Magnetic
• Transducer Size: 106 mm
• Frequency Response: 10Hz – 50kHz
• Sensitivity: 105 dB/1mW (at Drum Reference Point)
• Impedance: 20 Ohms
• Maximum SPL: >130dB
• Total Harmonic Distortion (THD): <0.1% @ 100dB SPL, 1kHz
• Power Handling: 5W RMS (Maximum)
• Recommended Power: >250mW (Minimum requirement >100mW)
• Performance: The Audeze LCD-MX4 represents a powerful fusion of Audeze’s Flagship and Reference lines. By combining the easy-to-drive diaphragm of the LCD-X with the extreme magnetic force of the flagship LCD-4, the MX4 is a high-efficiency beast. It is specifically designed for audio engineers who need flagship-level detail and "microscopic" clarity but may find themselves working on a laptop, a mixing console, or in a studio without a high-powered external headphone amplifier.

Audio Features & Drivers

• 1.5 Tesla Magnetic Flux: Features a massive Double Fluxor™ Magnetic Array that achieves a staggering 1.5 Tesla of magnetic flux—the most powerful magnetic circuit in its class. This immense force provides the driver with absolute control, resulting in lightning-fast transients and authoritative, precise bass response.
• Ultra-Thin Uniforce™ Diaphragm: Utilizes an ultra-lightweight, NASA-grade diaphragm with variable-width voice coil traces. This ensures the 106mm driver moves with uniform force across its entire surface, virtually eliminating distortion and providing lifelike imaging.
• Fazor™ Phase Management: Equipped with patented Fazor waveguides that act as acoustic lenses, guiding sound waves to prevent interference. This technology is critical to the MX4’s "room-like" bloom and expanded soundstage, helping engineers accurately position elements in a 3D mix.
• Professional Studio Tuning: The MX4 is engineered for maximum translatability. Its neutral frequency response ensures that "sparkle" in vocals or "cut" in percussion is represented honestly, so your final mix sounds consistent across all playback devices.
• Unrivaled Efficiency: At 105dB sensitivity and 20 ohms, the MX4 is the most efficient full-sized LCD model. It is a "plug-and-play" reference tool that delivers consistent, high-fidelity performance across a vast range of professional and portable gear.

Streaming & Connectivity

• Dual 4-Pin Mini-XLR Inputs: Features gold-plated, locking mini-XLR connectors on the earcups. These professional-grade jacks ensure a secure, low-resistance connection and allow for easy switching between different cable types.
• Premium OCC Copper Cable: Includes a 1.9m (6.2ft) high-purity, 20 AWG audio-grade OCC copper braided cable. The cable is single-ended and terminated with a professional 1/4" (6.3mm) TRS plug.
• Universal Adapter: Comes with a high-quality 6.3mm to 3.5mm adapter cable, facilitating a direct connection to laptops, mobile interfaces, or portable digital audio players (DAPs).
• Reveal+ Compatible: Fully optimized for Audeze’s Reveal+ software, allowing engineers to apply AI-generated hearing maps and room emulations to simulate world-class studio monitors through the headphones.
• Pure Analog signal: A strictly passive device with zero digital processing or internal batteries, ensuring the shortest, cleanest signal path possible for critical monitoring.

Comfort & Dimensions

• Lightweight Magnesium Housing: Built on a rugged but lightweight magnesium chassis. This material choice makes the MX4 significantly lighter than the LCD-4, specifically designed to reduce neck strain during 12-hour mixing marathons.
• Carbon Fiber Suspension Headband: Features a genuine carbon fiber headband paired with a perforated leather suspension strap. This combination provides excellent support while effectively distributing weight across the head.
• Premium Leather Earpads: Outfitted with Audeze’s thickest, contoured memory foam earpads wrapped in premium leather (Leather-Free options often available). These pads are designed to breathe and maintain a consistent seal for optimal bass response.
• Unit Weight: 575g (1.27 lbs) — roughly 30% lighter than the flagship LCD-4.
• Acoustic Seal & Fit: The cast magnesium yokes provide a wide range of movement, ensuring the headphones stay comfortable and securely sealed even when you're moving around the mix desk.

Design & Build

• Industrial Professional Aesthetic: Dressed in a sleek, matte-black "stealth" finish that emphasizes its role as a high-precision tool for the modern production environment.
• Engineered for Longevity: Constructed using high-strength magnesium and spring steel, the MX4 is built to survive the rigors of travel and constant professional use.
• Hand-Assembled in USA: Every pair is precision-crafted and frequency-matched by hand in Audeze’s Southern California facility to ensure it meets the exacting standards of the world’s top engineers.
• Professional Travel Case: Includes a heavy-duty, waterproof, and crush-proof travel hard case with a custom-fit foam interior to protect the headphones and accessories on the road.
• Feedback-Driven Design: The MX4’s physical architecture was refined based on direct feedback from professional engineers, resulting in a headphone that balances flagship performance with practical, everyday usability.

For most products, we cover three years for the drivers and one year for the rest of the parts, and this begins from the original date of retail purchase. Warranty on Mobius (discontinued), Penrose (discontinued), Maxwell, MM-100, LCD-S20 and FILTER is one year for all parts including drivers, except in the EU and UK, where minimum warranty may be longer, or anywhere else as mandated by local laws.

 For the full text of our warranty policy, please download and view this PDF.

 Warranty coverage is limited to factory defects only, not wear and tear or cosmetic damage from use. Please note that we consider earpads, headband straps/cushions, eartips, earlocks, earhooks, and batteries to be "consumable items" and offer no warranty on those parts.

 As long as product was originally purchased from an authorized dealer, the warranty is transferable and is valid from the original date of purchase. We just ask for proof of that purchase date by using the original purchase receipt. If no original receipt is available, we use the date of manufacture or shipment from our facility for the beginning of the warranty period, and warranty coverage is discretionary.

 We reserve the right to deny warranty claims for purchases originally made from anyone NOT on the dealer list, and proof of original purchase is required to claim warranty service.

 Warranty Service Guidelines:

For direct warranty service we cover parts, labor and return shipping to the customer, so the only cost to customers is shipping the product to us for repair. If a defect occurs within the first 30 days after the original retail sale, we pay for shipping both ways from the original point of delivery by providing a pre-paid shipping label. The decision to repair or replace a defective product is solely at Audeze's discretion.

Products must be serviced either by the distributor we sold them to, or directly by us here in the USA. If a product was purchased in the USA, it must be returned for service here, not to any international distributor. Likewise, a product purchased in any specific country must be returned for service to that country (or directly to us in the USA). For this reason we recommend that international customers purchase locally when possible, so any service needs can also be handled locally by our dealers or distributors. We also recommend verifying service contracts with dealers/distributors before purchase, as they are independent businesses and have their own policies in place.
