Audeze LCD-MX4 Professional Reference Planar Magnetic Headphones

The Audeze LCD-MX4 is built for people who need to hear everything.

Designed for professional mixing, mastering and critical listening, the LCD-MX4 combines the proven accuracy of Audeze's LCD-X platform with technology derived from its flagship headphones.

The result is an exceptionally revealing open-back planar magnetic headphone with powerful, controlled bass, extremely low distortion and enough efficiency to work directly from many professional interfaces, consoles and recording devices.

For the studio, it's a serious reference tool.

For home listening, it's an incredibly transparent window into the recording.

106mm Planar Magnetic Drivers

The LCD-MX4 uses Audeze's massive 106mm planar magnetic transducers.

The large diaphragm provides considerably more radiating surface than a conventional dynamic headphone driver, while its extremely low moving mass allows it to react quickly to changes in the musical signal.

That combination gives the LCD-MX4 the speed, low-frequency control and resolution required for critical professional work.

Double Fluxor Magnetic Array

One of the defining technologies of the LCD-MX4 is Audeze's patented Double Fluxor magnetic array.

The magnetic structure produces a flux density of:

1.5 Tesla

Audeze describes it as the most powerful magnetic circuit used in a headphone.

That tremendous magnetic force gives the MX4 precise control over its planar diaphragm, contributing to exceptional transient response, detail retrieval and low-frequency accuracy.

Ultra-Thin Uniforce Diaphragm

The LCD-MX4 pairs its Double Fluxor array with Audeze's patented Ultra-Thin Uniforce diaphragm.

The Uniforce voice-coil design distributes force more uniformly across the diaphragm, helping reduce distortion and allowing the driver to respond accurately even to very small changes in the signal.

That makes subtle EQ changes, compression, reverb tails, low-level details and spatial information easier to hear.

For a mixing or mastering engineer, that's exactly the point.

Fazor Phase Management

Audeze's Fazor waveguides help manage the acoustic energy traveling through the magnetic structure.

The Fazor elements reduce interference and improve phase behavior as sound leaves the diaphragm.

The result is more precise imaging, better separation and a more convincing sense of where individual elements sit within a mix.

Accurate, Controlled Bass

Bass is one of the LCD-MX4's biggest strengths.

The combination of the huge planar diaphragm and powerful Double Fluxor magnet array gives it exceptional control at low frequencies.

Instead of simply producing a lot of bass, the MX4 lets you hear what's actually happening down there.

Bass lines remain defined. Kick drums have impact without becoming bloated. Multiple low-frequency elements are easier to separate from one another.

For professionals working on low-end balance, that matters.

For audiophiles, it makes music sound incredibly authoritative.

Take the Room Out of the Equation

A great monitoring room is expensive.

Acoustic treatment, speaker placement, bass management and room correction all matter when you're trying to make reliable mix decisions.

The LCD-MX4 removes much of that variable.

Its controlled bass, low distortion and highly resolving planar drivers allow engineers to work consistently without relying entirely on the acoustics of the room around them.

That makes the MX4 particularly useful for remote work, mobile production and studios where the monitoring environment isn't always perfect.

Open-Back Spatial Presentation

The LCD-MX4 is a fully open-back headphone.

The open architecture allows the planar drivers to interact freely with the surrounding air, contributing to a spacious presentation that helps the listener identify placement, depth and separation within a recording.

Audeze specifically designed the MX4 to provide a more room-like sense of space rather than collapsing everything directly between the ears.

Audeze's Most Sensitive LCD Headphone

One of the most useful things about the LCD-MX4 is how easy it is to drive.

Nominal impedance is:

20 ohms

Sensitivity is:

105dB / 1mW

That makes the MX4 Audeze's most sensitive LCD-series headphone.

Minimum power requirement is greater than:

100mW

with Audeze recommending more than:

250mW

The MX4 can therefore work directly with many audio interfaces, consoles and recording devices without requiring a large dedicated headphone amplifier.

But better electronics still matter.

Pair it with a high-quality DAC and headphone amplifier and the MX4 has enough resolution to show you exactly what those components are doing.

10Hz–50kHz Frequency Response

The LCD-MX4 has a specified frequency response of:

10Hz–50kHz

Maximum output exceeds:

130dB SPL

Total harmonic distortion is rated at:

Less than 0.1% at 100dB

Maximum power handling is:

5 watts RMS

Those specifications give the MX4 substantial dynamic capability while maintaining the low distortion necessary for professional monitoring.

Magnesium and Carbon Fiber Construction

The LCD-MX4 uses a lightweight magnesium chassis rather than the heavier construction found on some other LCD-series headphones.

A carbon fiber suspension headband distributes weight across the head, while premium ear pads provide support during longer sessions.

The finished headphone weighs:

575 grams

That's still a substantial reference headphone, but the material choices make it better suited to the long mixing, mastering and listening sessions it was designed for.

Built for Professional Work

The LCD-MX4 isn't simply an audiophile headphone that happens to work in a studio.

Professional use is central to its design.

Its neutral tuning, high sensitivity, controlled bass and low distortion are intended to make small changes easy to identify and help mixes translate consistently across different playback systems.

At the same time, the MX4 doesn't forget that music is supposed to be enjoyable.

That combination is what makes it interesting for both professionals and serious home listeners.

LCD-MX4 or LCD-X?

This is probably the comparison that matters most.

Both headphones are designed for professional monitoring and critical listening, and both use 106mm planar magnetic drivers.

The LCD-X is Audeze's proven professional workhorse and remains an excellent reference for recording, mixing and mastering.

The LCD-MX4 takes that concept further.

Its Double Fluxor magnetic array produces a 1.5-Tesla magnetic field, while its 105dB/mW sensitivity makes it even easier to drive from professional equipment.

The MX4 also uses a magnesium chassis and carbon fiber suspension headband, keeping weight to 575g compared with 612g for the LCD-X.

If you're looking for the established Audeze studio reference, the LCD-X makes tremendous sense.

If you want to move further up the professional line with greater sensitivity, flagship-derived driver technology and a lighter chassis, the LCD-MX4 is the step up.
