Audeze LCD-X

Audeze’s more neutral, easier-to-drive planar flagship: full and punchy without the LCD warmth tilt.

Our take

The LCD-X is the studio-leaning Audeze: the planar weight and slam, but flatter and more neutral than the LCD-2/3, with a livelier top. Lower impedance and higher sensitivity make it easier to drive than most planars, though it still wants real power to slam.

Measured on a Head Acoustics HMS II.3 artificial head — raw response, left/right averaged, normalized to 0 dB at 1 kHz. From the Sonic Temple Archive(2008–2014, one unit per model). Honest limits: seating variance runs ±0.4 dB in the mids to ±3.9 dB above 12 kHz, and open headphones read bass-light on this fixture — don’t read fine treble detail as settled. How we measure →

Common questions

Straight answers — the same ones our measurements support.

Does the Audeze LCD-X need an amp?

Yes for its best slam, though it is easier to drive than the LCD-2/3.

LCD-X vs LCD-3?

The X is flatter and more neutral with a livelier top; the 3 is warmer and lusher. X for work, 3 for warmth.

If you like the LCD-X

Close on the graph, or a deliberate step in one direction.
