Meze Audio Liric closed back headphones

Gently used for about a year.  In excellent condition.  They look new and sound amazing.  Comes in original box with case and two cables plus the product manual.  
 

• Closed-back Isodynamic hybrid planar headphones
• Custom MZ4 Isodynamic Hybrid Array driver developed by Rinaro
• Detailed sound, tonal balance leans towards neutral, small emphasis in lower bass
• Easy to drive but responds well to larger amounts of power with strong performance from Balanced input

ULTRA LOW DISTORTION
Total harmonic distortion (THD) measures under 0.15% in the entire range.

LIGHTWEIGHT
71g combined driver weight designed to create a headphone that offers comfortable listening on the go.

Phase-X™ SYSTEM
Improved ambience and spatial sound imaging through innovative technology.
Patent pending.

ULTRA HIGH RESOLUTION AUDIO
Upper frequency limit of audio reproduction is 92,000 Hz.

EASY-TO-DRIVE
100dB@1mw/1kHz; 30Ω
Can be driven by almost any portable source without needing amplification.

 

ADVANTAGES OF A DUAL-DRIVEN SYSTEM

The MZ4 driver combines individual switchback and spiral shaped voice coils within the same diaphragm allowing sound to be targeted with more accuracy around the natural form of the ear:

SWITCHBACK COIL
The switchback coil is more efficient at reproducing lower frequencies and is positioned in the upper part of the driver.

SPIRAL COIL
The spiral coil is more efficient at reproducing middle-high frequencies and is positioned directly over the ear canal enabling more direct sound waves to enter the ear without any time delays.

ISOPLANAR DIAPHRAGM MATERIAL
The diaphragm is manufactured from a custom developed isotropic thermally stabilized polymer with a conductive layer. Through unique processing methods, an ultralight yet rigid diaphragm has been achieved.

IMPROVED EFFICIENCY AT HIGHER FREQUENCIES
At frequencies above 10kHz where sound wave length is smaller than the cushion's inner cavity, the sound field becomes diffused with an amount of direct and reflected sound waves within the ear canal.

PHASE-X™, A REVOLUTION IN SOUND IMAGING

An innovation to the MZ4 driver is the Phase-X™ system created by Rinaro as a way to minimize phase distortion issues, typically found in closed-back headphone designs. This patent-pending technology helps deliver an immersive spatial sound imaging.
