Meze LIRIC introduces an Earpad Air Flow (EAF) system, developed by Rinaro, which reduces the weight and size of the Liric headphone through optimising its acoustic volume. Precision cut air vents that run from the Liric ear cup chamber into the ear pads allow the MZ4 driver to utilise acoustic volume from the earpads as well as the ear cup chamber. This significantly reduces the required size of the ear cup chamber allowing LIRIC to keep a compact and truly portable closed-back headphone profile without compromising on the acoustic performance.
