Two celebrated names from the UK audio scene – audiolab and ACS – have teamed up to deliver a range of British-made, multi-driver in-ear monitors called audiolab M-EAR. The M-EAR 2D is a two-way, two-driver design, with one driver handling mid/high frequencies and the other dedicated to bass. The M-EAR 4D is a three-way design sporting four drive units – one for high frequencies, another for midrange and two for bass.
