K553 MK2+HM-4

The AKG K553 MK2 and Mackie HM-4 pair a closed-back studio headphone with a compact 4-way distribution amplifier, turning a single monitoring headphone into a setup that shares one audio source across up to four listeners. The K553 MK2's 50mm low-impedance drivers deliver strong, accurate bass and enough sensitivity for precise reproduction on laptops and mobile devices, while a detachable cable and 2D-axis fold flat for easy transport between rooms or locations. The HM-4 takes a single 1/4 inch stereo input and splits it across four 1/4 inch headphone outputs, each with its own level control, so a producer, an artist, and two guests can all monitor the same mix at their own preferred volume. Powered by a 12V AC adapter and built with the same rugged construction Mackie is known for, the HM-4 turns a control room or home studio into a space where more than one person can track or review a mix at once. This bundle suits small studios, project rooms, and teaching setups where multiple people regularly need to listen to the same source without passing a single headphone back and forth.
