The ATH-PACK5 gives you a set of five M-Series headphones to cover all your professional monitoring and mixing needs – and at a reduced price, too. The pack includes one pair of our critically acclaimed ATH-M50x professional monitor headphones, which provide exceptional clarity throughout an extended frequency range, with deep, accurate bass response. Designed as a critical listening tool for the most demanding audio professionals, the M50x headphones feature 45 mm drivers, 90° swivelling earcups, a collapsible design and three detachable cables (1.2 m - 3.0 m coiled, 3.0 m straight and 1.2 m straight). The PACK5 also includes four pairs of ATH-M20x professional monitor headphones that can be used by musicians or others participating in a session. With 40 mm drivers tuned for enhanced low-frequency performance, the M20x headphones are conveniently designed with a single-sided cable and, like the M50x, feature robust construction and circumaural earcups for excellent sound isolation and comfort.
