Drawing on expertise learned from building some of the world’s finest loudspeakers, JBL® engineers have created lightweight, on-ear headphones with a fresh look and uncompromising sound. The J55a drivers generate pure, accurate, extended bass that competing products can’t touch. Their superb clarity enables you to hear the truth from your music. Our unique DJ-pivot mechanism lets you rotate either ear cup up to 180 degrees, so one ear can hear outside sound. A one-button mic/remote lets you take Android™ calls without taking the headphones off. And bold styling makes J55a headphones both an aesthetic and acoustic triumph.
