Drawing on expertise learned from building some of the finest loudspeakers in the world, JBL engineers created lightweight, over-ear headphones with a fresh look and uncompromising JBL sound. The J55’s premium drivers generate clarity and extended bass that competitive products simply can’t touch. Pure, accurate bass lets you hear the truth from your music. The unique, DJ pivot mechanism lets you rotate either ear-cup up to 180 degrees, which frees up one ear to hear outside sound. Bold styling details, including brushed stainless steel ear-cup and headband accents, make J55 headphones an aesthetic, as well as acoustic, triumph.
