Bold JBL design and premium finishing From the brushed stainless steel headband and ear-cup accents to the matte black or white housings, from the embossed, metallic JBL logos to the cable that matches the ear pads, these headphones are designed to be as pleasing to the eyes as they are to the ears. Premium, high-performance JBL drivers JBL drivers deliver precise, powerful sound for an exceptional listening experience. Bass is pure, deep and accurately produced ? the calling card of legendary JBL sound. As a result, J55s outperform competitive products costing much more. Rotating, 180-degree DJ pivot mechanism Sometimes you need to be aware of more than just your music. J55 ear-cups rotate up to 180 degrees while you?re wearing them so you can keep one ear on your audio and one ear on external sounds or conversations. The ear-cups rotate under the headband for easy storage and transport. Soft leather ear cushions Our ear cushions feature a soft leather that provides longwearing comfort. It also helps maintain an acoustic seal on the ear, which improves the headphones? passive noise reduction. And that means a purer listening experience. Closed-back design J55 headphones feature a closed-back design that blocks ambient noise and minimizes leaking. So the outside noise stays outside, and your listening experience stays yours and yours alone. Single-side, detachable cable Tangled cables are a constant source of frustration. But not with the J55s. The tangle-resistant, flat elastomer cable connects to just one ear-cup, which further minimizes tangling. The cable also detaches from the ear-cup for added flexibility. Cable-locking mechanism A unique, twist-lock mechanism keeps the detachable cable secure when it?s connected. When you plug the cable into the ear-cup, a simple twist locks it in place.
