510 JBL iPod Headphones

The world can be a noisy place, often filled with people who didn’t get the memo about cell phone courtesy. That’s why JBL developed Reference 500 Series noise-canceling headphones. Now you can concentrate on your favorite music in all its full-spectrum glory, without the distraction of all the commotion around you. Choose a compact, on-ear model that automatically blocks out up to 70% of ambient noise, or an over-ear design that lets you dial up your preferred level of glorious silence, from library-like to complete-and-total.
