The CC 520 binaural headset offers powerful, precise sound to both ears for maximum concentration on your calls. The sturdy construction paired with the self-adjusting wearing style makes this a great headset for all-day use.

When paired with the quick disconnect cord, this headset is a great solution for use with many corded office phones with internal amplifiers. If you're unsure whether your phone has an internal amplifier, give us a call at 1-800-HEADSETS (1-800-432-3738), and we'll be happy to check on compatibility for you.
