The GN Netcom 2125 Flex Dual Headset delivers superb sound quality, more comfort than ever, and dual speakers to shut out background noise. To truly appreciate the design, you have to try it on. You'll be delighted to discover that it feels as good as it looks! Lightweight and well balanced, it features a click-stop headband that provides a customized fit. The pillow-soft ear cushions rest gently over both ears. The sound quality is great, too! The advanced noise-canceling microphone and dual ear speakers filter out surrounding sound, so only the speaker's voice is transmitted. Plus, you can hear the person on the other end of the line better as well. That helps you maintain a professional image on your calls and makes it easier for you and your party to be clearly understood. Use this headset with GN Netcom corded or wireless amplifiers.
