Wireless headsets can be so liberating but they only work on regular phones. Well, not any more: what the CS50-USB does for regular phones, the CS50-USB does for your VoIP “soft phone”! You can be up to two hundred feet away from your desk and still receive and end calls as if you were right there.

This 900 MHz system helps keep your conversations secure, and the eight hours of talk time mean that you can go an entire shift without charging or swapping batteries. Fast charge times (1.5 hours for 80% charge; three hours for 100%) nicely complement the noise-canceling microphone, the ability to control volume or even mute the mike, and the headset can be worn four different ways.

Whether you're a hands-on supervisor or your job simply won't let you stay at your desk, this headset can free you to be where you need to be and still stay close to the phone. Don't miss out!
