This is the next generation wireless headset system that lets you take the conversation wherever you need to go up to 300 feet away from the base unit. All day Freedom and Convenience Walk and talk for up to eight hours on the phone without having to recharge your headset. This headset uses digital 900 MHz technology to deliver calls that are clear, private and completely secure. This headset has an integrated IntelliStand that makes wireless mobility as easy as answering the phone - pick up the headset and you pick up the call. And when you're away from your desk, you are still in touch to think and talk on your feet, either answering or ending a call with the touch of a button.
