The CS540 Bundle Wireless Office Headset System combines the clarity and performance of traditional corded technology with the hands-free convenience of wireless mobility. Featuring DECT 6.0 and advanced noise-canceling technologies, this business-class headset system offers superior audio performance and a roaming range of up to 300 feet. Add to the mix a talk time of up to 10 hours on a single charge, a handset lifter that lets users answer and end calls away from the desk, and a headset design that can be converted to over-the-ear, over-the-head, or behind-the-head wearing styles, and the result is a wireless headset system that takes communications and multi-tasking to a whole new level.
