Sound like the Pro you are with the Plantronics CS55H Home Edition Wireless Headset System for your home cordless or corded phone. We've combined the clarity of traditional corded technology with the hands-free mobility of wireless, so you can move around your home (up to 300 feet) without interrupting or missing a call. The CS55H uses 1.9GHz voice-dedicated wireless technology, greatly reducing interference. Conversations are much easier and professional thanks to the noise-canceling microphone that filters out unwanted noises. You'll come through loud and clear to your clients and colleagues while eliminating the distraction of barking dogs, the doorbell, or your family's voices.
