The Motorola SYN1075A is a replacement pendant for HS830. The HS830 plugs into the audio jack on the neck strap headset and has a built in earbud on the cord for easy storage and a clean look when not in use. This flexible solution is perfect for those who prefer an earbud versus on-the-ear wireless headsets. The multifunction button allows users to place, receive or end calls, all with one simple push -- freeing you up to focus on the road or walk ahead. Headset Not Included.
