Plantronics M10 Telephone-to-Headset Adapter Volume Headset Mute Controls
The Plantronics M10 is a desktop in-line adapter that connects a corded headset to a standard desk telephone handset port, adding independent roller-wheel controls for volume, headset activation, and mute directly on the desktop unit.

Applications
The Plantronics M10 was designed for office environments where workers need hands-free telephone operation using a corded headset. It connects between a standard analog desk phone and a Plantronics corded headset, giving the user volume adjustment and mute capability at a convenient desktop control unit rather than on the handset itself. The DIP switch bank on the underside allows the adapter to be configured for compatibility with a wide range of telephone models. The M10 dates from the early 1990s and was widely used in call centers, reception desks, and office workstations of that era. It remains a practical solution for anyone still operating legacy analog desk phones with Plantronics corded headsets.
This Plantronics M10 Telephone-to-Headset Adapter has been inspected and appears to be in good used condition. The housing shows light surface dust and minor scuffing consistent with normal office use. All three roller controls — volume, headset, and mute — are present and move freely. The RJ-11 and DC jacks on the rear appear clean and intact. Please view our photo set and contact us if you have any questions.
