Poly Y Training Adapter Cord

The Poly 85S07AA is a Y-shaped training adapter cord that lets two headsets with Quick Disconnect connectors share a single phone or USB audio path. It gives trainers and supervisors an easy way to listen in, coach, and take over a call without swapping cables or interrupting the conversation.

An inline module on the cord includes a mute switch that toggles which microphone is live. A supervisor can step in to handle a sensitive moment, or stay muted while the trainee manages the call. This control makes real-time coaching smoother and more discreet.

The adapter works with Polaris headsets, DA Series USB adapters, and QD amplifiers that use the standard Poly Quick Disconnect interface. Because it follows the established Poly wiring, you can add it to an existing contact center or office setup without changing phones, headsets, or software.

The cable measures seven feet, giving both users room to sit comfortably and arrange their equipment without strain on the connectors. Poly builds the cord to withstand everyday use in busy environments such as customer support desks, sales floors, and technical help lines.

Whether you are onboarding new agents, running quality-assurance sessions, or coaching experienced staff on complex calls, the Poly 85S07AA delivers the shared audio path and mic control you need for productive training.
