Poly EncorePro Y-Training Cable with Quick Disconnect Lock

The Poly 85S09AA is a Y-training cable for EncorePro headsets that lets a trainer and a trainee share the same call without complicated setup. By plugging two headsets into one adapter, a supervisor can listen in, offer real-time coaching, and keep conversations on track, which is especially valuable in call centers, technical support teams, or customer service classrooms.

A red toggle switch sits at the center of the cable and makes it easy to choose which microphone is live. With a quick slide, a supervisor can take over the conversation or let the trainee speak, so transitions stay smooth and professional.

The cable uses Poly’s 6-pin Quick Disconnect and adds a locking mechanism that resists accidental pulls. This connection style protects call quality and lets agents move freely without worrying about dropped audio.

Because the cable measures only about 8 inches and weighs roughly 1.84 ounces, it stays out of the way and keeps the desktop clear. Trainers can carry it between workstations or pack it in a laptop bag without adding noticeable bulk.

Whether you are onboarding new hires, running quality assurance sessions, or offering live coaching to seasoned agents, this simple accessory creates an efficient path to better calls and faster learning.
