Yealink QD TO RJ9 Cord is a quick-disconnect headset cable designed to connect a compatible QD headset interface to an RJ9 headset port on supported Yealink desk phones. It provides a practical wired connection between headset equipment and the phone’s modular headset interface.
This type of cable is useful for office phone deployments that use professional wired headsets and need a direct QD-to-RJ9 connection. Because RJ9 wiring can vary by phone manufacturer and model, the cable should be matched to the supported Yealink phone and headset configuration before installation.
Key Details and Compatibility
Compatible Headsets: Designed for Yealink YHS34, Yealink YHS34 Lite, and Yealink YHS36 series of corded QD headsets.
Functionality: Features a Quick Disconnect (QD) connector on one end and an RJ9 modular plug on the other, allowing users to quickly step away from their desk without unplugging the headset from the phone.
Automatic Optimization: Automatically optimizes acoustic parameters when plugged into supported Yealink IP desk phones.
Variants: Standard versions are made for Yealink IP phones, while special third-party variants (such as the QD-RJ9-CORD-3PTY) are available for select non-Yealink systems like specific Cisco or Avaya models.
