Yealink Network Technology Co., Ltd USB/QD Trainer Cable for YHS34 YHS36 RJ9 Headsets

Trainer Cable for YHS34 and YHS36 Headsets

This USB/QD trainer cable connects Yealink YHS34 and YHS36 RJ9 headsets to a host device for dual-listening scenarios. It is intended for supervisors, trainers or quality-assurance staff who need to monitor live calls without interrupting the primary user. The detachable design allows the cable to be removed when monitoring is not required. The black cable measures 9.84 inches in length and weighs 1.28 ounces.

Integrates with Existing Headset and USB Port

The cable uses a male-to-male connector arrangement with four contact points to bridge the headset's RJ9-style quick-disconnect port and a standard USB interface. No additional adapters or driver installations are mentioned, so the connection relies on the host recognising the headset's native USB audio profile. Its short length keeps the tether close to the workstation, freeing up desk space and reducing cable clutter around the user's immediate area.

Maintains Passive Signal Path During Extended

Because the assembly contains no active electronics, it adds no latency, noise or power draw to the audio path during prolonged monitoring sessions. The detachable joint can be separated repeatedly without degrading the electrical contact, supporting frequent connect-disconnect cycles typical in shift-based training environments. The lightweight construction avoids strain on the headset's quick-disconnect latch even when the cable remains attached for full working days.
