Yealink YHS34 Lite Dual for 3rd Party QD to RJ9 Wired Headset

Overview :

The Yealink YHS34 Lite Dual for 3rd Party is a professional over-the-head binaural wired headset designed for office, SOHO, and contact center environments. It is specifically engineered for compatibility with non-Yealink IP phone ecosystems such as Cisco and Avaya through a QD-to-RJ9 wired interface.

This headset is part of the YHS34 family, which uses a modular Quick Disconnect (QD) design connected to an RJ9 termination cable, enabling plug-and-play deployment with desk phones without requiring USB or Bluetooth infrastructure.

It delivers wideband HD voice performance with a 28 mm speaker driver and a noise-canceling microphone, making it suitable for high-volume voice communication environments such as call centers and enterprise reception desks.

The “Lite” variant uses lightweight foam ear cushions, optimized for long-duration wear in continuous calling environments, while the dual-ear (binaural) design improves focus in noisy workplaces.

This model is not intended for UC softphone use (USB/Bluetooth). It is strictly designed for desk phone telephony deployments where analog RJ9 headset ports are available.
