PRODUCT DESCRIPTION
Yealink YHS34 Mono for 3rd Party QD to RJ Wired Headset (1308089) - 2 Years Local Warranty
Yealink YHS34 QD to RJ9 Wired Headset for Desk Phones
The Yealink YHS34 is a durable, professional wired headset built for desk and IP phones in busy Singapore offices and call centres. The Quick Disconnect (QD) connector lets you step away from your desk mid-call without unplugging, and the plug-and-play RJ9 connection needs no drivers or software.
Single-Ear Wearing Style for Situational Awareness
The mono design leaves one ear free so you stay aware of colleagues around you — ideal for reception desks, service counters and collaborative offices.
QD to RJ9 Headset for Third-Party IP Phones
This version is designed for third-party desk and IP phones, connecting via the included QD to RJ9 cable, so you can standardise on one affordable headset across a mixed phone fleet.
Noise-Cancelling Microphone for Clear Calls
A uni-directional ECM noise-cancelling microphone on a flexible boom arm suppresses background noise and keeps your voice clear with wideband HD audio, so callers hear you, not the room.
Lightweight Comfort for All-Day Wear
A lightweight adjustable headband and replaceable leatherette ear cushions keep the YHS34 comfortable through long shifts — a dependable, cost-effective choice for everyday calling.

Compatibility & Software Support
The Yealink YHS34 is an analog QD-to-RJ9 headset — it connects to your desk phone's headset port, so call platform compatibility is determined by the phone, not the headset. No drivers, software or batteries are required.
- Third-party desk / IP phones: connects to third-party desk and IP phones with an RJ9 headset port via the included QD to RJ9 cable (this is the 3rd-party wiring version — for Yealink phones, choose the standard Yealink version instead).
- Quick Disconnect: the QD connector lets you unplug and walk away without dropping the call.
- Works with any call platform running on your phone system (SIP/UC platforms), since audio is handled by the desk phone.
