Wired Dual-Headset Yealink YHS34 Lite by Yealink — dual-ear wired headset with boom microphone

Yealink YHS34 Lite is a wired dual-ear headset designed for professional voice communication. The dual-ear (supraaural) design provides focused audio for calls and meetings while the boom microphone ensures clear voice pickup. The headset uses a 0.9 m cable, head-band wearing style and comes in black. It is intended for use with Yealink desk phones where a QD to RJ9 plug-and-play connection enables immediate operation and phone-side acoustic optimization for the headset.

Advantages

The YHS34 Lite offers a high signal-to-noise ratio speaker and an independent cavity design to reduce background noise and improve speech intelligibility. Passive noise cancellation and a boom microphone support clearer conversations in office and contact-centre environments. The model is engineered for comfort with soft ear cushions and ultra-lightweight materials, making it suitable for prolonged use; it is specified to be noticeably lighter than many comparable headsets. Direct compatibility with Yealink phones simplifies setup and ensures optimized audio settings out of the box.

Suitable for

• Office desk phone calls and unified communications where wired reliability is required
• Contact centre agents needing focused audio and clear microphone pickup
• Remote work setups using Yealink IP phones for frequent voice calls
• Meetings and conference calls that benefit from a dual-ear (stereo) headset

When it may not be suitable

The wired 0.9 m cable and RJ9/QD connectivity require a compatible desk phone and limit mobility compared with wireless headsets. It may not be suitable for users who need long free movement away from their desk or for devices that do not provide the required RJ9/QD interface.

How to use

Connect the YHS34 Lite to a compatible Yealink desk phone using the supplied QD to RJ9 cable; the headset will operate immediately without additional drivers. Position the head-band comfortably and adjust the boom microphone so it sits near the corner of your mouth but not directly in front of it to reduce breath noise. Use the phone’s audio controls to adjust volume and accept that the phone may automatically apply optimized acoustic parameters for best voice clarity. Store the headset in a clean, dry place when not in use.

What to consider before purchase

• Confirm your desk phone supports QD to RJ9 connections or that you have the appropriate adapter
• Assess whether a wired headset with a 0.9 m cable fits your workspace and mobility needs
• Consider dual-ear (supraaural) wearing style versus mono options for situational awareness
• Check compatibility with your specific Yealink phone model for automatic acoustic optimization

Usage recommendations

For best voice quality, align the boom microphone near the mouth corner, keep the cable routed to avoid strain on the connector, and use the Yealink phone’s audio settings to fine-tune volume and noise reduction. Regularly clean ear cushions with a dry cloth and replace them as needed for hygiene and comfort.
