Every professional who spends hours on a desk phone knows the problem. Holding a handset against your ear is unsustainable. A speakerphone sacrifices privacy. A poorly made headset compromises audio quality or comfort - usually both. The desk phone deserves a proper headset. Not a compromise. A professional tool.
The Yealink YHS34 Stereo (Dual) is that tool.
This is an analog wired headset designed specifically for desk phones - not a USB headset, not a Bluetooth headset, but a dedicated RJ9 plug-and-play desk phone headset built to deliver HD audio quality, all-day wearing comfort, and hearing protection across the longest call schedules.
Connection is direct and immediate. The YHS34 uses a QD (Quick Disconnect) cable - the standard professional headset connector system that separates the headset from the desk phone cable with a simple twist-and-pull. Connect the included RJ9 cable to your desk phone's headset port, and the YHS34 Stereo is ready in seconds. When you need to step away from your desk briefly mid-call, release the QD connector to disconnect the headset from the cable without ending the call or removing the headset from your head. Return to your desk, reconnect the QD, and you are back on the call.
On Yealink IP phones, this integration goes deeper. The YHS34 is optimised for the full Yealink IP phone range - when connected via RJ9 to a compatible Yealink phone, the phone automatically optimises its acoustic parameters for the YHS34, delivering the best possible audio quality from the combination. The entire Yealink T-series range - T19/T21/T23/T27/T29/T30/T31/T33/T40/T41/T42/T43/T46/T48/T53/T54/T57/T58/VP59/MP56 and more - is directly compatible. The YHS34 also works with a wide range of third-party desk phones including Poly VVX, Snom D-series, and Grandstream GRP/GXP/GXV models.
The stereo (Dual) configuration covers both ears with two 28mm speaker drivers delivering HD Voice wideband audio - 20 Hz to 20,000 Hz, 93 dB sensitivity, 32 ohm impedance. Both ears in means both ears focused. Passive noise isolation from the surrounding environment. Full stereo immersion on calls. For call centre agents and office professionals on high-volume call schedules, stereo wearing reduces listening fatigue compared to a mono headset by distributing the audio load across both ears.
The unidirectional ECM microphone captures your voice with wideband precision (100 Hz to 8 kHz, -44 dBV/Pa sensitivity) while the directional design reduces off-axis background noise. The 330-degree bendable boom arm positions the microphone precisely for left-side or right-side wearing - bend it once to your preferred position and it holds firmly.
ActiveProtection technology guards against acoustic injury - limiting sudden loud audio spikes before they reach the speaker. The independent cavity design of the speaker housing contributes passive noise cancellation, reducing ambient sound that bleeds through the ear cup.
At 129 grams, the YHS34 Stereo is 10-30% lighter than comparable professional desk phone headsets in the same category. Leatherette ear cushions are soft against the ear and create a comfortable passive seal. The ear cushions are user-replaceable - a practical provision for long-term deployments where hygiene maintenance or cushion replacement is a standard operating consideration.
The total cable length of 2.1 metres (0.9m headset to QD connector + 1.2m QD to RJ9) provides adequate reach between a standard desk phone and a seated user without excess cable cluttering the desk.
HD audio. RJ9 plug-and-play. Built for the desk phone, all day.
KEY FEATURES
RJ9 Direct Connection - Plug-and-Play with Desk PhonesThe YHS34 Stereo connects directly to any desk phone's standard RJ9 headset port via the included QD-to-RJ9 cable. Connection is immediate and does not require any drivers, software, or configuration. On compatible Yealink IP phones, the phone automatically optimises its acoustic parameters for the YHS34 upon connection - delivering the maximum audio quality available from the phone-headset combination. The RJ9 connection is the universal standard for analog desk phone headsets and is compatible with the headset port on virtually all current and legacy IP phones.
QD (Quick Disconnect) - Step Away Without Ending the CallThe QD connector between the headset and the desk phone cable is one of the most practically useful features of a professional desk phone headset. When you need to step away from your desk briefly during a call - to collect a document, to speak to a colleague in person, to move to another workstation - simply twist and pull the QD connector to release the headset from the cable. The call remains active on the phone. Return to your desk, reconnect the QD, and you are back on the call within seconds. No hold button required. No missed audio. No disruption to the caller. This is the standard professional headset workflow in contact centres and offices worldwide.
Optimised for Yealink IP Phones - Automatic Acoustic OptimisationWhen connected to a compatible Yealink IP phone, the phone automatically detects the YHS34 and optimises its internal acoustic processing parameters to match the headset's audio characteristics. This provides a higher-quality audio output than the same headset connected to a third-party phone - the phone and headset work together to deliver the best possible call audio. Compatible Yealink models include the full T-series range: T19(P)E2, T21(P)E2, T23P/G, T27G, T29G, T30/P, T31/P/G, T33P/G, T40P/G, T41S, T42S/U, T43U, T46S/U, T48S/U, T53/W, T54W, T57W, T58A, VP59, and MP56.
Dual 28mm Stereo Speakers - HD Voice Wideband AudioTwo 28mm speaker drivers - one per ear cup - deliver stereo HD Voice audio across the full 20 Hz to 20,000 Hz frequency range at 93 dB sensitivity. Wideband audio reproduces voice with greater natural breadth and detail than narrowband systems - voices sound more natural, nuance and intonation come through clearly, and the quality of extended call sessions improves measurably. The stereo configuration distributes audio across both ears, reducing the listening fatigue that accumulates in a mono headset during long call schedules.
Noise-Cancelling Unidirectional ECM MicrophoneThe unidirectional ECM microphone captures your voice with wideband precision (100 Hz to 8 kHz, -44 dBV/Pa sensitivity) while its directional design reduces the pickup of off-axis background noise. In open-plan offices and contact centre environments where multiple simultaneous conversations create a complex acoustic environment, the directional microphone reduces background noise transmission while preserving the natural quality of your voice.
330-Degree Bendable Boom Arm - Left or Right, Any AngleThe boom arm bends through 330 degrees and holds its position once set - no spring-back, no loosening over time. Position the microphone precisely where it captures your voice best, on whichever side of your face you prefer. The bendable mechanism is more durable and position-stable than rotating plastic arms, maintaining its set angle reliably over years of daily use.
ActiveProtection - Hearing Safety During CallsActiveProtection technology monitors audio output and intercepts sudden loud sounds - unexpected audio spikes, line noise, or abrupt volume changes - before they reach the speaker. This protects against the acoustic injury risk that is particularly relevant for professionals on high-volume call schedules, where exposure to an unprotected audio spike can cause immediate discomfort and contribute to long-term hearing damage. ActiveProtection operates silently and continuously throughout every call without any configuration required.
Independent Cavity Design - Passive Noise CancellationThe speaker housing uses an independent cavity design - an acoustic isolation architecture that limits the amount of ambient environmental noise that bleeds through the ear cup to reach the listener. Combined with the physical seal of the leatherette ear cushions, this produces a noticeably quieter listening environment inside the headset than the surrounding space - improving focus and reducing the cognitive load of filtering out background sounds during calls.
129 Grams - 10-30% Lighter Than Comparable HeadsetsAt 129 grams, the YHS34 Stereo is 10-30% lighter than comparable professional desk phone headsets in the same category. The low weight distributes naturally across the headband with minimal pressure on the top of the head - enabling comfortable wearing through long contact centre shifts and all-day office use.
Leatherette Ear Cushions - ReplaceableSoft leatherette ear cushions create a comfortable passive seal against the ears, contributing to the headset's passive noise isolation and providing a durable, easy-to-clean surface for daily professional use. The ear cushions are user-replaceable - available as accessories - allowing the headset to be kept comfortable and hygienic over its full working life, and making the YHS34 a sensible long-term investment for organisations with hygiene replacement policies.
2.1-Metre Total Cable LengthThe YHS34 Stereo has a 0.9-metre headset cable from the headset to the QD connector, and a 1.2-metre QD-to-RJ9 cable from the QD connector to the desk phone - 2.1 metres in total. This provides adequate reach for standard desk configurations where the phone is positioned at the side or back of the desk, without creating excessive cable management issues at a standard workstation.
Wide Third-Party Desk Phone CompatibilityIn addition to the full Yealink IP phone range, the YHS34 connects via RJ9 to a wide range of third-party desk phones - including Poly VVX x01/x10/x50, Snom D3xx/D7xx, and Grandstream GRP/GXP/GXV models. For the complete compatibility list, refer to the Yealink Headset Compatibility Guide.

FREQUENTLY ASKED QUESTIONS
Q: What is a QD (Quick Disconnect) connector and how does it work?
A: A QD connector is a small, twist-and-pull disconnect point built into the cable between the headset and the desk phone cable. When you need to step away from your desk - to collect a document, speak to a colleague, or briefly leave your workstation - you twist and pull the QD connector to separate the headset from the cable without ending the call or removing the headset from your head. The call remains active on your phone in a paused state. When you return, push the QD connector back together with a click and the call audio reconnects instantly. This is the standard professional headset workflow in contact centres worldwide, and the YHS34's QD connector is fully compatible with the industry-standard QD pin configuration.
Q: Does the YHS34 connect to a computer or USB port?
A: No. The YHS34 is an analog desk phone headset - it connects via the RJ9 headset port on your desk phone only. It does not have a USB connector and does not connect to computers, laptops, or softphone applications directly. For a USB computer headset, the Yealink UH34 range provides the same ergonomic design and audio quality in a USB-connected format compatible with PC softphones and UC platforms.
Q: What is the difference between the YHS34 and the YHS34 Lite?
A: The headset hardware - speaker drivers, microphone, boom arm, ActiveProtection, independent cavity design, cable lengths, and compatibility - is identical between the YHS34 and YHS34 Lite. The only difference is the ear cushion material. The standard YHS34 uses leatherette ear cushions - providing a better passive acoustic seal, a more durable covering that resists wear over time, and an easier-to-clean surface for hygiene maintenance. The YHS34 Lite uses foam ear cushions - providing a softer initial contact feel and better breathability in warm environments or long sessions. The Lite is also slightly lighter at 111g versus the standard YHS34's 129g. Choose the standard YHS34 for better passive isolation and long-term cushion durability. Choose the Lite for maximum breathability and softer initial comfort.
Q: How does the automatic acoustic optimisation on Yealink phones work?
A: When the YHS34 is connected to a compatible Yealink IP phone via RJ9, the phone detects the headset and automatically adjusts its internal audio processing parameters - equalisation, gain, and acoustic settings - to match the specific characteristics of the YHS34's speaker and microphone. This provides better audio quality than using a generic headset profile, which the phone would apply to an unknown third-party headset. The result is a more natural, optimised audio experience that uses the combined capabilities of both the phone and the headset more effectively. This optimisation is exclusive to Yealink IP phones and does not occur when the YHS34 is connected to third-party desk phones.
Q: Why choose stereo (Dual) over mono for a desk phone headset?
A: A stereo dual-ear headset covers both ears, providing full passive isolation from the surrounding office environment and distributing audio across both ears. This reduces the listening fatigue that accumulates in a single-ear mono headset during long call sessions - because the audio load is shared between two speakers rather than concentrated in one. For contact centre agents on back-to-back calls throughout the day, stereo wearing is generally more comfortable and less fatiguing over an eight-hour shift. The Dual also provides better passive noise isolation from floor noise, helping agents concentrate on calls in busy environments. The mono version is the correct choice for professionals who need to remain aware of their surroundings during calls - to hear supervisors, colleagues, or environmental activity.
Q: Are the ear cushions replaceable?
A: Yes. The leatherette ear cushions on the YHS34 Dual are user-replaceable - available as accessories from Yealink and authorised resellers. For contact centres with hygiene replacement policies, or any deployment where cushion quality needs to be maintained over time, replaceable cushions significantly extend the headset's useful working life and reduce total cost of ownership.
Q: What warranty does the Yealink YHS34 come with?
A: The Yealink YHS34 is covered by Yealink's standard manufacturer warranty. Please confirm current warranty terms with your retailer at time of purchase. A 12-month warranty is the standard term noted by international resellers.
