Yealink UH34 Mono UC Wired USB Headset USB-A
PRODUCT DESCRIPTION
Yealink UH34 Mono UC Wired USB Headset USB-A (1308042) - 2 Years Local Warranty
Yealink UH34 Wired USB Headset for Business Calls in Singapore
The Yealink UH34 Mono UC is a plug-and-play wired USB headset built for everyday office calls, contact centres and unified communications. The single-ear design keeps you aware of your surroundings in busy, open-plan Singapore offices, while the 28 mm wideband speaker delivers clear, natural call audio all day.
UC Version for Every Softphone Platform
The UC edition works across Microsoft Teams, Zoom, 3CX, RingCentral, Unify and most USB softphone platforms, giving your team one consistent headset for every call. Its controller includes a voice-assistant button in place of the Teams button found on the MS edition.
Noise-Cancelling Microphone on a 320° Bendable Boom
The uni-directional ECM noise-cancelling microphone suppresses background noise so callers hear you, not the room. Passive noise cancellation and Yealink ActiveProtection hearing protection (110 dB acoustic limit) keep every conversation clear and safe.
Lightweight 88 g Comfort with Inline Call Control
At approximately 88 grams with a padded headband and soft leatherette ear cushion, the UH34 Mono stays comfortable through long shifts. The inline controller handles answer, end, reject, hold, volume, mute and redial — no reaching for the keyboard, no charging ever required.

Frequently Asked Questions — Yealink UH34
What is the difference between the UC and MS Teams versions?
The UC version has a voice-assistant button and is optimised for general softphone use. The UH34 Mono MS Teams is certified for Microsoft Teams and adds a dedicated Teams button.
Should I choose Mono or Dual?
Mono keeps one ear open — ideal for reception desks and collaborative teams. The UH34 Dual UC covers both ears for focus in noisy, open-plan offices.
What is the difference between the UH34 and the UH34 SE?
They share the same core audio platform (28 mm wideband speaker, noise-cancelling ECM mic, ActiveProtection). The UH34 SE is the value edition and is also offered in USB-C variants.
Does the UH34 need charging?
No. It is a wired USB-A headset — fully powered by the USB port, with no battery to charge and no drivers to install.
How does the UH34 compare to the newer Yealink UH35/UH42?
The UH35 and UH42 are newer models with a combined USB-C/A connector. The UH34 remains the proven, budget-friendly workhorse for USB-A deployments.
Does the UH34 come with local warranty?
Yes. Every UH34 sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
