Experience Modern Voice Communications

The new-gen T4U series greatly improves the call experience and work efficiency with dual USB ports, Ultra HD sound quality, faster response speed, and even more advanced features. The new T4U series will be a powerful
assistant for modern business.

Distraction-Free HD Communications

The Yealink T4U series provides distraction-free communications with Yealink’s industry-leading Acoustic Shield Technology. Moreover, by leveraging Yealink’s Optima HD audio technology, and the addition of Opus to its broad audio codec list, Yealink’s new T4U series guarantees HD sound quality and a distortion-free communication experience.

* By supporting Opus, the Yealink T4U series delivers better audio quality in both high-bandwidth and poor network conditions, compared to other wideband or narrowband codecs.

Dual USB Ports, Strong Scalability

All T4U models are equipped with dual USB ports, meaning the entire series allows users to connect two Bluetooth dongles, Wi-Fi dongles, EHS40 headset adapters, USB headsets or USB disks at the same time. With dual USB ports, the new T4U series flexibly adapts to various scenarios and demands.

Color Expansion Module EXP43

Equipped with Yealink’s new EXP43 expansion module, the new T46U/T48U offers a full-color experience, while the former EXP40 only supports grayscale color mode. Moreover, when the EXP43 connects to the T43U grayscale phone model, the interface automatically switches to grayscale mode, making it more unified.
