Description
The Yealink W78H is an add-on cordless handset with built-in Bluetooth 5.1 and a 3.5 mm headset jack, and it needs a compatible Yealink DECT base such as the W70B. It suits offices, retail floors and front desks where staff take calls on a headset while moving around. A vibration alarm and a 2.4" color screen set it apart from the basic handsets.
Key features

Specs are Yealink's, from its current data sheets. Systems show the handset in the box. Range and battery figures are Yealink's "in ideal conditions" numbers, and some handsets list two figures for different hardware versions (V0 to V4). "None listed" means the data sheet names no such feature. Compare all W Series models
