Overview
About the Yealink DECT Headset + W70B/W90
Ideal for stores or other spaces under 2500 square meters for a single base. Support up to 10 headsets in the system, 5 groups at most, 5 people in a group; 1 preset number for speed dial.
Ideal for places where multi-site coverage is needed, like multi-chain stores. Support up to 250 headsets. Push-to-talk and speed dial are coming soon with exceptional performance.
With Yealink Acoustic Shield technology, the headsets could filter out background noise by 2x microphones while talking, providing HD voice quality and ensuring precise message delivery among store staff.
For those who will wear headsets for a long time, comfort is the primary priority. Yealink headsets feature a lightweight design, soft leather materials, and various earphone sizes to ensure the best possible working conditions.
The DECT base has an indoor connection range of up to 50m and an outdoor connection range of up to 300m, allowing workers to move around freely. And the talk time can ensure all-day use without charging for more worry-free use (WHD622: 14hrs; WHM621: 13hrs; WHM631: 7hrs).
