Same summary

The HP Poly CS540A DECT Headset is designed for those who spend most of their time on calls—whether in a modern office or working from home. The mono design allows you to still be aware of what's happening around you, which is important for many, especially in a dynamic work environment. With a wireless connection and a range of up to 120 m, they allow freedom of movement, but they are not suitable for demanding music listening or for users looking for complete sound isolation. The built-in microphone ensures clear communication, but the single earpiece makes the product less suitable for those who want to be completely immersed in the content.
