»Sandberg has taken care to incorporate the highest quality construction materials into the Business Pro Bluetooth, giving particular importance to the Bluetooth headset which undoubtedly stands out for its amazing application. But apart from the excellent design, the microphone of the BT headset stands out for another reason, as it has a noise cancellation feature, which means that it has a series of special filters that remove the noise of the natural environment heard in the background. The audio result is… crystal-clear, enabling you to hear your interlocutor loud and clear.«
