The Sandberg Bluetooth Headset ANC FlexMic is a wireless headset that meets high standards. Thanks to its elegant and, above all, comfortable ear cups, the headset is pleasant to wear for many hours. The integrated ANC function (active noise cancellation) ensures that the excellent sound quality is not disturbed by ambient noise, whether you're sitting in a noisy office or exposed to the constant low-level noise on a plane or train. The detachable, flexible microphone arm captures your voice perfectly, whether during online conferences, gaming, or internet calls. Even when the microphone arm is not attached, you can speak directly into the built-in microphone in your headset. The integrated battery can be easily charged via USB anywhere. Once charged, your headset offers a continuous operating time of up to 13 hours.
