With the Jabra Evolve 75, you can enjoy the freedom of being able to leave your desk during a call. The wireless Bluetooth 1 technology offers you up to 30 metres of hands-free connectivity to your PC, smartphone and tablet. Enjoy up to 15 hours of talk time on a single charge. Or simply use the USB cable and charge the headset during use. You can switch on active noise cancellation to eliminate virtually all low-frequency noise (e.g. the hum of the air conditioning). Active noise cancellation uses sophisticated microphones to monitor and reduce disturbing noises. When the "Busylight" of the Jabra Evolve 75 lights up red, it indicates to your colleagues that you are on a call. In this way, it ensures that you are not disturbed. You can also activate the Busylight manually so that you can work undisturbed. Thanks to dual connectivity with two Bluetooth-enabled end devices, users can make calls and listen to music via one and the same headset. The model has a wireless range of up to 30 metres, independent of the smartphone and/or PC. Comfortable ear cushions with a leather feel for a fit that rests on the ear and all-day comfort.
