The Logitech H820E Mono is a wireless headset with a single ear piece that combines high quality with user-oriented design. It is ideal for employees who need to stay aware of their surroundings while enjoying wireless freedom during conversations. The light is located on the back of the headband, allowing people behind you to see that you are on a call and do not wish to be disturbed. An additional LED light on the microphone boom indicates whether the microphone is muted or not. The base also features a light that, along with an acoustic signal, alerts you to incoming calls. The ear cup includes controls for managing the call, answering or ending the call, and adjusting the volume.

The raised buttons serve as a reference point for your fingers, allowing you to feel them when pressed. The headband itself is equipped with a leatherette cushion, ensuring comfort even during long wear. The microphone boom can be easily flipped up. H820E headsets automatically pair when connected to an H820E charging station, making them easy to use with any workstation for extensive deployments or hot-desking.

Acoustic echo cancellation and the noise-canceling microphone ensure that you can hear and be heard well, even in noisy workplaces. Digital Signal Processing (DSP) allows for precise adjustment of the microphone and speaker for more lifelike conversations. A switch provides the option to switch to narrowband to enhance performance in high-density environments and extend talk time.
