Thanks to its multi-connectivity, you can connect it either via USB-A or USB-C to a computer, and even to a 3.5mm jack on a phone or tablet for example.
In terms of comfort, the ear cushions have a leatherette coating.
The microphone is equipped with a system that eliminates "parasitic" conversations that occur in your environment.
