Good headphones for the money. So far, there are no global complaints. Confuses the location of the usb-card in front of the port itself. When you insert a small piece of wire between the input and the card into the usb port, it is constantly bent under the weight of the card. Adjusting the volume on the earpiece for an amateur. The fighters are satisfied with the quality of the microphone "you speak as if directly into the head"
