Problem with blackshark v2 with usb sound card

Hello, I have such an unpleasant problem with blackshark v2 with usb sound card. I connected the headphones immediately with a sound card, synaps 3 was installed before the headphones, at first nothing was clear (the computer identified them as immediately as razer usb sound card speakers) I went to test my ears in discord, but in the end I realized that I was hearing myself, so still in terrible quality. As a result, I deleted synapse, completely reset the audio adapter settings and tried to reconnect the headphones, the result did not change - I heard myself in the headphones, and I hear. The speakers work well, but you can hear some interference if you make the volume higher than average, even with the microphone turned off. I tried to connect without a sound card through a micro jack adapter for a microphone and headphones, everything works without interference, I can't hear myself, in general, everything is exactly the opposite as with a sound card.
