blackshark v2 hyperspeed bug

Ok so this is strange and doesn’t bother me at all but when I plug my headphones into my ps5 and charge it while playing there is a faint music playing in my right ear and I’ve checked everything on my ps5 I even disconnected it from my internet and it still played only while plugged into my PlayStation again this doesn’t bother me at all and it doesn’t do it when I use the Bluetooth thing but I just thought it was strange
