Creative pebble speakers emitting a dog whistle like noise

I bought some cheap speakers ($22) on Amazon for an alternative for relaxing and when I connect the USB and the audio jack a very quiet and hardly noticeable screech is played along with my audio (but of course once you notice it you can always hear it). Is the quality to blame or is the error on my side?
