Audio4c noise floor

THOSC

I hear a distinct background noise with my new Audio4c. Only the power supply and the headphones are connected. I can not explain this, since it is praised in comments and tests in this regard. Connected to the PC, the noise remains, even a reset did nothing, the software is up to date. With my Steinberg UR22mk2 I hear no noise at all with the same headphones. However, that does not require a power supply.

Is the noise normal?

I'm having the same problem with my Audio4c. I don't have any inputs plugged in, but there's a constant noise any time I set the Audio4c as the audio input, and then as soon as I switch to another audio input the noise level drops significantly.
