Review on BEHRINGER UM2 Audio Interface with XLR/TRS, 1/4", USB, and RCA – Black, 1-Channel by Li Mei ᠌

I bought it less than a month ago and immediately wrote a return request to the store, because I have never encountered anything like this on other similar devices. By itself, the sound output through the line-out and through the headphones is clean, without much noise. But at the inputs it makes noise like the wind . Even with empty inputs without load, the noise level fluctuates between -70 and -60 dB. This is very bad. I have another sound card, though more professional, so you can’t even hear or see noise on it without load. This one makes noise on its own.
