Fine for the price
I've been using several of these transformers for audio isolation in communications applications, for as long as 16 years, and have had no problems at all. At the price, they are surprisingly good. They sound subjectively OK in applications where high audio quality is not an issue, and seem to handle 0dBm, or even +4dBm, without obvious distortion. They are amazingly spec'd by Calrad at 20-25kH
