Got these recently after finally deciding to ditch cables. The units feel solidly built and look good. They are surprisingly small and unobtrusive which I prefer. I have only used them at home so far, but no issues regarding noise interference etc. The sound is excellent and it may just be my imagination, but it’s actually better than my cables (Klotz,neutrik etc). So far so good, the feeling of being uncluttered and free from cables is great, just wish I’d done it earlier! I believe in the saying “buy cheap buy twice”. On initial assessment I think these are well worth the outlay!
