Review on DYTesa Bluetooth 5.0 Audio Receiver, 3.5mm Aux RCA NFC Audio Adapter for Car TV/Home Stereo System, Black – Improved SEO by Carol Miller

Great connection, great reconnection, good sound. There was no ground loop sound. The sound disappears from one speaker or another, but quickly returns. The problem is that the charging port is very tight and this thing actually died trying to connect to the micro USB. (I didn't have it upside down). Also a BIG problem, RCA connectors won't fit unless your cable has an exposed negative signal portion (outer metal on connector). Almost all my cables have this part. Very strange design and I see no reason for it. But if it's a problem, it still has a 3.5mm connector.
