I have purchased this package and would like to warn anyone who does so in the future. The outer diameter of the connector socket is smaller than traditional RCA connectors, leaving a loose connection that can be easily disconnected. I've also found that the internal connection is held mostly by the plastic case and isn't consistent. I've attached an image from another answer for illustration. I ended up soldering the ground portion of the two pieces together at their attachment point to keep the ground of the connected wires grounded. I also clamped the socket on the outside of the bottom area so it looks more like an ellipse than a round one so the plugged in cable has a stronger connection to hold on to as they are a bit smaller than usual. The yellow arrows show where I soldered the ground pins from the male part to the female part. Both mods allowed the product to work as intended. However, most of them are not inclined to perform these actions for the product to work properly.
