These RCA plugs looks good, quality made, aluminum body, good plast /no melting/, easy work with them. Pins and etc look genuine copper. But one thing - they don´t hold strong enough in RCA socket! Although I gently soldered the metal plates in the connector to make them hold better, since nothing is pressing them against the connector, it is only mediocre, temporary. If your RCA connectors are fat, modern strong, it may work.
