These GAOFEI GF-F025R connectors have a very good manufacturing quality. They have 24K gold-plated copper alloy conductors to ensure excellent conductivity and very good resistance to oxidation. Similarly, the connector bodies are also made of copper alloy. They also have Fluoropolymer insulation, which limits interference that could alter the audio signal and degrade sound reproduction. Finally, the design of these connectors is both sober and particularly elegant, allowing you to create connectors that are both powerful and aesthetic.
