Speaker pins can be used instead of banana plugs to manually install speaker wires across a HiFi speaker system. They offer some protection for the connection while also making installation much more accessible.
Speaker pins are a smaller variant of banana plugs, and they have a lot of the exact origins. They lack the spring contact found in banana plugs. Instead, speaker pins are only used with binding posts that include a hole in the centre through which the pin plug can pass.
Banana plugs are connectors that only connect one circuit, and the plug's spring-sided construction maintains solid contact even after multiple connections. They are usually attached to binding posts, and they create a firm electrical contact that may carry much electricity when used with speakers.
