Review on 12 Pieces Of GearIT Flex Pin Banana Plugs For Speaker Wire (6 Pairs), 24K Gold Plated Connector Pin Plug Type For Spring-Loaded Speaker Banana Jack Terminals, Supports 12 AWG To 20 AWG Wires by Chris Shepherd

Very nicely machined and sturdy banana plugs. I needed right angle to connect speakers to my receiver in a shallow entertainment center.Unfortunately the jacks are close together and the plugs barely fit.My receiver went into a fault mode the moment I turned up the volume.Turned out the "insulating” sleeve that screws on over the body is metal. There is a coating which scratches pretty easily causing tightly fitted jacks to short the amp outputs.I bought 3/8” heat shrink and used that to insulate the plug body. Guess I’ll throw out the metal covers.I’ve never seen banana plugs covers which weren’t insulating.
