I purchased these to keep my wires from shorting out when plugged into the speakers. They work great for it. There are a couple of things I wish these had different. I wish the prong was shorter as it sticks out and threatens to fall out while it's in the slot. also, I needed to use electrical tape over one of the ends as the holes in the speakers were very close together. After that, everything works great.
I purchased a few pairs of these to complement the Premium speaker system I purchased on here as well, which do not accept banana plugs. The crimp type connectors are so much better and are very easy to secure with a small screwdriver. A good value and they appear well constructed.
