Topic: What kind of cable end is this?

[George]

So I thought this plug was "banana terminated cable," apparently its not.  What the heck is it?  This is what I'm currently using and silly me, I purchased a pair of banana terminated cables for a center channel I'm planning on buying, turned out to be the wrong cables (woops).  These are the ones I accidentally purchased:

Any help would be greatly appreciated.  I'm going in circles on google at the moment, hence the reason why I posted here.

I think I figured it out, apparently there's different types of banana plugs.  I'll contact the vendor to set up a return.
