4Pcs Banana Plug Jack Female Socket Gold Plated Terminal Binding Post Dual 4mm Banana Plugs Connector for Speaker Amplifier Terminal

nothing with these seems "off". Everything is as it should be. Had no trouble installing speaker wires/banana plugs to it.

Built well

Easy to use.

These would work well for audio projects. I'll be using mine for power supply projects.

Used these in a box I made for my son. Work great

Good quality, these banana plugs do what they were intended to do. Just as good as higher priced plugs.

Very fast delivered.

I've used dual Banana plugs like these for years for building various audio test fixtures and am quite familiar with the better quality ones from brands like Pomona and Keystone. I purchased these knowing they wouldn't be quite up to those standards, but I was disappointed at how cheaply they are made and ended up returning them. The tolerances are fairly wide and the keys that lock the posts in place don't work well. When tightening down the screws, it rotates the side holes in the binding posts. Overall, the parts just fit together too loosely to be functional.
