Review on JS-919 Amplifier Terminal Connector Binding Post Banana Plug Jack Mount (20Pcs) by Dave Hammon

Binding posts are supposed to have a hole drilled through the post so that a wire can be inserted through the hole. These posts do not have that hole, and so are unsuited for many applications. If you are going to use banana plugs or fork connectors instead of bare wire, these will work fine. If you want to use unterminated wire, you will want to look into a different product or plan on drilling through the posts yourself.
