zhenyu 10Pcs Brass Insulated Safety Shrouded 4mm Female Banana Plug Jack Socket Solder Cable Connector

Gauge of material is too light for what was expected

I wish I could give it 4.5 Stars because it is almost perfect. As others have said there is no mechanical connection to hold the wire in place so you HAVE to solder the connection. But i disagree with the review that said it would not be a strong connection. I tried to pull off the plug after soldering it and without breaking the wire there is no way it is going to come loose if you did the solder job right. The only issue I had is getting the jackets to completely cover the plug, half of the time there was a ⅛ of an inch that wouldn't be covered completely and it did not seem to matter which color cover, both have this fit issue. I was using them to extend some existing in-wall speaker wire that had factory banana plugs I wanted to keep. I used some shrink tube on each to hold secure the connection so the tiny exposed cover didn't matter in my case. This fits standard audio banana plugs, see photos. I used a Hakko FX-888D at 750 with Kester Leaded Solder 60/40 .031" wire.

The sockets are good quality as are the red and black insulators but... The red ones slip snugly over the sockets and stay in place. The black ones do not. They easily slide on and off so i had to glue them in place.

Easy to use and work well. Just be sure and keep solder off the barrel so that the sleeve slides.

These make really good connections so you can change probes depending on what you need
