I use these a lot! A tad bit more trouble to use that the crimp kind but way more secure & nest looking too. Sometime I’ll slide a heat shrink sleeve over when I’m done just for extra peace of mind.

great help for soldering the pigtail to the shielded cable

I am building an experimental. Just found these little sleeves and I think a great invention to assist in wiring the headphone jacks. adding the pigtails for grounding the tefzel shield

They work great, but do take quite a bit of heat to get the solder to melt.

Very necessary and they work but way too expensive
