I don't mind looking ghetto, so cut them ends and splice some nice wiring in between and solder the wire tips together then old black insulation tape and happy jamming. Make it a 20 foot LOL
I'm making something nice with cloth wrapped wire and ferrite beads. I'm not sure I'm gonna drop $70 but the $20 connector looks tempting. There goes my dream of making and selling them though, ha! Fancy cable + connectors + shipping = $61... and I still wanted to get ferrite beads, which would probably bring it to like $70 after shipping and etc.
