I bought a pair for cabling my Djing setup for live events and parties, they held up trough a lot of being dragged around and a good deal of dirt/liquid and they don't show signs of giving out soon.
-The connectors are made out of a good metal alloy, I stepped on them a couple of times and they did just fine, they feel very secure when plugged in.
-The cable is on the softer side, its a rubbery compound, it allows the cable to be spooled easily and also it doesn't keep the shape at all, this makes setting up live events easier and also it makes everything look tidy.
Bottom line they are worth the money.
