The answer to all these problems is very simple. You only need to understand a little of the aspirations of the fairies who inhabit these assorted audio, audio-visual, computer and analogous cables. They, along with the fairies inhabiting wire coathangers and hosepipes, dream of becoming a Christmas tree lights fairy. Now you're talking tangles!
All these little barbs, hooks, clamps and clips to make the tangle impossible to untangle!

The solution is expensive! You must buy the fairy occupying each cable their very own set of Christmas tree lights and they will immediately desert their existing home and move in. You obviously cannot use the several tangled sets of lights, lying in boxes on top of cupboards, reminders of the times you have given up and bought a new set – they are already occupied!

The problem is, you now have these wonderful cables, each one straight as a die and untangled, which provide desirable residences for all the homeless fairies! Back to buying more Christmas lights!

I regret my solution is only temporary.
