What headphones do not get tangled up in knots

Murphy's Law is under a scientific basis - the conclusion made by the California Institute of Physics, 3415 studied the entanglement of headphones. It is known, one has only to put the wires from the player in a pocket or bag, in a minute they turn into a ball of knots. Scientists for the purity of the experiment was shaken headphones in a special box. The study found that the wires without help themselves able to tie in the 120 node types. And rather complex knots formed in a few seconds of shaking.

Authors Look At Me set less ambitious, but no less useful experiment: during the day wore their bags and backpacks different headphones to see how much they get confused. During the experiment, it was found that the number of nodes depends on the model. For example, headphones Bowers & Wilkins C5 are the most comfortable in this regard - they turned out to be just 21 knots. And the model Bose SIE2i Sport Headphones nodes were as many as 50.

Enriching humanity this invaluable wealth of knowledge, experimenters, probably because of modesty, silent on how to address the problem of tangled headphones. For its part, we note that the simplest and most effective way to solve the complicated story: cord folded in half, then half again, and then tie it in a simple knot rather weak.
