What is the worst thing that can happen to a pair of headphones you are using with a mobile device? Well, duh, it's to have the wires connected between each of the ear buds get tangled. Besides being a pain in the behind to untangle (and always to have to do at the most inopportune time), there is the real chance you will pull too hard and end up breaking the speaker off of the wire. Or bending it to the point where it accomplishes the same thing. What are needed are two things: 1) a pair of headphones to use with a mobile device that does not get tangled, and 2) a reasonable cost for these headphones so you are not putting yourself out. Both get accomplished with the cord cruncher
