How many times has this happened to you - you are in the middle of a fantastic song on your earphones and for some reason your one ear has turned deaf.
Of course, it is not your ear but your earphones that are creating the effect of the temporary muteness.
Your analytical mind gets into action to find the specific cause of the earphones not working. It is like being in a dream all gone wrong - instead of pinching yourself to check if you are awake, you start pinching the earphones at various places to check what the cause of the problem is. Is it the point where it connects to the device, or the place where it branches off into two wires or right at the end where the confluence of the earphones with your ears happens.
Immediately after identifying the cause, you try your skills at geo-positioning that part of the phones. Various angles and positions are tried until that one in a million position is conquered.
And you emerge with a sense of great achievement. And a notion of happiness that you don't need to send it for repair...
Only till the person sitting next to you knocks you on your shoulder to check on what song you are listening to. And then the whole process starts again...
The problem also manifests itself when you connect your phone charger to your phone. Similar techniques are followed there as well.
