Skunk Juice Earphones - Very Innovatives
The technology sector is not yet ready to allow the ear to completely abandon the use of the wire. A Bluetooth connection is still generate fear in people who have the feeling that those radio waves used for communication, could cause damage whereas the earphones are placed in the head.
Fortunately there are those who can innovate even the wire. Skunk Juice, for example, allow you to use a connector called Zzyzx SnapJack. With two magnets, the section of the connector connects the headphone jack with the headphones.

The results of its use are two: 1) you avoid shoving your head if you pull the thread too, because the magnet detaches and 2) you can listen to the music of other people, equipped with Skunk Juice, simply by attaching the magnet just under their magnet. In this way you can scrounge the music without an MP3 player. Price and availability have not yet communicated.
