The following project shows a way to convert your earmuffs to headphones with simple some components. Read on to know more on this.
In this, the ditch is used to create noise insulting headphones. This has one black wire, one white wire and 2 red wires which run on either speaker. Some changes are made and the red wire is used as the ground and other two are meant for right and left signals.
By using the volume control knob, the battery can be unscrewed after parting the headphones. The wires which are connected to either sides and running by a cable present on the headband are stripped and can be soldered.
The cable is run by using 3.5 mm stereo plug, which are cut from old ear buds. The left part will be soldered with the other left side of the wire and the other ring get soldered with the right side wire. Now you have the headphone, which can be used in any noisy environment.
