This post will be helpful for those who do not like all those wires hanging all over when they listen to music in their headphones.
First of all, you are going to need a headset…
And an Mp3 player.
Disassemble your Mp3 because you are going to need its card, battery and the front part of the body.
Then disassemble the headphones.
Mind that it does not have a lot of space inside.
Remove some part of the headphone…
Cut off the wire in the headphones and the microphone and solder a piece of wire with a mini-jack on the end.
