Homemade earphones were at one time quite useless until a technology student from Ghana developed a broken-down approach to making a functional and durable set of earphones. With some basic electronics parts and tools, you can make your own pair, which is ideal for a school project or quirky gift.
Puncture holes inside the centre of the plastic lids using pliers or sharp scissors. Cut a cable to size and bend it so it conforms to your head. Cut it to adjust to the perfect fit. A strong red cable (about 3 feet) works perfectly to shape and trim down to the desired length.
Thread the wire through the hole in the lids and bend it back so it is tucked inside of the lids. Wrap strong wire around the cable on both ends to hold it in place. Connect the wires to the small round speakers and the earphone pin. You can use the soldering iron to complete this. Be careful to not cause breakage in the wire or melt the lids.
Place the speakers into the lids and cover them with foam. This will make them more comfortable and also more professional looking. Use glue or putty to securely fasten the foam to the lids if you'd like. Take the end of your earphone pin and plug the output/input end into any standard CD player, MP3 player or computer.
