If you want the freedom wireless headphones allow but have only standard wired headphones, you may not know that it's possible to convert them to wireless. This process requires just a few tools and materials but can save you money by not having to buy new headphones.
Unplug your headphones from any electronic device they may be connected to and remove the cushion from one end of the headphones (if your headphones have speaker cushions).

Remove the screws on the plate covering the speaker. Locate the two headphone wires inside the earphone.
Remove the screws from the plastic housing of your small FM radio, and remove the motherboard assembly from the housing.
Strip about an inch of sheath off of the headphone wires with the wire cutters. Be careful to cut only the sheath and not the actual wires.
Solder the ends of both headphone wires to the terminal on the radio motherboard marked "Stereo Output."
Place the motherboard assembly inside the headphone. The radio batteries will be connected to the motherboard, so make sure there is room to place them inside the headphone. Tape or glue the assembly to the inside of the headphone and replace the headphone plate, screws and cushion.
Cut holes in the side of the headphone to account for volume and other knobs connected to the assembly.
Plug your FM transmitter jack into the port in your MP3 player and turn it on. Use the frequency knob on the motherboard assembly of the radio to set it to the frequency on the transmitter. The headphones will now be connected to the MP3 player or audio device.
