How to make an adapter
Before to make any adapter, make sure the device and accessories do electrically compatible, and nothing but plugs, no different.
If you need to connect headphones or microphone equipped with a 3.5 mm Jack to 6.3 mm socket, or Vice versa, for the manufacture of the adapterand take the plug diameter coinciding with the diameter of the socket on the machine and the socket, the diameter of which coincides with the diameter of the plug on the headphones and the microphone. Connect the corresponding contacts (three). If either on the plug or on the socket, either on and not the other three pins, and two, that their adapters only for MIC but not for earphones. Such connectors United by a common and Central contacts. To connect a two-pin plug to the headphone Jack is impossible, because output short circuit one of the channels, which will arise in this case, it is possible to bring the apparatus down.

Find out if you need to connect the contacts of the same name, or, say, to apply the output signal from the unit to the input pin of the accessory, or Vice versa. Make the corresponding connections on the second parts.
Do not allow in the Assembly of short circuits. Place the adapter in a solid insulating housing. Before making any connections, switch off the device and accessory, unless otherwise expressly permitted by the user manual.
