Branded good quality microphones are really costly and for startup Youtubers it is not an absolute necessity. However, for recording conversations, small collar microphones can help you a lot by recording closer voices only; while your camera’s built-in-microphone records all available sound around.
So, here is a little guide to create a good quality collar microphone yourself at home. I made one with the help of my friend Mr. Jijukumar. All you need is:
- Condensor Microphone unit from local electronics store ($ 1)
- 2 metres of shielded wire ($ 1)
- 3.5 mm audio jack (Android type 4 leads)
- Pliers, soldering iron
- Cap of a pen with clip

All you have to do is to connect the wire to the condenser microphone by soldering 2 wires in the shield wire. Remember short leg of condenser Mic is the negative one and should be soldered to the shield cable or black wire. Use any colored wire for the longer leg.
After soldering the microphone end, insert it wholly into the pen holder and let the wire out through a hole. The other end of the wire should be connected to the audio jack by soldering. For using with Android phones, the connection should be as given in the image below. Make sure that you have inserted the wire through the jack cover, before doing the soldering work.
Once it is soldered, your microphone is ready to use. Push it into your phone’s earphone socket and record videos with your phone camera. Some phones may display a message showing that audio is recorded through the external microphone. Compare the audio quality of your microphone with the built-in-microphone of your phone.
