From Richard, Owner of Prompt-it®:

We have received many enquiries about audio over the last year and it was about time we offered a simple, effective solution to our customers. We came across this little microphone a few weeks ago during one of our video productions and immediately thought: “This is PERFECT to offer for Prompt-it®”. One solution, easy.

How it works (the basics):

  • Find the ‘mic’ plug on your camera. Plug the microphone’s jack into it.
  • Unwind the long cable (4 meters), run it from your smartphone, along the floor, up to your belt, then under your shirt or jacket, and clip it to your jacket’s lapel or t-shirt collar. Do the same for the other person.
  • Start recording! Don’t forget to do a clap before start talking or interviewing. Great help with the syncronising of video and audio in editing process.

The (confusing) specifics of this microphone:

  • Its omnidirectional condenser capsule captures the sound equally from all sides of the microphone. This design lends to effective, hands-free recording of speeches, interviews, dictations and more.
  • It uses a TRRS connector to connect into your smartphone or tablet’s headphone input.
  • And With 4m (13′) Cable, the BOYA BY-LM300 can be used for presentations, podcasts, webcasts, or any situation where more than one subject needs to be recorded.
  • The package comes with mic clip and foam pop shield each two pieces and a carry pouch.
