You can record your narrated AirDeck presentations using your computer’s built in microphone. However, your audio might sound a bit like you’re speaking in a wide open room or a tunnel when you listen back to your presentation. We suggest using either a USB or Bluetooth headset instead. One of our favorites is the Sennheiser Culture Series Wideband Headset (SC60-USB-ML). For less than $40, you can have CD quality sound. Your AirPods or other Bluetooth headsets also work really well with AirDeck. Give them a shot and let us know what you think!
