DJI Flip direction track with sound from mobile phone through the DJI app

This was my first ride out having taken with me my DJI Flip and this is the first direction flight attempt. I was quite anxious as I wasn't sure if it would fly over the bushes that were on the side of the road. Sound was recorded through the DJI app on my phone. As you can see the sound is very clear although the phone was in my pocket and the sound of the propellers has been almost completely filtered out.
