Issue description

 Description:  This is the first training where I've had this experience. I've been in many trainings over the past few years, but this one DO480, has really poor audio quality, and it has nothing to do with my internet or the video settings . If you're using headphones, there's a lot of echo, and during the guided exercises, you can hear the trainer typing on the keyboard every single time, which is very annoying and frustrating. It would be better to invest in a different kind of microphone for the trainer.
