Good afternoon deepak_baran,
Welcome to the Apple Support Communities!
It sounds like you are having an issue with Active Noise Cancellation with your AirPods Max, and we'd like to help.
Is this happening only when you are using the AirPods Max for video conferences, or do you experience the same while listening to music or on a phone call? Are you participating in the video conferences on an iPhone or using a computer? What software are you using for these online meetings?
Try adjusting the fit of the AirPods Max to see if that improves the experience.
Make sure the device you are using with the headphones is updated to the most recent operating system.
AirPods Pro and AirPods Max Active Noise Cancellation and Transparency mode
Wearing your AirPods, EarPods, or Beats devices
If the issue persists, please reply to this thread and we'll do our best to help you!
Take care.
