Airpods Pro (R) tic tac tic tac sound

I bought Airpods pro in March 20 and just before few weeks , I found the right Airpods pro is producing a sound like a tiny part is broken inside and when I shake my head, Drive on rough road and even in flight(when turbulence), it is producing very erratic clicking sound and very prominent. I am in India and when visited authorised service centre, they said to leave the airpods pro at them and I couldn’t as I had to travel another city. The problem is only in ANC mode or transparency mode On. Hope apple ll fix the issue as it was not there earlier or else I ll pay a visit to service guys.
