Airpods

I have airpods 2nd generation with 1st gen charging case, i bought it 2days ago and right headphone just stopped giving a sound until i put it back into the case, but while watching a video it stopped when I was bringing it out so that means it worked but without a sound. So guys should i go to the shop and say that's defect(i have 5 more days for this in this case) or it's because of ios 14 public beta 6 maybe?
Thank you in advance.
test on the Mac or on another iPhone with iOS 13.
If not working, go to the shop for them to test with another iPhone before it is too late for replacement.
