I was eagerly waiting for Airpods 3 launch and ordered them via Apple Store online when released which are made in china. For very few days use I did not feel comfortable even the sound quality was very flat as well my ears pained like ****. Returned them and I have ordered new pair in amazon recently just to give another try and the airpods I received which are made in vietnam. I feel way comfortable and no ear pain even after long time usage. even the sound quality is way better than made in china airpods 3. I was surprised what would be the changes made in vietnam airpods 3. I am finally happy and enjoying using them every day.
