AirPod Pro 3--Left Channel Not Working!!

I am on my second set of AirPod Pro 3's. After a day of use, the left channel quit working. I screwed around with Apple support, reset them, etc., and it made no difference. As a result, I exchanged them for a new pair. After using them for a day, the new ones did the same: left channel stopped working.

Presently, I am using my old AirPod Pro 2's with no problem.

After doing some online searches via ChatGPT, this appears to be a common problem. I am returning this set, and will wait it out until they get what I am assuming is a manufacturing defect that possibly is effecting some of the production.

I really liked these, until they malfunctioned.
