Taotronics 53 Bluetooth Earbuds Won’t Connect After 3 Years

I’ve had my Taotronics 53 Bluetooth earbuds for three years, and they’ve always worked perfectly. However, recently they stopped connecting to my devices no matter what I try. I’ve reset them, checked the settings, and followed troubleshooting videos, but nothing seems to work. Is this a common issue after a few years of use? Could it be a problem with the Bluetooth version or some kind of chronic defect? I need help understanding if there’s a solution or if the earbuds have just reached the end of their lifespan. I’m really disappointed and hope Taotronics can provide some guidance to resolve this issue.
