True wireless earbuds don't necessarily have to end up as electronic waste when their batteries reach the end of their lifespan. Fairphone demonstrates this with the Fairbuds 2, whose batteries can be easily replaced. The earbuds also offer active noise cancellation and support for Sony LDAC.
I haven’t had that issue fortunately, I use mine to watch video all the time and have had no synchronization issues. Maybe later batches updated the BT modem?
