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.
That is true. Fairphone 6 supposedly supports lossless, but with e/os it only goes to regular aptX. I have yet to try it with different phone to see if I can spot difference.
