There are still incompatibility issues in practice. And even still, you will get something that won't outlast the inbuilt batteries - which makes it absurd to spend money on them. I still use, on a daily basis, my $300 headphones that are a decade old. I can't find any bluetooth headphones fort $3-400 with NC that matches them. And they won't last a decade for sure (whereas my wired ones probably will last several).
