This is not true if you have a fairly recent Apple MacBook. The mic quality especially on the Pro models from the last few years is actually pretty good. I often ask people to switch to that mic in our Google Meets if they are using almost any bluetooth headphones (even high end Bose or Sony ones).
My Bose Bluetooth headphones are great except the mic. I think it’s optimized for noise cancellation so it kind of sucks for voice - and for some reason forces noise cancellation to high when using the mic so it’s feels really weird in my ears - even other peoples voices become more tinny somehow
