alt Hacker News> It is happening because it works the way that is most useful to most people. The number of people who want to use bluetooth earbuds with a different microphone is line noise in the consumer market.
I don't think you have any idea what you're saying. The scenario I'm describing is when you want to use a bluetooth headset that includes a microphone. Using a different microphone is how you solve the problem.
I have never had a microphone problem with a bluetooth headset. They all always just work until something mechanical breaks through use.
If I had an issue, wired headphones seem a simpler solution than changing the bluetooth standard and more likely to work than wishing manufacturers changed their devices.
