Well they have value in hearing others and being heard, I'd assume. All my friends have their own mics because we couldn't understand eachother otherwise, and we don't have problems with fidelity. My coworkers are a different story, because consumers rarely listen to integrated microphones before they purchase a device (bluetooth earbuds are absolutely terrible about this, fwiw). Who's at fault, the company for cheaping out, or the consumer for not caring enough to find out if they company cheaped out? The technical problem is solved. The economics problem of getting people to value the solution and marketing problem of educating about it is still open. Regardless, this isn't a problem to be solved by software. It's a consumer electronics problem.
