I would say that's correct. It's the quality of the sound from the microphone. Not everybody has a microphone like the one you showed. This is an easy solution that a lot of people can have, and it's easy to standardize, but a proper microphone like the one you demonstrated would probably be sufficient. It's the hearing of our members, not how it gets to them. It's the sound quality.
