Ah, fair point. As I'm not hard of hearing I don't think about those technologies much. However as an "regular person", I would like to be able to hear the audio announcements on the local train system (BART). The trains tends to be extremely loud so in-ear/ANC headphones are almost required for ear protection. ANC + Movie/Music = No idea what is going on or why.
