On a film set I would expect anyone in ear protection like that to use the kind with either external sound amplification (mic on the outside, speaker on the inside, so they are headphones) and/or with wireless audio transmission (bluetooth/etc, speaker on the inside, so still headphones)

Should still not be called headphones when their primary function is hearing protection.
