Why do you call miniature Omnidirectional mics “Binaural microphones” Are you trying to confuse people?
No, but all of this can be quite confusing. The reason mini omni mics are sometimes called binaurals is that over the years, in the industry, these little omni mics have simply become known as “Binaurals”. Really, what they would be more accurately called is “dual channel miniature omnidirectional microphones that are capable of making binaural or stereo recordings”, but we might grow old having to say that each time, so we just shorten it to “binaurals”.
