The microphone is in spite of its rather low price really very good when it is used correctly.
This means, as I said, first on a good smartphone, its sound must be in itself good.
Second, but also that the user makes sure to be as close as possible to the sound source, because for lavalier microphones are intended. Ideally, she wears the speaker himself, for example, at the tie or the collar of her blouse, because the speaker should not breathe into the microphone, otherwise distortion may occur.
Third, the Aufzeichnnungspegel must be right. This is best achieved when making the user before each use the trouble to readjust the microphone, because it can always come back to other voice and sound volumes also due to various environmental sounds. The best setting is the way manually, automatic will not achieve the same results here.
For the correct setting of the microphone, although this step is carried out after shooting, I also count the noise reduction. This can be very good, but of course, not professionally, made with a free program. Those who want perfect, should buy a matching program, my Vorrezensenten some listed.
Not as good as hoped for, I have to admit, the windshield works. However, one must not expect any miracle for this price, the performance is solid. But please be sure to use the windscreen only where it is necessary, in closed, sheltered spaces he distorts the recording ...
Now I rather used my review for setup and adjustment tips and less said to the microphone itself, which is not even necessary, because with proper equipment and with some (always nötigem) expenditure the microphone works well. It served its purpose, a quality image, comes with good clips and it seems to me to be able to quite live long.
