Отзыв о Микронаушник Mxmedia Black Magnet магнитный с выходным микрофоном и кнопкой-пищалкой. от Adam Gontarz ᠌

Lousy quality textolite on the output microphone, in general, I would make this microphone removable so that it would be possible to stick it in different lengths, you need one button but it is conveniently pressed, as practice shows in exam conditions, more than one button just interferes, a better-thought-out binary signal system For the dealer: if the teacher knows how it works and intends to ask for understanding, the earpiece will not help In my opinion, this method is good only if you need to memorize a lot precisely in terms of volume, when just remembering that the proof of the theorem from the contrary is not enough, and you need to learn a lot. Yes, a neat person can record a written exam under dictation, but they usually follow such things. Also remember that the person on the other end must also know the material, otherwise there will be problems with things that are difficult to pronounce, they will dictate too much and forget about the main thing. fastened to a sweatshirt and not to the arm with elastic bands, fewer trenches will be burned by rolling up the sleeve.
