This is the smallest and lightest of all microphone elements. It is also the most effective noise cancelling mic and produces the clearest voice transmission. Diaphram movement, caused by sound waves, translates into an electric signal due to changes in distance between a fixed plate and a charged plate diaphram.
Sound Quality
