Microphones are tools that have several abilities. There are many kinds of microphones with different and special powers owned by different races of the characters in Mermaid Melody.
Microphones are an instrument for converting sound waves into electrical energy variations, which may then be amplified. It can make someone's voice to sound louder or even better if the person has a bad voice. They are invented by humans with great technological knowledge or by special robots in factories.
Mermaid Princesses' Microphones
The microphones that belong to the Mermaid Princesses are called E-Pitches and are made by the power and the energy of the pearls of the mermaids. All the microphones have the ability to cause pain to demons, sometimes more, sometimes less. These microphones have other powers too, but the mermaids have to learn to control their voice to gain more powers. These microphones also give the Mermaid Princesses’ image songs. These are songs that can be sung only by a specific mermaid. The newer the image songs are the more power they have.
Aqua Regina can upgrade the microphones so that they are more effective to the enemies that the princesses are facing, and is able to grant them new and more powerful songs.
Black Beauty Sisters' Microphones
The Black Beauty Sisters' microphones are the ends of their tails. Their microphones have the ability to cause a Mermaid Princess pain. The microphones can be upgraded if Mermaid Princesses' pearls are combined with them. Their song can be so powerful that it can change the mermaids from their idol form back to their mermaid form. In the second season, Mikeru upgraded their microphones and gave them a new song that was more powerful than their previous microphones, without needing a Pearl Tear to empower the mircophones.
Lady Bat's Microphone
Lady Bat's microphone is kind of like a headset. It gives him the ability to hypnotise someone and make people unable to protect themselves. His song is powerful enough to hypnotize a whole audience of a fake magic show to catch the Mermaid Princesses. If his microphone is used in combination with the other Winged Ones, it can cause a Mermaid Princess great pain. His microphone appears when the background music of his song begins.
