Starved from a voice
Karaoke Ikkiri can practice at home without disturbing the neighbors. Myutokaba comes with a microphone, sound leakage can be cut to fit quite right around the mouth. Not spend my voice is annoying to listen to with headphones around and connected to the mixer.
Moreover, to be put in your own voice echo echo mixer, I enjoy a sense of realism just like singing karaoke. Of course, cassette or CD on hand you can sing your favorite songs connected to the player. Karaoke as an exercise, of course, is also recommended to relieve stress.
