How to use: First, adjust the headset to one of the 3 available sizes to fit your head comfortably. Then, move the microphone to the right position. To use NARIKIRI mode, just turn it on and watch the LEDs on the headphones and microphone light up in a pattern. For LIVE mode, switch to it and see the level meter change according to the surrounding noise. Things to note: Remember, this is for cosplay and not a functional headphone or microphone. Maintenance: Keep it in a dry place when not in use. Avoid dropping it or exposing it to extreme temperatures.
