You will not be able to hear Blue VO!CE World of Warcraft Edition effects through direct monitoring on the microphone itself (headphones plugged into the microphone). However, the signal into your computer will have Blue VO!CE World of Warcraft Edition effects which allow software applications such as Digital Audio Workstation software to include these effects in input monitoring.
To do this, you can adjust your Yeti X World of Warcraft Edition BLEND mode towards the HEADPHONE LED and enable input monitoring on your application.
To test the effects, press the Record button to record your voice. When finished recording press the red Stop button to stop recording. Press the Play button to playback the sound recording, and verify that the voice effect is to your liking.
