★Like the video? Subscribe! br The Blue Spark is finally here and ready to be unboxed!! This is the Blue Spark microphone by Blue Microphones! The Blue Spark is an XLR Condenser mic that needs an audio mixer andor preamp to function. I've been using this mic since I have recorded the unboxing and I will say, this thing sounds great, has a great sound presence, and is fairly focused and doesn't pick up too much of my overly loud computer haha.
