Blue Icicle XLR to USB Mic Converter/Mic Preamp Review / Test

Today I am testing out another "cheap" microphone interface. This time it is a device by Blue Microphones that is designed for a single microphone; The Blue Icicle.

What's In the Box 

  1. Blue Icicle
  2. 6-Foot USB Cable

Performance / Features

The build quality is not that great. It is a plastic enclosure, and it feels very light. The volume knob is plastic as well, and it is wobbly. 

The design is incredibly simple, on one end is the XLR connector to plug your microphones XLR cable into. The other end has a USB port to connect the device to your computer. On the body is a single knob that controls your microphones input volume, and lastly the word ICICLE lights up when it is connected to the USB port.

The Icicle is listed as providing +48v of phantom power and when measured, I showed +44.4v of power making it through the XLR Cable. This power should be sufficient to power most, if not all, condenser microphones. 


  • Cheap Interface
  • Good sound
  • Low amount of noise
  • Easy to use


  • Cheap build quality
  • No Latency Free Monitoring


This device is pretty cool. It powers condenser microphones and it has a very low amount of noise. The NW-1500 sounded great through it. I don't think you need this if you are just going to be using a dynamic microphone though, I think you would be fine with just a simple XLR to USB Cable. Other than that, this is a nice option for a single XLR Condenser microphone user who wants to record to their computer.

If you have any additional questions about this headset, leave them in the comments on this site or on the youtube channel, and I will try to reply ASAP.
