REVIEW – About 3 years ago I created the 247 Real Talk podcast. As my audience has grown I have been able to expand into a network TV group and continue to look for ways to grow and create/deliver more content. I was recently introduced to Blast Radio and a device called the Blast Mic that allows live streaming on the go through the Blast Radio app to their audience. So I’m going to test this Blast Mic now to see if it can help me with content creation and my versatility.

What is it?

design and functions

The Blast Mic consists of an external plastic case and a mesh on top to cover/protect the mics. The ports and buttons are on the edges and there is a 1/4-20 inch bracket on the bottom edge. Under the flat front of the case is an LED display that provides a status indication.


After charging the Blast Mic, the next step is to install the Blast Radio app (iOS/Android) and create an account. Next, turn on the Blast Mic with a long press of the red button, which will put it into setup mode. Next, follow the app to connect and prepare it for streaming.


Once the Blast mic and app are set up, you can go live with a press of the red button:

After using the Blast Mic a few times, I managed to find the ideal distance from my mouth to prevent cracking. I still think it needs a windscreen/popscreen, but you can listen to an episode and hear the quality from the following link:

What I like

  • The concept
  • The built-in ports of such a small device allow you to poll guests
  • The simple live streaming ability
  • The quality of the recording once you get the right distance to make sure there is no popping
  • The app is nice and the community seems nice
  • The ability to monetize something through the app

What I would change

  • It’s not an attractive or tech-savvy device
  • I couldn’t find a way to set up a device without using 2 devices for the setup process (see video). Update: I was finally able to set up the Blast Mic with a phone and the hotspot on the same phone. Not sure why it wouldn’t work after trying multiple times at first.
  • It does not come with a windscreen/pop filter, so popping noise may occur
  • When charging with the Blast Mic off, there is no visible charge indicator to show when the battery is fully charged. You have to turn it on to find out
  • Offer a plan at a reasonable cost to keep recordings and thus create a publicly accessible archive within the Blast radio platform without having to move them to a new host. Recordings currently “disappear” publicly after 24 hours. They can still be downloaded and used elsewhere.
  • The quality of the file of your recording, which you can download for further use, leaves a lot to be desired

Final Thoughts

The Blast Mic is a really handy device for the podcaster or broadcaster on the go. It offers a good amount of connectivity that makes it very flexible and adaptable. Additionally, the audio produced is clear and frankly easy to set up and use. If you want to make your recordings publicly available on an ongoing basis, you must download and upload them to a more permanent host within 24 hours. Also, the Blast Mic is a bit ugly for what it is, in my opinion. While this has nothing to do with functionality, I want something sleek and professional looking so that when I’m using it in a professional setting, that’s what I look like. Still well done.
