If you got a notice in the Phorus app (or any DTS Play-Fi app) that your wireless audio product needs a special, one-time update, this is the app that will take care of that for you.

Simply launch the app, it will automatically discover the affected product, and then it will do the rest of the heavy lifting for you. After you’re done, you can close the app. Pretty simple! You’ll still need to do the usual update after this, but the regular Phorus or DTS Play-Fi app will take care of that for you.
