Is there an app for Project Rock headphones?
You should absolutely download the My JBL Headphones app (this review used version 5.1. 2). While Project Rock has the majority of its features available at the press of a button (particularly if you use voice assistants), important features like firmware updates and custom EQ reside in the app.
How do I turn up the volume on my under Armour headphones?
You can control the volume by pressing the volume + and volume – buttons located on the back RIGHT ear cup.
