With the My JBL Headphones app, we’re able to provide our users with the unique experience of having individual hearing preferences enhanced by their JBL headphones, using Personi-Fi technology. We cooperated with 4 famous DJs, measured their hearing preferences, and transferred these takeaways to our users. People can dive into the DJs' personal hearing preferences themselves as well as creating their own. Besides that, our users can choose their favorite voice assistant to talk to, while selecting a smart ambient mode for listening in specific environments.
