The Jaybird App gives you the ability to customize the sound profile of your X4 earbuds in real time. You can access customized presets created by the Jaybird team as well as many others from Jaybird Athletes. You also have the ability to create your own sound profile and save it by using the custom equalizer. If you think you have created the perfect sound profile, share it with the Jaybird App Community and watch as people from around the world save and use your preset.
Additionally, you can use the Jaybird App to Find Your Buds, Find My Fit, and explore community playlists. The Jaybird App can also enable you to automatically update your product, when updates become available.
