What’s the Difference Between Globluum SU3, SU5, SU7, and SU9? How to Choose the Right One?

Why Choose a Globluum MP3 Player?

The Globluum SU Series is not simply a lineup of four MP3 players with different storage capacities. Instead, the four models are designed around different usage needs, with two distinct system experiences.

SU3 / SU5 focus on simplicity, distraction-free listening, and child-friendly use.

SU7 / SU9 feature an open Android system, allowing users to install compatible third-party apps based on their needs.

No matter which model you choose, you can store music, stories, and audiobooks directly on the device and enjoy offline playback without Wi-Fi.

Globluum SU3, SU5, SU7, and SU9 have a similar appearance, but there are important differences in their operating systems, RAM, storage configuration, and app installation permissions.

3. What’s the Difference Between the Operating Systems?

This is one of the most important differences between the four models.

Closed System — SU3 / SU5

SU3 and SU5 use a closed app system, which limits the installation of third-party apps. Only apps permitted by the system can be installed, such as Sound+, JBL, YouTube, Shazam, Sonos, and other supported applications.

This design helps reduce unnecessary apps and notification distractions, allowing children to stay more focused on music and audio content.

Best for:

“A dedicated music player for my child, rather than a phone with complicated features.”

Open Android System — SU7 / SU9

SU7 and SU9 use an open Android system and support installing compatible third-party apps through Google Play, including learning apps such as TT Rockstars and NumBots.

Users can expand the functionality of the device based on their needs, making it suitable not only for music but also for learning, reading, and other everyday activities.

App Compatibility Reminder

SU7 and SU9 are best suited for everyday apps related to music, learning, reading, and similar activities.

For large games or apps that require higher hardware performance, we recommend checking the app’s compatibility with the device’s Android version, hardware configuration, and Google Play before installation to ensure a better user experience.
