The SSM3525BCBZRL is commonly used in various portable electronic devices, including:

1. Mobile phones
2. Tablets
3. Portable media players
4. Bluetooth speakers
5. Gaming consoles
6. Wearable devices

Its compact size, low power consumption, and high-quality audio reproduction make it ideal for these applications.
