⚠️ Important: To unlock the full potential of your Soundcore headset or headphones, you must download the Soundcore app on    your smartphone (Android or iOS). The app allows you to access and customize EQ settings (including preset sound profiles where supported), adjust audio preferences, receive firmware updates when available, and manage supported features for a more personalized listening experience. Without the app, the device will function normally via Bluetooth, but advanced customization and feature controls may be limited.
