You can use the Bose SoundLink Flex without the app. The app is not necessary for basic functionality of the speaker. The SoundLink Flex has physical buttons on the device itself that allow you to control the volume, play/pause music, and skip tracks. So even without the app, you can still use the speaker to play your music wirelessly via Bluetooth from your phone or other Bluetooth-enabled devices.
However, the Bose app does offer additional features and functionality that can enhance your experience with the SoundLink Flex. The app allows you to personalize your speaker settings, such as adjusting the EQ settings to match your preferences. It also provides firmware updates for the speaker, ensuring that you have the latest features and improvements.
The app also gives you the option to pair multiple Bose speakers together for a multi-room audio experience. This means you can have multiple SoundLink Flex speakers playing the same music simultaneously in different rooms of your house. The app makes it easy to manage and control this multi-room setup.
Additionally, the app provides access to music streaming services, such as Spotify and Amazon Music. This allows you to directly stream music from these services through the app to your SoundLink Flex speaker.
So while the app is not necessary for basic functionality, it does offer a range of additional features and customization options that can enhance your overall experience with the SoundLink Flex. If you choose not to use the app, you will still be able to enjoy the speaker’s core features and wireless connectivity.
