How to use

To begin using the speaker, ensure it is fully charged using the provided interface.

Once paired, you can control playback and manage calls directly through the speaker's interface. For magnetic mounting, attach the included ring to your desired surface or device to secure the speaker in place.

What to consider before purchase

Check compatibility with your specific device's Bluetooth version
Consider the battery life, which varies based on volume levels
Verify if the magnetic mounting surface is suitable for your intended use
Assess if a single unit meets your volume requirements or if a second unit is needed for stereo pairing

Usage recommendations

For optimal battery performance, it is recommended to charge the device fully before the first use.
