Magnetic Attachment and Phone Stand Functionality
The speaker features a magnetic base for convenient attachment to metallic surfaces. An included magnetic ring allows you to attach the speaker to non-magnetic surfaces or directly to your phone to use it as a stand.
- Attaching to Magnetic Surfaces: Simply place the speaker's magnetic base against any suitable metallic surface (e.g., refrigerator, desk leg).
- Using the Magnetic Ring: For non-magnetic phones or surfaces, peel off the adhesive backing from the magnetic ring and firmly attach it to the desired location. The speaker can then be magnetically attached to this ring.
- Phone Stand: When attached to your phone, the speaker can prop it up for viewing in both landscape and portrait orientations.

Waterproof and Dustproof Use
The IPX7 rating means the speaker can be submerged in water up to 1 meter (3.3 feet) for 30 minutes without damage. The IP6X dustproof rating protects against dust ingress. This makes it suitable for use in bathrooms, by pools, at the beach, or during outdoor activities.
