Overview
Hanging from a bag strap or standing in a cupholder, this small speaker plays stereo sound through a dynamic driver over Bluetooth. The strap, USB Type-C cable and speaker come in the box.
A waterproof, dustproof body and a long battery make it easy to take outdoors and into the shower. Hands-free calling adds a little utility. The listing gives modest output and a short Bluetooth range, which suits personal listening.
Who it's for
Outdoor days, pool parties and travel where a pocketable speaker with a strap is enough. Buyers who want deep bass or a big soundstage should look at a larger speaker.
Pros and cons
- Waterproof and dustproof body
- Long battery life per charge

Performance notes
The compact dynamic driver limits bass volume, so the sound suits personal listening. Bluetooth range is quoted in open space and falls with walls. Battery life depends on the volume setting.
