Looking for a clear, portable speaker for outdoor Pilates.

Hey everyone, I’m a Pilates instructor and lately I’ve been trying to do more outdoor sessions, sometimes in small parks or even by the beach when I travel. I’m looking for a Bluetooth speaker that’s portable but still has really clear audio so my clients can hear and enjoy.

A few friends have suggested options like the Anker Soundcore and Tribit StormBox Lava. I’ve read some good things especially for clarity and portability but I’d love to hear from people who actually use it.

Does anyone have experience teaching outdoors with these or any other recommendations that balance portability and sound quality?
