Our take

This speaker is a solid choice if you need a durable, water-resistant option for the pool or camping. At forty dollars, it is priced right for a secondary portable speaker that can take a beating without much worry.

Pros

  • Fully waterproof design for outdoor use
  • Supports stereo pairing for dual speaker setup
  • Battery lasts up to 32 hours per charge

Cons

  • Uses older Bluetooth 5.0 connection standard
  • Heavy bass might distort at maximum volume
