Overview
A pool-party guest or picnic planner gets a pocket-friendly JBL speaker with a dust and water rating. Two units can pair for stereo, and Auracast links many compatible speakers wirelessly.
The rating covers poolside and beach use, and pairing options let the sound grow with the group. Recycled materials appear in the grille and the packaging. Power, range and dimensions are left out of the specs.
