Bluetooth devices transmit data using short-wavelength radio waves, so they can be physically blocked by objects that get in the way. If you’re getting interference or your audio is skipping, make sure there are no physical obstructions between your speaker and the phone or other device transmitting the sound. Metal and water are especially good at blocking Bluetooth signals, so make sure there are no pipes or electrical wiring between your speaker and source. If you have a specific place you want to use your waterproof speaker, like on the patio or in the pool, make sure you purchase one that will go the distance.
