Saving-water speaker is a waterproof blue tooth speaker for music-lovers who wants to have a better experience when taking a shower. The best part of the speaker is that it utilizes the power of the water flow to adjust the volume. When users choose the saving-water or normal mode, the music would sounds moderate and soft, when the shower takes too much water flow, the volume would be louder or even harsh. The speaker reminds people of the importance of saving water in such a natural way.
