    Where there is sound, there is SINOBAND!

    The biggest and NO.1 problem is its waterproof grade, it has only been graded for IPX5, not some of you expecting IPX6 or IPX7. That is to say, the S400S cannot be fully immersed into water, if you have strictly high standard of using it in such demanding waterproof situations, then this speaker is unfortunately not for you. Other than that, if you just use it for camping, hiking, outdoor sports, or taking a shower in your bathroom, or for office and home or leisure use, then it is 100% a good fit for every penny you pay.

    For the sound reproduction, our speaker stand out from other competitors. We encourage you to compare our S400S with other 10W indoor & outdoor waterproof or non waterproof portable Bluetooth speakers, either no name or big name brand manufacturers, and we believe that this process will enhance your appreciation of our product S400S you select. Hear the BASS, and the overall balance of the tuned sound, not just compare the harsh high tones.

    For battery capacity, we know exactly every minute counts when you're in outdoor activities, for music, for charging, for urgent phone talk, even for emergencies, etc. The long lasting battery pack is just right here for use, protecting from any loss you might suffer from the loss of power. Not 1800MAH, nor 4000MAH, or even 5200MAH, we give you the FULL and REAL 7000MAH battery pack for fuel.

    Battery status checking indicator. There are 4 led light bars to show the battery status, 25%, 50%, 75%, 100%, it is highly important to remind you when to stop, and for more important tasks to do or even charge the S400S.
