A:Answer Hello Jose! Sorry to hear you're having issues with your HYPERBOOM Portable Bluetooth Waterproof Speaker with Big Bass. I would suggest trying to do a Factory Reset of your speaker. To do so, press and hold the Power Button and Play / Pause Button together for 5 seconds, listen for the FACTORY RESET sonification (da-da…da-da – bongo), the speaker will turn off, wait 5 seconds, then Press Power Button to turn on again. If that doesn't help and you're still under your 2-year warranty, I would encourage you to file a warranty claim by following the instructions here: https://support.ultimateears.com/en/limited-hardware-warranty/ - Mathieu from Logitech
