If, after following all self-help steps and verifying common causes, the sound amplifier exhibits persistent operational failures, such as not turning on even after charging, continuous unintelligible sound, or if the battery does not hold a charge for a reasonable period (less than 4 hours of continuous use), there may be a manufacturing defect. Obvious physical damage caused by misuse is not covered by the warranty. Please refer to the seller's warranty and marketplace return policy for further assistance.
