⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact customer support for warranty service if the speaker exhibits manufacturing defects not caused by misuse, such as persistent Bluetooth connection failures after troubleshooting, charging port issues preventing charging even with tested cables and power sources, or if the battery fails to charge or hold a charge after a short period of normal use. Issues that arise suddenly without exposure to adverse conditions may also indicate a manufacturing defect.
