⚖️ Seller Warranty & Marketplace Dispute Conciliation

If, after following all self-resolution and verification steps, the product exhibits persistent failures not caused by misuse, such as inability to power on even after full charging, constant noisy audio even at low volume, or Bluetooth connection failure that cannot be resolved by pairing with different devices, there may be a manufacturing defect that justifies activating the warranty according to the seller's warranty and marketplace return policy.
