⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty should be claimed for manufacturing defects not caused by misuse, such as persistent Bluetooth connection failure after reconfiguration attempts, inability to charge the battery even after trying different cables and power sources, or if one side of the headphones stops producing sound without apparent reason. Issues like structural breakage due to excessive force or accelerated natural wear of components like earpads, when proven to be outside the expected durability standard, may also be evaluated under the seller's warranty and marketplace return policy.
