Incident Overview

The following morning, when the consumer picked up the headphones, they burned their hand on the charging port. The port was hot enough to cause immediate pain and a visible burn injury to the consumer's index finger. Melted plastic from the headphones transferred to the consumer's finger and palm. Inspection revealed extensive thermal damage: the plastic surrounding the USB-C port had melted and warped, and the port opening was deformed. A second device charging on the same adapter showed no overheating, and the adapter and cable were undamaged. The consumer stated that all evidence points to the thermal event originating inside the headphones, and noted that this is a documented, recurring safety issue across multiple Sony headphone models.

Safety Concerns

Immediate Dangers: The primary danger is a burn injury to the user's skin from contact with the overheated charging port. The report describes a visible burn and melted plastic transfer, indicating temperatures high enough to cause tissue damage and plastic deformation. Users handling the headphones during or after charging risk similar burns.

Long-Term Risks: Repeated overheating events could degrade the internal components of the headphones, potentially leading to electrical shorts or fire. The melted plastic around the port suggests a failure of the insulating materials, which may increase the risk of electrical arcing or thermal runaway in future charging cycles.

Who Might Be Affected: The user is directly at risk of burn injury. Because the overheating occurs during charging, the headphones may be unattended (e.g., overnight), increasing the potential for fire if the thermal event escalates. Bystanders in the same room could be exposed to smoke, fire, or burns if the product ignites nearby materials.

Warning Signs: The incident occurred without prior warning; the consumer reported no unusual heat or behavior before the event. However, any unusual warmth, discoloration, or odor from the charging port during or after charging could indicate an impending failure. Users should inspect the charging port regularly for signs of melting, warping, or discoloration.
