  • In early December 2018, the Malaysian newspaper Sinar Harian reported that a 16-year-old in Rembau, a town south of the capital of Kuala Lumpur, had been found dead by his mother. The teenager, Mohd Aidi Azzhar Zahrin had blood coming from his left ear and had been listening to music through earphones plugged into his charging cell phone. Sinar Harian stated that an autopsy had been performed and had revealed the cause of death to be electrocution. Neither Sinar Harian nor its English-language peer the New Strait Times asserted that the youngster was electrocuted by the earphones he was wearing, but that was the conclusion reached by a number of international publications, including widely-read U.S.-based Vice and Teen Vogue, both of whom aggregated the story. For example, a 9 December 2018 Vice headline read A 16-Year-Old Has Died After Being Electrocuted by His Headphones, with the text of the story stating: Indeed, reports of people dying from being electrocuted by their headphones pop up every so often, but the true causes of these deaths remain unclear. As in the case of Mohd Aidi Azzhar Zahrin, the details from news reports were not specific, and we haven't yet seen clear evidence that his earphones caused the youngster's tragic passing. A Yahoo7! news report contained a purported photograph from the scene (linked here, however we caution it is graphic). A portion of the teen's bloody face can be seen along with an earbud held aloft by a gloved hand, but the earbud appears to be undamaged (save perhaps for a small black mark). The claim that the teenager was electrocuted by the earphones he was wearing rests on a comment offered by district police chief Deputy Superintendent Anuar Bakri Abdul Salam to a local reporter, but the local versions of the story do not maintain it was the teen's earphones specifically that caused the electrocution death. The New Strait Times reported, for example, that: In regards to this story, we consulted a half-dozen emergency room (ER) physicians (members of the advocacy organization American College of Emergency Physicians, or ACEP), and none of them considered it likely that a person could die from an electrical shock received via earphones plugged into a cell phone, although some of them said more details about the incident were needed. None of the reports we found about the incident, for example, specified what kind of phone or earphones the teen had. Los Angeles-area ER doctor Patrick Cichon said that amperage (current flow) is more lethal than voltage (current potential), but both amperage and voltage are below lethal thresholds in typical earphones. Therefore, Dr. Cichon wrote, it would be highly unusual unless using defective equipment or operating outside all normal operating parameters for something like this to occur. Dr. Eric Lavonas, professor of emergency medicine and medical staff president at Denver Health, told us not enough voltage runs through such devices to cause a death as described in the viral news reports. The plug assembly converts high voltage (in Malaysia, 220V wall outlet) into low voltage before it enters the phone. And of course the phone is only putting out low voltage to the headset, he wrote. Detroit physician Brad Uren told us he had seen the story in the wild before we contacted him, and he doubted the veracity of the reporting from get-go. For such a death to occur, he averred, it would require a number of unlikely factors to coalesce into a deadly worst-case scenario. Most phones charge at 5 volts and relatively low amperage, Uren told us via email. Even if a failure occurred at the plug or charger level, that current would then need to travel through the phone and across the headphone plug into the ear pieces. The small circuits in a phone would probably have a hard time carrying significant current to the earpieces, he said, continuing on to state that: As an emergency room doctor, Uren& stopped short of calling the notion impossible because I have seen some strange things in my career thus far, but he added the story that the teen died from being electrocuted by earbuds strains credibility. We reached out to the National Electrical Contractors Association for further information from the electrical engineering aspect of the story, but they told us that not enough details about the incident were publicly available for them to be able to weigh in on the subject.
