That story looks bogus. Snopes [1] says:

> 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.

...

> 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.”

Here's a high profile case from Australia a few years ago.
