Leanne, 14, invents headphones that play music and treat ear infections

By Jill Dando News

Leanne Fan’s Finsen headphones is this year’s 3M Young Scientist Challenge winner for an incredible invention.

14-year-old Leanne Fan from San Diego takes the top prize at this year’s 3M Young Scientist Challenge for creating headphones that not only play music but also detect and treat ear infections.

Fan calls them Finsen headphones after Niels Finsen, the scientist who discovered that ultraviolet light can be used to treat bacterial infections — the technology that Fan’s invention is based on.

With 700 million cases of mid-ear infections every year, Fan hopes that this can be an effective and low-cost treatment option for the thousands who are affected. According to Fan, the Finsen headphones could prevent up to 60 percent of hearing loss in children. 

While its infection busting capabilities are impressive, Fan says her headphones are equally impressive at playing music. 

And what does Fan like to listen to on her Finsen headphones? K-pop group BTS.
