Wearing earbuds is not a problem. But earbuds contain tiny magnets inside the actual earbuds themselves. While it is extremely unlikely those magnets would be strong enough to cause a problem, it would be best to keep your earbuds at least 6 in (15 cm) away from your device and not to hang them around your neck. Also, keep the charging case for wireless earbuds out of your breast pocket, just to be safe.
