As smartphones get slimmer and users' expectations for device performance become higher, phone manufacturers are choosing to swap bulky headphone jacks out for something thinner or to omit them completely. How popular is the latter?

At Samsung's Unpacked event this week in New York, the company announced its latest flagship devices – the Galaxy Note 10 and Note 10+ –neither of which have headphone jacks. This is because this type of port takes up a significant amount of space that could otherwise be used for performance-improving internal components or even a larger battery. Essentially, as smartphones become thinner and more advanced, the space taken up by a headphone jack is considered wasted.
