The headphone jack is becoming outdated technology in smartphones — that’s what many manufacturers would have you believe. For the convenience of the audiophiles out there, we recently published our list of all phones that have removed the 3.5 mm jack. But what did each company gain inside their flagship phones by removing this supposedly antiquated port?

Starting in early 2016, we’ve seen a trend of removing the 3.5 mm headphone jack in flagship phones, both on Android and iOS. Each company attempted to provide a compelling reason for the removal during their launch events. We wondered, what exactly were the reasons for the removal in each major flagship? Are there any similarities across all OEMs? Perhaps most importantly, do any of these reasons justify the removal of a ubiquitous standard from the phones we use every day?
