Goodbye to the 3.5mm headphone jack: The story behind the disappearance of wired headphones from smartphones
The 3.5mm headphone jack has gradually disappeared from most modern smartphones, after major companies like Apple, Samsung, and Google adopted designs that rely on wireless headphones and USB-C ports. The goal was to make devices slimmer and more water-resistant. Apple began removing the jack in 2016 with the launch of the iPhone 7, citing that the port was outdated and that eliminating it allowed for more internal space and improved water resistance. Companies have focused on enhancing wireless connectivity technologies, especially Bluetooth 5, which eliminates the need for wired headphones. Additionally, using USB-C for data and audio transfer has become more popular, particularly after the European Union mandated a universal charging port to reduce electronic waste. Despite this shift, some users still prefer wired headphones for better sound quality and greater stability. While some phones still retain the 3.5mm port, the overall trend is moving toward a complete reliance on wireless technologies.
