Apple has a history of changing the technological status quo, from digitizing music to making phone screens touch-­sensitive. So when the tech titan announced that its iPhone 7 would not have a 3.5-mm headphone jack, which has been standard on most audio gadgets for decades, it also previewed a compelling alternative. Unlike many of their Bluetooth predecessors, Apple’s AirPods not only have microphones (enabling you to control your phone via Siri) but also can detect when they’re in your ears—­allowing you to automatically pause music, for example, if you pop one out to have a conversation. But their most convenient feature may be automatically pairing with an iPhone, which eliminates the need to dig through settings menus.
