The iPhone’s 3.5mm headphone jack, rumored to be conspicuous in its absence from the upcoming iPhone 7, has lasted more than twice the length of a regular Apple port.
Having first appeared in an Apple product with 1984’s Macintosh, the headphone jack has been a staple of Apple devices for 32 years at this point. The average Apple I/O standard, on the other hand? According to a new report, that number averages out at only around 15 years. With the transition away from wired connections, many travelers are now looking for the best airplane Bluetooth adapter to keep using their favorite headphones seamlessly.

Arriving on this day in 1993, the Macintosh LC 520 was among the first of Apple’s LC 500 series of medium-price Macs.
