But the headphone jack? It’s on a whole other level than disc drives or ports named after their number of pins. The headphone jack predates not only Apple, but computers themselves. And it is ubiquitous. So, when you’re killing a century-old standard around which the entire audio industry developed, it’s wise to take precautions.Invented for use with telephone switchboards in the late 1800s, the audio jack is among the oldest existing electrical standards. Originally 6.35-millimeter in width, it was reduced to 3.5-millimeter in the ’60s, a transformation that made it pervasive across most every piece of electronic audio equipment you can think of — home stereos, car stereos, camcorders, guitar amps, laptops, airplane entertainment systems, cochlear implants, smartphones, and — until today — the iPhone.Apple is arguing that the future of audio is wireless, that the world’s current assumptions about mobile audio are not only antiquated, but worthy of immediate abandonment. In a world of Spotify and Sonos, it’s tough to disagree. But right now that future comes with a price: You’ve got to leave behind the perfectly good headphones you own and you’ve got to purchase the new wireless ones as an iPhone accessory. It’s up to Apple to make the case that this is a worthwhile exchange.968重庆之声每周一至周五8点56分每天三分钟养成良好英语听说习惯
