The BBC are on of the most trusted news sources on the planet, Â so when stories fly around about the next iphone dropping it's 3.5mm jack plug and moving to using their own lightning port or bluetooth. We think this is one of the usual stories that flies around before they release any new apple product, but when the BBC picks it up we take note! and this brilliant article shows that the common 3.5mm jack plug has a more of a history than we knew.
After rumours that Apple was going to get rid of the headphone jack in its imminent iPhone 7, more than 200,000 people have signed a petition asking them to reconsider. This humble plug is a rare example of technology that has stood the test of time, writes Chris Stokel-Walker.
For what remains an unconfirmed rumour, a lot of people are upset about the new iPhone. It's alleged that Apple will be scrapping the 3.5mm socket, instead leaving headphones to be plugged into the "Lightning" port - the company's own design of socket.
Cynics have pointed out that while this might enable iPhones to be slightly thinner, it will render many headphones useless and force manufacturers to pay Apple a fee to use their Lightning plugs on products.
The petition says Apple's purported move would "singlehandedly create mountains of electronic waste".

Initially the quarter-inch jack was used by operators in old-fashioned telephone switchboards, plugging and unplugging connections. "The standard has always been quarter-inch jacks," says Dr Simon Hall, head of music technology at Birmingham City University.

The 3.5mm version quickly became popular, spread by the use of personal headsets on transistor radios in the middle of the 20th Century.
The jack is known as a tip, ring, sleeve - or TRS - connection. The "tip" transfers audio into the left-hand earplug of a stereo headphone set, and the "ring" the right. The "sleeve" is the ground or "shield". This set-up is stereo - the original mono plugs had only tip and sleeve. Certain modern plugs have a second ring to allow control of a headset microphone or volume.

Apple has a track record of being early to abolish things which then start to disappear from rival products too. It killed the 3.5 inch floppy disk early. It also was among the first to remove optical drives.
But those signing the petition on the Sum of Us site and social media users have suggested that Apple's motive is greed.

If you're using £1,000 headphones with your iPhone at the moment, you're going to be slightly cross.
And Charlie Slee thinks consumers are also concerned about ceding control to Apple. "People are mainly upset because they like to think they're in control of their technology," he says.
But this sense of the consumer in control is misplaced, Slee says. "Actually, the contrary is true: The big technology companies have always been in control of how you listen to music and watch videos."
The headphones in history
Image copyrightGetty Images Headphones are really just ordinary telephone receivers adapted to fit a headset, says John Liffen, Curator of Communications at the Science Museum. The headset usually had just one receiver for a single ear.
The first headsets with a receiver for each ear were just called "telephones". The name was supplanted by "headphones" by the beginning of the 1920s when they were being widely used to listen to broadcasting via crystal sets.
For many years headphone receivers were the simple "Bell" type with permanent magnet, coil and diaphragm. Today's high-end 'phones are considerably more sophisticated, similar to miniature loudspeakers.

"I think it's a storm in a teacup," adds Simon Hall. His reasoning? Having a standardised headphone jack on mobile phones and MP3 players is only a relatively recent luxury.
"If you look at the previous generation of phones, things like Nokia phones, you had to have an adapter," he reasons. "If you want to connect headphones to professional equipment, you also need a professional adapter."
As recently as 2010, Samsung phones came equipped with a proprietary headphone port not dissimilar to Apple's rumoured replacement for the 3.5mm socket, the "Lightning" port.
This isn't the first time Apple has aroused ire. Way back in 2007, with the first iPhone, it received complaints that the headphone jack was sunk into the casing.
One technology wag called it "a great business plan - break an important device function, and sell the solution for fun and profit." The problem was fixed when Apple released its second iPhone model in 2008.
But Apple is known for evolving technology: "They got rid of DVDs, they got rid of the floppy disk drive; they got rid of parallel ports, they're eventually getting rid of USB. This is how they move," says Dediu, the Apple-watcher. He reckons the switch to Apple's proprietary connection augurs a planned move to headphones that are akin to the Apple Watch.
Image copyrightGetty Images Dediu forecasts a rapid change. "What Apple does is catalyse transitions," he says. "It would have happened anyway, but if it wasn't for Apple it'd have taken 10-15 years, but now it'll happen in 5-7 years."
That the time may have come for the 3.5mm jack to be replaced shouldn't come as such a shock, believes Dediu. "Studying Moore's Law and the history of technology, it's clear we're not going to stick around with something analogue for long," he says. "It's almost puzzling that it's taken so long."
