to be unveiled on September 7th in San

The co-founder of Apple has warned the iPhone maker not to kill off the headphone socket in its upcoming model.

Steve Wozniak said a lot of customers will be frustrated if Apple removes the headphone jack - and claimed wireless headphone simply aren't good enough.

'If it's missing the 3.5 mm earphone jack, that's going to tick off a lot of people,' Wozniak told The Australian Financial Review.

Steve Wozniak said a lot of customers will be frustrated if Apple removes the headphone jack - and claimed wireless headphone simply aren't good enough.

WHY WOULD APPLE DITCH THE HEADPHONE JACK? Getting rid of the headphone jack would help Apple shrink the iPhone 7's thickness considerably. Its latest smartphone, the Phone 6s, is 7.1 mm (0.27) thick but removing the 3.5mm jack could drop this by a further by one mm (0.04 in). Such a shift would also mean larger, stereo headphones using an internal battery would be able to draw power directly from the iPhone - or other devices, if the change is enforced across the Apple board. Elsewhere, Lightning-based headphones would experience less 'crosstalk', or signal interference. Advertisement

'I would not use Bluetooth … I don't like wireless.

'I have cars where you can plug in the music, or go through Bluetooth, and Bluetooth just sounds so flat for the same music.'

Android handsets use a wireless standard called AptX, which has better quality - but Apple has not backed it yet.

Wozniak said he expects people will still be able to connect wired headphones into the lightning port of the iPhone, but they will have to have an adapter.

'Mine have custom ear implants, they fit in so comfortably, I can sleep on them and everything.

'And they only come out with one kind of jack, so I'll have to go through the adapter,' he said.

'But we'll see. Apple is good at moving towards the future, and I like to follow that.'

According to a Bloomberg source, the next-generation versions of the iPhone are due to debut on September 7.

This information coincides with news from last month that pre-orders for the new handsets will begin on September 9.

Speaking to Bloomberg about the MacBook Pros, a source said these laptops 'aren't likely to debut at an event currently scheduled for September 7 to introduce next-generation versions of the iPhone'.

Forbes was the first to spot this leaked information from Mark Gurman, who has made a name for himself with accurate Apple leaks for 9to5Mac and is now a journalist for Bloomberg.

This comes just a month after Evan Blass tweeted Apple owners should get ready to place their pre-orders on September 9.

WHAT WE KNOW ABOUT THE IPHONE 7 According to Bloomberg, next month's iPhone will be equip with a dual-camera system capable of capturing brighter photos with more detail and cameras that can merge two images into one. Users will also have to throw out their white iconic headphones, as there will not be a headphone jack - sources say it will be replaced by a second speaker. Another rumor regarding Apple's much-awaited iPhone 7 (pictured is a concept drawing of the iPhone 7) has surfaced. Speaking to Bloomberg , a source said not to expect the MacPros to debut at an 'event currently scheduled for September 7 to introduce next-generation versions of the iPhone' The home button will be designed to read different inputs, using Force Touch technology And the iPhone 7 and 7 Plus will have the same 4.7-inch and 5.5-inc screens as their predecessors.

Blass has also made claims that the iPhone 7 line should hit shelves as soon as September 16.

This statement is the second time this week that Bloomberg released explicit news about the design of Apple's next-generation iPhones.

Earlier this week, Bloomberg release information that suggests next month's iPhone is expected to be much different from what is in your hand.

The larger iPhone 7 will be equipped with a dual-camera system designed to capture brighter photos with more detail.

This upgrade is just one of many rumors surrounding the iPhone 7 designs, as both models are set to have a home button that reads different inputs, but will be missing the traditional headphone jack.

'The standout features will be a dual-camera system on the larger iPhone, a re-engineered home button that responds to pressure with a vibrating sensation rather than a true physical click and the removal of the devices' headphone jack, said the people, who didn't want to be identified discussing unannounced features,' reports Mark Gurman from Bloomberg.

Although the handsets may be designed with new features, display sizes are not expected to change.

The iPhone 7 and 7 Plus will have the same 4.7-inch and 5.5-inch screens as their predecessors.

Sources also told Bloomberg that Apple removed the two innermost antenna lines that line the back of the current phones.

This statement is the second time this week that Bloomberg released explicit news about the design of Apple's next-generation iPhones.

The dual camera has been a long running rumor for the iPhone 7 and just a few months ago, a patent surfaced that illustrates this technology - sending the internet into a frenzy over the iPhone 7 Plus having 'superzoom' capabilities.

According to Bloomberg's sources, who claim to have used a prototype of the highly anticipated devices, this new system will snap brighter pictures in low-light environments and with more detail.

However, the dual-camera system will only be available to those who dish out the extra bucks for the larger iPhone.

The lenses, which each snap colour differently, will merge together to make one detailed image.

This technology would also allow users to zoom in on the object, place or person with more clarity, sources said.

Although this could be another one of the many rumors, September 7 coincides with Evan Blass's tweet from last month that reveals pre-orders for the iPhone 7 will start on September 9.

The home button has not been discussed too much this year, but it seems Apple could have big plans for this mechanism in the new models.

'Current home buttons are switches that physically press into the phone, but the new models will have a pressure-sensitive button that employs so-called haptic feedback,' according to Bloomberg's' sources.

'Current home buttons are switches that physically press into the phone, but the new models will have a pressure-sensitive button that employs so-called haptic feedback,' according to Bloomberg's' sources. Similar to the Force Touch technology used on the display

This technology is expected to be similar to the trackpads implemented in the latest MacBook line and what was reported by 9TO5Mac earlier this year.

Sources told the Ben Lovejoy that although the home button will still be a physical mechanism, it will 'feature haptic feedback to simulate a click using the same approach as Force Touch' – which was a new addition to the iPhone 6 line.

And the rumor that can be heard echoing all over the internet might actually be true.

Numerous leaks and sources have surfaced over the past year reveaingl a major change in the the upcoming iPhones, no headphone jack, which Bloomberg says will be replaced with a second speaker.

WHAT DOES THE INTERNET SAY ABOUT THE IPHONE7? One rumor has been debunked, which suggest there will be a single speaker instead of the dual speaker setup users had hoped for. But one thing that has stayed consistent is the dimension of both models, which were first revealed last year. According to reports, the iPhone 7 will have a 3,100mAh battery, which is 12.5 percent bigger than the iPhone 6S Plus. But although your phone will stay powered longer, it could also mean the casing around it could be thicker. What could be very exciting for iOS users is that Apple might be fixing the annoying 'there is not enough available storage…' issue with a 256GB this year. Another annoying feature that might be on Apple's to-do list is strengthening the phone's water-resistance. This doesn't say the phone will be water-proof, but it could make a world of a difference if you drop your phone in liquid. Advertisement

Users will also have to make use of connectivity using Bluetooth and the charging port to setup wireless headphones.

Another rumor hit the internet just last month that put an even bigger twist on the mystery, claiming next month's Apple smartphones will not be called the iPhone 7 at all.

Instead, it will be called the iPhone 6SE - leaving the iPhone 7 for next year, when apple is expected to introduce a major overhaul of its iconic handset.

The report from Apfelpage comes from Chinese supply chain sources, who claim to have have seen packaging and labeling that indicates the new phone will be called the 'iPhone 6SE'.
