IF YOU haven't yet forked out for a pair of bluetooth headphones, you won't like the latest rumour about the new iPhones.

A top Apple supplier has let slip that the upcoming trio of handsets won't come with the accessory required to connect a headphone jack to their lightning port.

Every new iPhone since 2016 has included the dongle out of the box to appease those who hadn't made the switch to wireless audio gadgets.

But you may soon be forced to fork out an extra 9 quid, on top of the high cost of a new iPhone, for the accessory come august.

In a note to investors, Cowen analyst Matthew D. Ramsay said Apple supplier Cirrus' guidance for its fiscal second quarter "all but confirms that Apple will not bundle the DAC headset converter 'dongle' in its new iPhone models."

The tip follows a similar prediction from another analyst made back in April, according to Apple Insider.

Apple ditched the headphone jack with the release of the iPhone 7 in 2016, instead funnelling audio through a new lighting port.

Explaining the decision on-stage during Apple's announcement keynote, exec Phil Schiller said: "The reason to move on: courage.

"The courage to move on and do something new that betters all of us."

But the move proved controversial, with customers insisting there was no need to remove the port.

And sure enough, many modern Android phones have retained the headphone jack (like the OnePlus 6 and Honor 1o).

However, there are some benefits to ditching the port: because the port has a fixed size, axing it can lead to slimmer devices which, along with creating all-screen displays, is another of Apple's long-term goals.

Plus, the future of phone charging is inevitably going to be wireless.

Apple phones have all offered wireless charging since the iPhone 8, which means you can use a special pad to power up the device without cables.

That means it is possible to charge an iPhone 8 (wirelessly) and plug in Lightning-connector headphones at the same time.

Apple is expected to finally launch its own AirPower wireless charging pad this September along with its new iPhones so the timing may be perfect.

Another recent rumour suggested that the next iPad Pro may also bin the headphone jack, so don't go expecting Apple to have a sudden change of heart any time soon.

Apple is tipped to release three new as-yet untitled iPhone models later this year, including a 5.8-inch iPhone X follow-up, a 6.1-inch LCD model, and a 6.5-inch iPhone X Plus.
