SAN FRANCISCO — Apple is set to unveil new iPhones at an event on Wednesday, as it has done every September for the last few years.
The event, which will be held in San Francisco’s Bill Graham Civic Auditorium, is the company’s most important annual outing. Even as the iPhone remains the outsize producer of Apple’s revenue and profit, sales of the smartphone have recently been declining. So more than ever, the onus is on Apple to keep up excitement for the gadget.
What’s different this time is that the rumormongers have been buzzing about something that the new iPhones will lack, rather than a flashy new feature. The item that is supposed to disappear is the traditional headphone jack, with Apple expected to turn people toward wireless headphones instead.
An Apple spokeswoman declined to comment ahead of the announcement.
Here’s a rundown of what to expect from Wednesday’s event:
■ The removal of the iPhone’s headphone jack, which will enable the device to become water-resistant.
■ A revised home button on the iPhones with 3-D Touch, a feature that activates different actions based on how hard the button is pressed.
■ The Plus model of the iPhone, which is the version with a larger screen, is set to include a dual-lens camera to take professional-grade photos.
■ A new version of Apple’s wearable computer, Apple Watch. The new model is expected to include a GPS tracker along with smarter fitness-tracking capabilities.
