The mega event at the Bill Graham Civic Auditorium in San Francisco will unveil the iPhone 7 and the iPhone 7 Plus smartphones along with the next-generation Apple Watch, appleinsider.com reported on Friday.
The company has reportedly sent out invites to select media to cover the launch of iPhone 7.
Apple acquired the headphone manufacturer Beats for $3 billion in 2014.
It is still unclear what kinds of Beats products will be unveiled, but the brand is known for a variety of headphones and portable Bluetooth speakers.
"Apple is also expected to unveil new, entirely wireless Bluetooth earbuds dubbed "AirPods" at the upcoming event. Whether the product will be sold with Apple or Beats branding remains to be seen, " appleinsider.com reported on Friday.
People can pre-order the luxury smartphone from September 9 while sales may begin from September 16.
The new iPhone 7 may have a dual rear camera, a pressure-sensitive home button, Bluetooth-supported headphones, dual speakers at the bottom and Type-C interface, signalling the end of the 3.5 mm headphone jack in the iPhone family.

To date, Apple has kept Beats products largely separate from its own. Devices like the iPhone still ship with Apple-branded EarPods, while Beats headphones are sold separately, the report added.
