Apple has invited the media to an event on 7 September Screenshot

Apple is holding a media event in California on 7 September, where it is widely expected to announce the iPhone 7 and iPhone 7 Plus.

As well as new iPhones, Apple is expected to reveal a range of new headphones, including a pair of wireless earphones called AirPods and several additions to the Beats By Dre range. A second-generation Apple Watch is also tipped to be part of the event.

The presentation will be broadcast live online, and here is how you can watch it.

Simply head to the Apple website and the live stream will be ready and waiting for you at 10am local time (6pm BST) on 7 September. The only caveat here is that you have to use Apple's own Safari web browser to view it; Google Chrome, Firefox and others do not work with Apple live streams. Make sure your Mac is running OS X 10.8.5 or later.

The same website can also be used to watch the live stream on your iPhone, iPad or iPod Touch. Make sure you are running at least iOS 7, and again you can only watch it via the Safari browser.

If watching Tim Cook and co on the big screen and from the comfort of your sofa is more your thing, then fire up the Apple TV. A new channel will appear on the home screen several hours before the event starts; select this with the remote and away you go.

Now things get a little bit complicated. Windows 10 users can watch the broadcast through the Edge browser, but those on older versions of Windows will need to get creative. Install the VLC media player, which you can download for free here, then point it towards this link; it's the address the Apple TV uses to tune into Apple's live events. This is a bit of a workaround, and while it has worked for the past few years there is no guarantee it will work come 7 September.

If the iPhone 7 launch has peaked the interest of any Android fans, then you will need to download VLC too. Grab it here, then boot it up, head into the app's menu, tap the Stream option, then paste this link:

Press play to start the stream. Sometimes the link will appear broken until the stream actually starts, so you're best off waiting until 6pm before giving it a go. As with the PC method, this has worked fine in the past but is not officially offered by Apple.
