The tech giant are expected to officially confirm details of the upcoming smartphone range at a press event in New York tomorrow (15.10.19), but ahead of the reveal, 9t5Google has claimed a leaked picture of the box shows that there is no headphones or a converter included.
However, it does come with a 18W USB-C power adaptor with a charging cable and a Quick Switch Adaptor.
You will instead need to connect wireless headphones via Bluetooth or buy an adapter.
Although the event hasn't been specifically named as Pixel 4 reveal event, Google has a history of making Pixel-related announcements in October, as well as Home smart devices and Chrome laptops and tablets.
Meanwhile, it was recently revealed that the smartphone will have face unlocking like Apple's FaceID.
The firm teased some new modifications coming to the upcoming model in a video teaser, entitled, ' (Don't) hold the phone: new features coming to Pixel 4'.
It's also been revealed it will feature a single front-facing camera.
And it was previously reported that Night Sight will be one of the Pixel phone's main camera modes.
Google has revamped its list of modes and swapped out panoramas in favour of its feature focused on taking photos in bad lighting.
According to 9to5Google, the leaked Android Q beta build revealed the switch, which sees Night Sight listed as the mode on the far left.
If the format remains the same, the modes listed in the main viewfinder will be Night Sight, Portrait, Camera and Video.
The 'more' tab will include Panorama, alongside Photo Sphere, Photo Booth, Slow Motion, Time Lapse, Playground, Lens and Settings.
Meanwhile, the same update appeared to show that the ability to adjust white balance in photos has been removed.
While it could be a bug in the unreleased beta software, the temperature icon - which allows users to choose from different preset options - doesn't seem to be there anymore.
