We have ordered over 10 of these headphones, but unfortunately we cannot guarantee that they will arrive in our warehouse in time for the sales launch on 12 January.

Plug the USB dongle into the front of the PS. Done. If necessary, press the pairing button on the headphones (if you have them in your ear, the button is slightly hidden on the underside). And of course charge the headphones in/with the case beforehand if necessary ;)

After further research, the question has become superfluous, the invoice will only be sent to me by e-mail after the parcel has been dispatched.

The Sony Pulse Explore Earbuds are optimised for the PS5, but they are also compatible with the PS4. They offer a wireless connection via a USB dongle that works with both PS4 and PS5. However, they are specifically designed for the PS5 to take full advantage of its 3D audio functions.

No, you have to connect the charging station of the headphones to the console once with the supplied charging cable so that they can update themselves once

Yes, that works. A USB adapter is also included.
