The first part seems intentionally ambiguously worded to be interpreted as:
> (Stay connected with hands-free calls and messages) and (listen to your favourite tracks through built-in speakers)
vs:
> (Stay connected with hands-free calls and messages and listen to your favourite tracks) through built-in speakers
So it's not clear from that wording that there isn't a display, or that the messages are read aloud. An unambiguous wording would be:
> listen to your favourite tracks and stay connected with hands-free calls and messages through built-in speakers
As, well, the below statement is true whether there is a screen or not, and also doesn't specify that the messages are read aloud:
> No more stopping to answer your phone. Also, make calls and send messages on WhatsApp, Messenger and SMS, completely hands-free – simply by using your voice
That plus the image of the screen floating next to the glasses definitely make it seem like marketing is trying to trick people into thinking there's a display without explicitly claiming it
