They would not hear much difference, but they will probably be able to hear
some in an A/B comparison, because their filter does not cut off absolutely
at 2.7KHz or whatever, so some of the extra information will get through.

But you will be wasting power generating frequencies that are more or less
wasted on the station you are working, and which could be causing QRM or
simply taking up space that someone else could be using. In my opinion, it's
only appropriate to use ESSB when you know that the other station is also
equipped to receive it, on a band that is quiet enough that the wider signal
is not preventing someone else from having a QSO. From that standpoint, it
is a pity that it has to be enabled or disabled by going into the CONFIG
menu, because that seems to imply that it is a setting that people will
either use most of the time or not use at all, rather than something you
enable (perhaps using MODE ALT) for a particular contact when circumstances
permit, and then turn off when that contact has ended.
