No, the device does not have Bluetooth ...
... but a headphone socket;
I was unable to test whether this also supports wired headsets.
But: hands-free function is very good! Clear and interference-free voice transmission (e.g. handset placed on table, leaving hands free for computer keyboard etc.). I almost always use it.
Of course, it's no use if you don't want anyone else in the room to overhear the sound of the person making the call ;-)
