Here's a fix that makes it work better. It's question of loading pulse audio bluetooth discovery module too early, so user doesn't have access to it. This solution helps me get the Bose QC35 to work, after I hammer the bluetooth connect button few times. But without this fix, there is no chance to get them working:

    Bug and possible solution: actually I found a bug in that make the headset unusable, it seems that the pulse audio module: module-bluetooth-discover works only if started after the X11 session is up. So I have a workaround.

    Edit the file:

    /etc/pulse/default.pa

    and comment out (with an # at the beginning of the line) the following line:

    #load-module module-bluetooth-discover

    now edit the file:

    /usr/bin/start-pulseaudio-x11

    and after the lines:

       if [ x”$SESSION_MANAGER” != x ] ; then
            /usr/bin/pactl load-module module-x11-xsmp “display=$DISPLAY session_manager=$SESSION_MANAGER” > /dev/null
        fi

    add the following line:

        /usr/bin/pactl load-module module-bluetooth-discover

    This way the Pulse audio’s Bluetooth modules will not be downloaded at boot time but after x11 is started.

Problem with it is that this gets overwritten in my laptop while RHEL pulls updates, and I need to manually fix it again.
