It change nothing: echo cancellation is to limit echo from hardware but 
you will always have the sound going out from loudspeakers and coming 
back to your microphon. This echo (reverberation) will never be 
cancelled by the echo cancellation feature as it is part of user audio 
(as would be the music from your radio if you don't switch it off  when 
your in conversation ;-))
