I really like the Roger ON microphone. It has pointer mode, table mode, and presenter mode.
I try to position myself with my back against the noise (like in a loud restaurant). Then i position he Roger ON toward the people i want to hear. In the MyRoger app i can see a round illustration of the sound field, and i gray out the two back slices that point toward the noise.
Then i mute my hearing aid mics (you will have to ask your audiologist to enable that), because i dont want my hearing aid mics competing with the Roger On mics.
With this setup i can hear in noise about as well as the normal hearing people.
