On a recent hiking excursion where I was leading a group of people on a history hike, I was able to try the different modes. Public speaking events, where I have to field questions, has been particularly difficult for me with my hearing loss. The Live Music mode suppressed the side noises and the person in front of me sounded clear, even when they were twenty feet away. I did switch to Outdoor mode so I could easily talk to the person next to me as we were hiking on the trail.
