The first question I want to ask you is whether you feel that the Whisper gives you the exact same openness like the More does overall or not, especially in a noisy room where many people are talking. One possibility I can think of is that the More, in trying to preserve the openness that its open paradigm espouses, and especially in situations where there are all kinds of voice cues existing all around the room, it may try to preserve all the voice cues too hard and not drop any of them in favor of any particular one (primarily the front one) that it allows them to compete against each other and therefore make it a harder job for you to zoom in and focus on the one voice cue you want to listen to. Having too many voice cues competing all at once can be overwhelming to you for sure. If you’re in that situation often enough, maybe you can learn to sort them out better. But if it’s only a rare occasional thing, you won’t have the practice you need to make your brain hearing fit enough to be able to sort them out by itself without resorting to some kind of directionality help.
One thing I don’t now if you’ve tried out in that scenario or not yet, is to invoke the MoreSound Booster in the ON app. It’s supposed to give you a more directionality focus toward the front and reduce the sounds and babbles (other voices) on the sides and the back of you. If you didn’t try it then, I wonder if it might have helped you more in that situation. After all, that’s what the MoreSound Booster is designed for, to deal with exactly the kind of situation you were in yesterday.
I really don’t know if the Whisper puts any kind of directionality focus on the front to help you hear better or not, so that’s why I asked you earlier how “open” do you feel the Whisper is in that same situation. Did you feel like the Whisper allowed you to hear all the voices the same way the More did, to the point of not knowing how to zoom in and focus on a particular voice? Or did you feel that the Whisper seemed to know which voice you wanted to focus on and changed the balancing between the voices to favor the one you wanted you hear. If so, was the voice you wanted to hear in front of you usually because you may tend to turn your face toward the voice you want to hear to focus on it better?
@SpudGunner made a good point about maybe backing up on the max NNS value to 8 dB to see if it helps or not. But lacking the DIY ability to set up both to toggle back and forth, I’d still rather you had the 10 dB setup to try that out first in a very complex situation because those situations do warrant a 10 dB setup and it seems like your audi and the Oticon rep concur on this point. If the 10 dB weren’t going to be helpful in that situation no matter what, then it’s Oticon’s bad to make the 10 dB available but yet can’t be helpful to the users when they need it the most in the first place.
This reminds me of @abarsanti’s comments about how he thought the Philips HearLink 9030 was very good in doing speech in noise suppression with its DNN, probably even better than his OPN 1, but in the end he went with the More anyway because he felt like he’s willing to sacrifice that superior SIN performance from the HearLink if he can get back his openness that the More gives him. So the one thing I’m very curious about the Whisper is how “open” it really is, in less complex situations, and also in very complex situations. Almost all of the 3 or 4 Whisper trialers seem to have commented that the Whisper seems very open just like the Oticon open HAs. But I still wonder if you really pay attention to the “openness” between the Whisper and the More, whether you find them equally open or whether one is more open than the other.
This may have a bearing on perhaps why the Whisper seems to outperform the More in very complex SIN situations, if the More chooses to be more open at the expense of having a lesser performance, and the Whisper chooses to be more directional at the expense of being less open. Of course, this is only a hypothesis on my part, I’m not saying this as a matter-of-fact-ly at all. Only you guys can form this kind of opinion based on your first hand experience.
