I get a feeling that you’re going to like the More 3 a lot if you prefer the open dome for minimal occlusion. That has been the hallmark of the OPN S’s feedback prevention technology, which is also carried over to the More as a whole without any degradation between the More 1, 2 and 3 line. So much of a hallmark that when they released the S, Oticon touted the ability to wear open domes and not having to worry about feedback as the key breakthrough they had with the S.
Another thing is that I think the handicapping between the More 1, 2 and 3 is probably less severe than that of the OPN 1, 2, 3 or OPN S1, S2, S3. That’s because on the OPN, the most significant handicap is on the Max Noise Reduction value, in which the OPN 1 has 9dB, OPN 2 has 5 dB and OPN 3 has 3 dB. This makes the OPN 3 not have as optimal a performance in noisy environments.
But the More line kind of does away with noise reduction the old fashion way. Instead of focusing on noise reduction on speech per se, it uses the deep neural network to balance out the various sounds better, so that important sounds like speech become more prominent and less important sounds are balanced out more to the background.
As a result, you can see by the comparison chart below on the MoreSound Intelligence section that most of the differences between the More 1, 2, and 3 are more along the lines of options and configurations, and less along the line of noise reduction. Even the neural noise suppression, which I think is not really noise reduction in the convention sense of SNR, but more like more optimal or less optimal balancing of sounds, the Difficut Neural Noise Suppression of the More 3 for Difficult environment is at 6 dB, the same as in the More 2. The Easy environment for the More 3 is at 0 dB, but it’s less consequential in my opinion because Neural Noise Suppression is probably not really needed for Easy Environment anyway. The Spatial Balancer of the More 3 is the same as that of the More 2, at 60%. So if these 2 crucial parameters in the MoreSound Intelligence (for speech understanding) are almost the same between the More 2 and More 3, then I think the More 3 will probably perform more or less the same as the More 2, except that you have less options and configurations to choose from, that’s all.
The MoreSound Amplifier is another key technology introduced in the More line and not available in the OPN line. But as you can see, it’s not watered down between the More 1, 2 and 3 at all.
So my point is that overall, the performance of the More 3 is probably not going to be that drastically different than that of the More 2; you just have less choices on a number of things. This makes the More 3 a more viable option as compared to the OPN 3 in terms of performance, as compared to the 1 and 2.
I wear an OPN 1 but I had an opportunity to try out the OPN 3 for a couple of weeks and I’ve posted a review of the OPN 3 here on this forum. Overall, I found the OPN 3 still a very respectable hearing aid when compared to the OPN 1, just slightly lagging in a few areas. My hunch is that the More 3 is also going to be almost as respectable in performance compared to the More 1, and if money is a significant consideration for someone, the More 3 may even be a better choice in terms of value for the money. But naturally speaking, I don’t have any experience with either the More 1 or the More 3, so this is all a guess for now of course.
