You should post your audiogram on your avatar so we can tell what kind of hearing loss you have. That would help a lot in providing the proper suggestions that would work for your type of hearing loss.
It’s really hard to say if the More 1 will help you understand speech better than the More 2 when you’re out with a group of people or not, because the More 2 is no slouch. It’s a very solid hearing aid all by itself, even if it may not be as robust as the More 1.
If you look at the screenshot below for the More DNN settings, in the Environment Configuration section, you’ll see 5 situations depicted, from Very Simple to Simple to Moderate to Complex to Very Complex. I would say that the More 2 should be able to help you manage up to the Complex situation competently. The More 1 may have an edge over the More 2 in the Very Complex situation, but not necessarily so, depending on what max value is set for Neural Noise Suppression. You can see the difference between Complex and Very Complex depicted as more people, multiple speeches going on around you, along with music and mechanical (fan) noises going on in the background for a Very Complex Situation.
In terms of noise reduction for the Difficult Environment, although the Neural Noise Suppression on the More 1 can go up to 10 dB maximum while the More 2 can only go up to 6 dB maximum, it’s generally suggested to use the default of 6 dB max Neural Noise Suppression even for the More 1, so if the More 2 is also set at 6 dB max Neural Noise Suppression as the default as well, then there’s really not much difference there in the amount of noise suppression between the two.
If money is very tight for me personally, then I probably wouldn’t have any qualm sticking with the More 2 to save the $600. But if I can afford it, I think it’s worth spending the $600 to upgrade to the More 1 just so I know that I have the best regardless of whether I need the best or not.
