[Here’s another answer in a similar vein, but with a few variations on the theme.]
@MDB and @Volusiano have got the answer to your question nailed down.
"I currently wear Oticon More1 hearing aids, which I’ve had for three weeks. Prior to that, I wore More3s for a month.
(I paid an upcharge of $1,500.00 Cdn for the privilege of wearing Tier1 technology - my wife’s group insurance covered 80% of that, leaving me with $300 to pay out of pocket.)
I made the change to take advantage of the More1 feature called ClearDynamics, which provides a 113dB input ceiling that makes my live guitar playing sound fuller and “richer”, to use that hackneyed term.
Another More1 feature that I wanted was a 10dB noise suppression capability, versus the More3s 6dB attenuation limit. This extra noise reduction is helpful in a very noisy environment, but is imperceptible in a quiet or moderate noise situation.
Streaming music, phone calls, input from remote mics is the same for either More3s or More1s, so there’s no advantage to be had here to justify the upcharge.
If it hadn’t been for my wife’s additional coverage for my hearing devices, I wouldn’t have moved up to More1s. I decided to take advantage of the additional funds to get better rendition of LIVE MUSIC and not canned entertainment (I’ve played solo guitar professionally for over 50 years).
The More1 devices have proven their superiority in that regard, and they do provide better noise limiting in very noisy settings
So - I’d say that More1s are worth the $300 they actually cost our household budget, but they’re NOT WORTH THE $1,500. 00 (+35%) UPCHARGE over the More3s for someone with a relatively quiet lifestyle.
For the record: I could have lived with/gotten used to More3s for my music - yes, More1s are better, but More3s are by no means unacceptable.
On the other hand, Oticon’s OpenSound concept allows the wearer to hear more sounds emanating from the sides and back. More technology uses AI to attenuate, but not totally suppress, the sounds it labels “noise”.
(I’m uncertain whether it actually boosts speech sounds, but it’s supposed to "clarify " them. In any event, the SPL differential between speech and noise created/enhanced by MoreSoundIntelligence definitely is effective for me at improving speech intelligibility.)
Previous users of directional, beam-forming hearing aids can initially be overwhelmed by the broader palette of sounds their brain hears in the OpenSound world. For these users, the extra noise suppression provided by More1s would probably provide a more comfortable (and ultimately successful) transition to Oticon’s sound treatment philosophy.
If I were still working, and in a dreadful, open architecture “bullpen” again, I believe that More1s would provide better speech-in-noise performance. Otherwise, there’s really no good reason to discount More3s ability to deliver very good results.
Perhaps More2s would be the best of both worlds (top-tier performance vs economy)? I dunno because I have not done any research on More2s.
That’s my $0.02 worth for now. I intend to post a detailed comparison of More1s vs More3s in a few weeks (after my next audiologist appointment on June 10)."
