Yes, sorry... I wanted to say that if you need things like what Oticon names as: soundbooster, noise reduction, transient noise management, spatial noise management, feedback management, speech rescue etc. I take those features involve heavy digital processing, and the Mores have an edge over the OPNs in that regard.
The MoreSound Booster is available in the More (of course), but not in the OPN. However, if you just change the Directionality Setting in the OPN to Full Directional, and max out on the Noise Reduction values in a Speech in Noise built-in program, then you'll have what the MoreSound Booster should be. It won't be in the ON app, but it'll be in a dedicated program on the OPN that you can always select when you want.
The Speech Rescue is really the same from the OPN to the OPN S to the More to the Real. There's really no further improvement there.
Transient Noise Management is also the same from the OPN to the OPN S to the More. In the Real, it gets replaced with the Sudden Sound Stabilizer.
Spatial noise management is pretty much the same from OPN through the Real as far as I know. It's built-in and not really adjustable anyway.
Feeback management has a new and improved feedback prevention technology called the Optimizer starting with the OPN S through the More and Real. There's no improvement there, except that the original OPN doesn't have it. In fact, it's the main difference between the OPN and the OPN S, aside from the option for a Lithium-ion rechargeable battery on the OPN S that is not the ZPower system. The OPN only has the traditional reactive feedback management, and this technology also carries over to the OPN S and More and Real and can be turned on to work in conjunction with the Optimizer feedback prevention.
The noise reduction is the same on the OPN and OPN S (called the OpenSound Navigator), but changed significantly on the More (and the same carries over to the Real) using Artificial Intelligence's Deep Neural Network to implement noise reduction (called More/RealSound Intelligence).
All in all, the 3 most significant differences between the original OPN to the More/Real now are: 1. The new feedback prevention, 2. The Lithium-ion rechargeable option, and most significantly 3. The use of AI DNN for noise reduction. For folks who are pretty much happy with the OPN and have no issue with feedback, the AI DNN in the More/Real may not turn out to be a big wow factor for them though.
The rechargeable Lithium-ion option after the OPN is not necessarily a big plus either. Many folks find it unreliable so now Oticon has put back the disposable battery version to give users more options.
