For what it’s worth, I currently have the OPN 1 as well, and I ALWAYS set my Noise Reduction max values to -9 dB (the highest I can go in the OPN 1, while the default is supposed to be at -5 dB) for Complex and -3 dB for Simple env. (default is 0 dB), and I never feel that the OPN 1 takes too much sounds away from me in noisy situations. So in my case I don’t follow what Oticon is pushing, I just be my own judge on what’s best for me.
What do you have your max Noise Reduction on your OPN 1 set to, Bill? You can play around with setting it between -5 dB and -9 dB and see if you notice any difference in noisy situations, and which one you like better. You can also set it to -7 dB, the in-between value. This will help you form a better opinion of which More to get, the 1 or the 2 or the 3. Like Jim said, the 3 will lack the Clear Dynamics that’s helpful for live music listening, though, if that’s what important to you.
