If we’re talking about new releases, Oticon is coming out with the Oticon More early next year which is supposed to be the next generation Oticon line after the OPN S. It’s too new to really know how well it’ll work, and how soon after the initial release will it eventually offer a “power” version of it. Probably with a similar schedule compare to when they come out with the “power” version of the OPN. But if anything, it’s worth checking out the forum thread on its release announcement just so one is aware of all the options in terms of new model releases from HA mfgs.
For Accessories, Better App and more power before feedback, Quattro Enzo is also worth a shout.
Not sure if it’s just me, but the Sonova feedback manager dancing all over the output has never given me a lot of confidence that their usable gain was where it was claimed to be (certainly not where the REAR said it was).
Oticon have lots of experience with chunky high power aids too, but their Open strategy is a bit ‘marmite’ for some users; power users tend to be very definite about their preferences in this respect.
