Just curious why you didn’t try the Passion 440 which would be the same size as the Passion 115 but with enhancements (newer software). The Mind 440 is a larger-sized micro BTE.
If you think you will use wireless accessories, you may want to wait for the new Clear 440 which will be launched next month (but will be high-end, therefore priced accordingly).
There will be a model the same size as the Passion 115, but offer new enhancements plus a remote control and devices for connecting with a mobile phone and TV. From the promotional literature, it will offer the highest audio bandwidth compared to anything else out there, plus the best wireless performance (lowest delay of < 10 milliseconds).
There will always be a “new and improved” version coming out just around the corner, so it is up to you if you want to wait. Keep in mind though that the purpose of a hearing aid is to help you hear. The devices you have been testing certainly deliver in that regard. Only you can tell if one is “better” than the other in helping you hear.
If you are not much of a gadget geek, then I wouldn’t worry about the new wireless accessories. Of course, wireless technology is not just about accessories. With hearing aid to hearing aid synchronization and coordination, it is purported to enhance sound perception. My sense is, it will be some time before hearing aids can offer a significant benefit over existing sound processing until there is significant leap in processing power of the chips (without increasing power consumption). In other words, I don’t buy the sales pitch on this front quite yet. This is purely my opinion. Others on this forum I’m sure have another opinion.
Good luck with your decision. I know it is not easy. But you’ve taken a significant step in recognizing that hearing aids can improve your everyday life. I can certainly attest to that.
P.S. as for using a remote. I used one with the PA115 (which came with a remote) for about two months or so. Haven’t touched it since.
