Beltone Trust 17 has the same feature set as ReSound LiNX 3D 9. One is not better than the other. Make your choice based on the hearing care professional that provides the best service.
I’d at least go and try the Resound aids. With the products being the same or close and you already having the Linx, I doubt it will improve a lot. The latest Linx 3D can be remotely programmed for you over the Internet and it is as good you can revert it yourself. That’d make up for the extra drive.
Actually the Beltone Trust does the same. I am hoping for improvements in group situations. Linx started to do that with their 2 and they could not use software to do the same trick with the 1. The info on Beltone Trust reads identical to the Linx 3D.
I really like my Linx3D’s. THey indeed have the remote programming feature and my audiologist said if I wanted to do that she would learn how to set it up. I actually just went out and bought an Airlink2 so I could program them myself (She said “You did what?” when I told her).
