update:
I own 2 sets of TruHearing Aids. My original Truhearing premium th 5 that i got from the Audi for 3000.00 USD. And recently aquired TrueHearing premium th 6 that i bought from Ebay in Open Box condition for 300.00 USD. Economic reasons prevent me from taking these to the Audi to be fit and adjusted. So i decided to give DIY a try. Both the th 5 and th 6 are fully compatible with Connexx 9.12 software. i have made some small adjustment to my original HAs.And have done a first fit and minor tuning to the th 6. The th 6 was also due for a firmware upgrade which was successfully completed with Connexx. I am a total beginner at this , I just read through the self fit DIY school documentation and watched several Audiology Online videos. This gave me basic knowledge to make me confortable to give this a try. I believe other TrueHearing aids will also be compatible, like the TruHearing th 7 which is the current model in this line. I just wanted to report this out, because i’m sure other people wonder about fitting TrueHearing hearing aids. Btw, i used the Noahlink wireless tool to wirelessly connect my Ha’s to my computer. Worked like a charm! good luck.
