Maybe someone else has the fitting software for Helix hearing aids? I don't.
I don't keep track of OTC (Over The Counter/Cheap Retail) hearing aids. It doesn't seem worth the effort ¯\_(ツ)_/¯
Here's a clip from a DIY School Hearing Aids (v2.2) PDF File named (Unlocking ReBranded Hearing Aids) which goes into many secondary brand hearing aids (but not Helix);
Big 5 Hearing Aid Models
Have you heard of the six major hearing aid manufacturers? At one time there were six major hearing aid manufacturers. But then WS Audiology/aka Widex merged into Sivantos/Signia/Rexton, so now there are five.
See the DIY School PDF file titled (Big-5 Platforms Chips). It has a red YYYYY-QQ legend that corresponds to the original date of the new platform when/if it contains significant new hardware (chips/CPUs/processors). This red legend may be helpful in determining which platforms are actually new? Also, you can view an industry image map that groups the Big-5 manufacturers (in image format) → Abram Bailey's Hearing Industry Map.
This document does not discuss (loosely related) sister companies such as ("Phonak/Unitron") and "Oticon/Bernafon/Philips") because most ReBranded hearing aid models come from the Big Five, not from sister companies. However, there are exceptions (for example Unitron).
