Unfortunately you are right, not until Audeo B Direct is there a new chip (SWORD).
"The Audeo Belong Receiver In Canal hearing device range is the first Phonak hearing device range with a rechargeable option. This in itself is quite an amazing innovation and a new direction for them. However there is much more that is new in this range than just that, the Belong comes with an upgraded operating system, the latest version of Phonak’s SoundRecover2 and new microphones and programme buttons.
The range uses the existing Venture chipset…"

I’m not sure when they say “upgraded operating system” what that means when they also say the Audeo B “uses the existing Venture chipset”
I wonder how important SoundRevover2 will be for me. It might be valuable since I have so much loss in the higher frequency range.
