Just came back from evaluating and learning about the Balance.
Balance is an upgrade to the already great Innova platform. The additions are in the way the automatic directionality (directional microphones) works. It is unique in it’s directional focus and also how it uses both omni and directional mics at the same time, frequency dependent.
The feedback cancellation is now active cancellation and deals with transient feedback, such as when you put a phone up to the ear, much better than the past.
Costs are about the same, only slightly higher than Innova, so it offers great performance without a significant raise in cost.
Balance is also now available in a mini-bte with earhook and can be connected to a traditional earmold/eartube, for a very powerful but tiny hearing aid.
I will be posting pics soon.
