I got my Pro 30s on Tuesday at Anchorage Costco. Appears that in non-AI mode, batteries will easily last all day (14hrs) with greater than 50% charge remaining. Suspect that Pro 30s in non-AI mode may be similar to Pro 20s in many respects. I ran AI assisted yesterday for several hours (~5 or 6 hrs) and ended up with dead HAs at around 14hrs. More details to follow.
