@Volusiano, it may take me a couple of posts to answer your questions. The Mores are set up so that Open Sound Booster is on all the time.
The Whispers seem just as “open”” as the Mores, if not more so. The mid-rangey tone of the Whispers might have something to do with that.
Subjectively, it seemed to me like when I encountered the crowded kitchen with everyone talking at once, the Mores jumbled everything together into a cacophony where I had to listen very hard to pick up individual voices. The Whispers took the same soundscape and made it sound like there were several conversations going on at once, and I could choose which one to concentrate on. Kind of like normal hearing. To be sure, the Whispers did not do this perfectly, and it was still a difficult environment. But the difference was pretty striking.
The prospect of frequent AI software updates is promising too. But I wonder if the update process will (or already has) encounter the law of diminishing returns, with each new update delivering less-dramatic improvements than the last.
