Here’s what I said in a post (Anyone tried Widex Moment vs Signia AX ? (or Phonak Paradise) - #7 by x475aws) in another thread:
As for speech in noisy places, my reaction to how I hear store clerks and restaurant cashiers (some with masks and/or behind plastic) with Whisper isn’t just “I’m hearing them better”, but “Wow, I’m hearing them speak. These people have voices of their own, and they enunciate their words, they’re not just mumbling.” Maybe my reaction is over-the-top, but Whisper speech performance is a big improvement over what I’ve gotten used to.
It’s not clear to me how my performing A/B comparison tests would help you understand the Whisper experience better, or convince you that they’ve really accomplished something. Ideally you would try Whisper yourself as @happymach suggested…if they’re available near you, and if the audiologist says you’re in their fitting range.
