Apple

Not that the audio quality of the apple watch speaker matter that much, it's pretty much just for Siri and notification sounds, but when I got my girlfriend the Ultra 2 (I have the Ultra 1) I noticed that the audio whenever Siri talks is way more rich, nuanced and less tin sounding in the newer Model. There haven't been any official Apple information about the new speaker but did anyone have both models and made a similar discovery? Or maybe my Unit is just faulty, I had to already replace it once at the Apple store. Compared my Speaker sounds really terrible.
