Costco version Audéo Infinio or Sphere Infinio？

Can’t see why not, if Phonak want to stay competitive at Costco, they won’t have any choice.

Not sure when that will happen, I recently got the 30 pro, very disappointed with the noise, even after 3 tunings with the staff。 Is the Sonite larger than the 30 pro?

Yes it’s a little bit bigger form factor, not a huge difference, but what you could also is go DIY projects, it’s not hard and have a better chance of getting them dialed in, as obviously only you know what your hearing and how you like things to sound.

Roll a pair of dice. If you get more than a 6, say to yourself “probably”. If you don’t like the result, keep rolling the dice.

(No one knows and says anything so far. Pure conjecture.)
