Hi Earfun :)
Big fan of the Air Pro 4's, but just one thing could do with a tweak.
I think it would be great if the app lets you change the volume increments, as right now there is too big a difference. For example, the music is a little quiet, so I increase the volume once, and then it's too loud. Perhaps if we could have a setting where adjusting volume can either be 2%, 5%, or 10%, so people can really fine-tune how they want the volume to change.
Hopefully the product team will see this!
Cheers.
