My game it has many buttons. Button has the same sound effect. When I build and test in iOS my sound it’s not good equal my MacBook.
It wouldn’t hurt to be more descriptive about what is not equal.
Of course sound is always different on every device but in case if you’re talking about the quality you’ve set it to Vorbis.
is it a .Wav file being compressed to vorbis? then that might cause the quality difference (besides the different speaker built in the device).
Vorbis/Mp3 gives a lower quality sound and that will reduce the build size.
If you want a higher quality you could try PCM, this will increase the size but it will be higher quality.
Take a look at the import settings:

That might have to do, with your built in soundcard and speakers too.
MacBook and laptop speakers, sound better, wider and more fuller
than iOS or samsung galaxy built in internal speakers.
