It will be useful to me, but there's already a volume button. Would be nice if that just worked, instead of it being nerfed.
The volume limitations only made sense if you never used headphones less sensitive than the oem ones and listened to source audio that was only at maximum volume all the time.
But Sound Amplifier isn't about making the phone's audio louder - its purpose is to amplify the sound in the room around you and filter background noise. I think you're misunderstanding the feature.
