While I like the concept, I don't think it's going to be very useful
A given volume, e.g. 50% can be vastly different on different headphones/earbuds. Only really useful on 1st party products
For me personally, I connect my phone to my car and always have my phone's volume at 100% for the Bluetooth because I control the volume with the physical knob in the car.
Man, I hate that BlueTooth doesn't have an equivalent of "line-out" that isn't affected by the host devices' volume settings. It's so annoying when I can barely hear my music because I turned the volume way down on my phone while watching a video late last night.
There's a setting in developer options to disable Bluetooth absolute volume. That can remove the sync from the media volume of your smartphone.
Poweramp plus allows you to set audio profiles for different devices, I have never gotten it to work properly between my bluetooth, wired headphones, and android auto.
Haha yea another good example of this not working as intended
This feature is only for wired headphones. They can not reliable calculate it for Bluetooth audio devices because of this very reason.
They can't do it for wired headphones either, hence why the current automation volume reduction sucks
It's should to be close enough, the spec is called sensitivity (SPL) and most headphone manufacturers try to hit around 100dB/mW.
Hopefully the setting would allow you to fine tune it based on what headphones you have.
Where exactly are you seeing that most manufactures are aiming for that spl?
I own many headphones all with vastly different sensitivities. And headphones are almost always far less sensitive than IEM's
Samsung turns the volume icons green beyond 60%, and it's much better than nothing; I would've raised the volume way above that way too often, if it weren't for that feature.
There's a feature to limit increasing the volume beyond some point, which—if you enable—you'd have to disable it to increase the volume, but I find it unnecessary.
