BlackBerry Motion (BBD100-2) with Android 8.1 running Poweramp alpha 709.
The volume with a wired headset is much lower than the OpenSL ES Output though.
Works great on my BlackBerry PRIV running Android 6.0.1. I had to set the visualization delay to 150ms to get the vis to match the audio. I left all of the other settings at their defaults.
