I haven’t tried streaming music from my phone much. In my car with my open domes, I could get a lot of bass from my car speakers, which are those in a top-of-the-line Accord. But I noticed in the Smart 3D app, there is an option choice to enhance bass as much as possible in streaming - I’ll have to give it a try. Audio podcasts of the human voice sound great when streamed - having all the “s” sounds, etc., that I was lacking before.
Might be the placebo effect but if you’re using an Android phone, might want to check the phone audio settings (don’t know about iPhone). My Samsung phone running Oreo is normally running “optimized” settings - meaning everything is scaled back a bit to avoid chewing battery - but there is an “entertainment” setting that promises to enhance the quality of digital audio - I think it’s supposed to upscale it to a higher audio bitrate just as with video a DVD can be upscaled from 480p to not look crappy when displayed on a high-definition TV. Whenever I go walking and listening to a podcast, I switch to the entertainment setting (my screen is off so I’m not burning extra battery lighting up a max res “entertainment” screen, too) and I like to think that the audio sounds better than ever! I have a good imagination!
