> want better sound quality
then use eq retard
>I want higher driving power and balanced output
Audiofool meme shit. I bet your iems have high sensitivity that isn't needed at all. Also balanced output is snake oil.
>I don't want to drain my phone's battery any faster
playing back music on your phone barely uses any battery at all
>I want physical buttons
that's a want not a need, and a touchscreen is better
>I want a smaller device
carrying two devices is heavier and takes up more space
>I want the ease of use and not having my music playback interfering with phone's other functions
just don't be a retard and you won't have that problem
>I want to be able to use microsd cards to store my music
then get a phone with a microsd card support like Sony. Also it better to setup a navidrome server and stream your music.
