I like to keep music playback separate from my phone because I hate having it interrupted by some random app notification. And on my smartphone I have to push the volume to the max to barely reach the level I consider normal with my headphones. On the Walkman that's not an issue and the difference in sound is immediately noticeable. Of course that doesn't matter if you use Bluetooth, but as there isn't a single decent pair of BT headphones with replaceable batteries on the market I'll keep using cables in the foreseeable future (and headphones have a minimum size, so the manufacturers can't even use their typical excuses for using glue). Of course some phones are quite solid in terms of sound, with some music there's no difference either way, but without comparison you can't really know what's missing unfortunately.
