Depending on the particular DAP there may be physical size and storage advantages. Furthermore most ‘premium’ smartphones do not come with a headphone jack meaning that the audio experience using a decent pair of IEMs will be an improvement on listening to music on a smartphone via a pair of wireless headphones/earbuds.
P.S. I’ve yet to come across a pair of wireless earbuds that are as comfortable or sound as good as my favorite pair of IEMs.
Some people like to enjoy their media without having to use a smartphone, they prefer to keep their smartphones as strictly communication devices. Doing so allows them to switch off entirely when at their leisure in addition to saving phone battery life.
2tb of removable storage dedicated to music and the existence of a headphone jack are significant advantages for me. Not that I would purchase this particular contraption but I understand the appeal of single function/media devices such as DAPs and ereaders.
I haven’t seen a device that takes full sized sdhc cards in at least a decade.
newsboat and mpv are awesome. How is nsxiv better than sxiv?
