I agree with @phillyphil about having a separate device that is just music.
The two DAPs I own are low end, being the Shanling M2X and the M0, both serving different purposes.
The M0 is tiny and is great as either a portable player or BT receiver that I can clip on to the collar of my shirt etc. much like a BTR5 or similar but with onboard storage.
The M2X lives in my bag with the Starfield and whatever other IEMs I am listening to at the time. I use it daily to drive IEMs and it also comes in handy as a DAC/Amp for my work laptop when on the move (as does the M0). It can stream Tidal & Spotify and is also decent at receiving BT and DLNA streaming when moving around the house.
Yes, I could do all of this with my phone and a dongle, but both of these DAPs are non Android for a reason. Due to my job, my phone is constantly receiving messages, emails, calls etc. and there are plenty of times when I want to both save the battery of my phone and disconnect from the whole world. There are times when I just don’t want to be connected to the rest of the world.
As I said, neither are high quality DAPs but I don’t really need anything more than they give me. I don’t really follow DAPs as I have what I need, so upgrades in technology of DAPs don’t really interest me much. Once I am ready to upgrade a DAP, they only thing I will look for is better audio quality, the rest… I don’t really need anything else.
