I find using Qobuz on my dap and carrying it in one pocket, with my phone in the other, a far better and more enjoyable experience for me than having a dongle connected to my phone.
I find the whole experience of carefully taking my phone out of my pocket, then holding the dac awkwardly whilst using my phone to then carefully place it back - really tedious and annoying.
I’ve even tried just tying to ignore my dac and let it dangle when I pull my phone out to use, but that’s annoying also.
I’ve also tried using a magnet to hold the battery to the back of my phone and using this contraption:

Which is a decent solution, but I still prefer not having anything tethered to my phone.
Having a dac tethered to my phone also significantly drains the phones battery.
Once I got my dap, I’ve never looked back.
To each their to own, everyone’s different after all.
