Budget phone, budget IEM, Spotify/YT. Don't bother wasting money on 1k DAC for this. The only difference you may see would be of volume level.I am using Redmi Note 11 and KZ Edx Pro Wired Earphone for on the go music.
Mostly listen from Spotify or Youtube for free.
A Portable DAC will worth to buy to have better music experience for me with above equipments ?
If Yes please suggest me something not more that 1K.
