So...A $12. Android DAP that absolutely kills it...
Add a $3 128gb and you have a player full of free Android apps like Musicolet, unlike my iPhone I can set a systemwide EQ based on my IEM at the moment with a free app, and I have put 50gbs of FLAC files- a direct wire transfer from my Mac- drag and drop the music files onto it- with a $30 (lifetime) program called MacDroid. With the excellent KZ EDC Pro that I got for $4 and a dongle I got 4 for $9 on Amazon you're looking at $20. worth of Bluetooth, wireless heaven. Buying them 5 at a time to give away.
