Though smartphones can be used to listen to music, they can't compete with high-end music players. Toward the top of that list is Sony's NW-ZX707 Walkman.
oh boy everyone will argue about audio specifications again. For the record standard MP3 is fine and is perfectly representative of the recording it did within the bandwidth of human hearing
That depends on which MP3 though. Is it 128kbps? Because that's dog shit. 192 will sound fine to most. I don't go below 256 and that's only if I can't get 320.
