Recently sold most of my #headphones. Had conversation about #HiRes / #HiFi. #Recommendations: HiRes (FLAC) always sound better than CDs. You'll need 3rd party app to play FLAC. No reason to buy HiRes unless you have a HiRes music player (#AstellAndKern, #FiiO). You will need high-end WIRED (*no such thing as wireless HiFi) cans: open back #Grado #Focal, *some #Sennheiser; Or IEMs: FiiO (some more $ than others). Worth it if you listen to #jazz or #classicalmusic everyday. @jazz @classicalmusic
