Pros: The sound is full, detailed and amazing!!
Cons: If price isn't an issue get it
I got both hifiman 801 and the colorfly c4 to try out. Sorry to say but I couldn't tell any difference between my iPod classic and that. The c4 on the other hand just blew my mind!! Sound is amazing!! I'm not audiophile but try both hifiman and c4 side by side and you'll see yourself how amazing this player is!! Dont listen to people who say it isn't good!! Try it out for yourself!
