After congratulating all of you that rooted for the Ravens and commiserating with those of you that rooted for the Niners (including myself), back to serious business :). Although Hifiman claims the HE-400 can be driven by the iDevices, in my 3-day experience, I find that is just not the case (though the Ipad 3 is better) and amping is necessary. Has that been your experience as well ?
Second, I have plugged the HE-400 to my iDevice and playing it almost continuously for 3 days now as part of the "burin-in" process. Is this necessary or overkill ?
Lol just listen to them and you will see :)
Nobody never said you cant listen during burn-in :D
Also, you should listen slightly louder when burning them in so keep that in mind as well :P
