If the recording is bright, would it sound the same on the 650s?
My pair does sound bright now and then. I will give them some more time like a week to settle and report back.
Great idea to give it a week.
Everyone's idea of a bright sound is a little different, if you were using Beyer's or Grado's then the HD-650 might seem quite dark sounding, if you were listening to Beats or Bose then the HD-650 might sound bright to you, its really a matter of your experiences and your individual hearing and preferences.
Think of it this way, many compare other headphones to the HD-650 and HD-600 so in the future you will have a great point of reference when someone describes a headphone to you since many will compare new headphones to the HD-6XX series since they have been around for a very long time and almost all are familiar with their sound.
