Thanks for your replies and help guys.
Playing now at a low volume for a bit to burn them in a bit.
About 20 mins into listening and my initial impression is that they seem weak in the bass. I am assuming this is due to them being new, and guess that it will improve after a few days of listening.
Aside from lack of bass, everything else sounds pretty good (ultra low volume right now). Nothing is sticking out as being glaringly bad, or anything like that. I will admit that the sound is more spacious (if that's the right word, maybe "airier"?) than what I expected. Sorry, I am not a headphone aficionado at all so I do not know what words to use to describe what I am hearing.
I have read stories of channel imbalances with headphones, so I was a bit worried, but the worry was all for naught. The left and right seem evenly balanced, and there appears to be no cosmetic/manufacturing defects of any sort. QC must be pretty tight at Sennheiser. a BIG thumbs up for that!
For initial non-sound related notes: I think these headphones are gorgeous looking. Pictures do them NO justice at all. You have to hold them in your hands to appreciate the real beauty of these IMO. I know looks are subjective, but the brown really looks nice to me. Really fitting look for an audiophile set of 'phones IMO.
I will continue to listen throughout the night, and will continue to post my impressions if anyone cares to read them.
Thanks again for your assistance guys. It really is appreciated.
