This is the newest model from Audeze. The part number is 100-LX-1016-00. This is the Creator Package that comes with the new economy travel case. I'm switching to closed-back XC due to a noisy environment, but these are in like-new condition with just a few months on them. Comes with everything they came with directly from Audeze. Price includes PP fees and shipping so I'm standing firm. Feel free to check out my sales history. Buy with confidence.
