From the inside, the word is - no different. Just a designation for pre-release samples.

Oh OK, that's cool. It's just made in a low volume to cover samples and a limited edition run, that's fair enough. I saw a different model number and my brain made the leap. Thanks for clearing that up, I didn't read anything definitive mentioned on the website.
The white M80's were announced ages ago and apparently some people got samples months ago, and in spite of my privileged position I didn't get one until last week. But worth the wait! The sound is impressive and the design is really cool, with the option of custom side plates. I honestly think the white M80 is the best looking portable headphone ever made, and I can't even think of a big-stereo headphone that looks as good.
