Pros: EVERYTHING...from looks, to sound quality, to build quality, and comfort.
Cons: None so far
Nothing more to say. I am not an audiophile, but I wanted to be a part of the community. So, I started with getting the M-80, and boy am I happy I did. It looks extremely good, the packaging was perfect, the sound is outstanding, the build quality is fantastic, and it is comfortable at the same time. I was surprised at how compact it is due to it's excellent case design. The #1 reason I got these is because of it being the first in on-ear headphones on head-fi. I found this website almost 3-4 weeks ago, and I am happy that there is such a community. Anyways back to the headphones, these are exactly what you would expect to get from paying $160. All in all, if you have the money go buy it right now you will be amazed.
