Oh my... I know people keep bragging about how comfortable these are but... damn. These things feel ludicrous in comparison to the HE-400s. After lounging around in despair in not being able to decide between the hE-400 or the Mad Dogs, I finally decided to take the plunge and get both to compare them for myself. I've had the HE-400's for the past 6 days, and now have the mad dogs today. Got here quicker than I thought, ordered on Saturday. I'm not quick to judge, but I already like the Dogs better; better feel/buil (imo), WAY more comfy, even the bag it comes with feels nicer than the HE-400's. I'll play with these on my Odac and Magni for the next few days and I'll come to the conclusion that's been driving me nuts for the past couple months.
