This is accurate. The he400 also has a treble spike around the 10hz shelf that some find annoying. The he400 is a good hp...very open and spacious sounding, good instrument separation and great textured bass. I'd still take the MD all day even if they were the same price.
After listening to your headphones this weekend, I have to agree. This was also my first time listening to the he400s as well. I was impressed by how good they sounded for the price and believed them to be a good value, but I was more impressed by your md's. I liked them better than the lcd-2, and the fact that they're closed is even more impressive; really loved the pads.
