Well, after receiving my email, Head-Direct sent me a new cable and velour earpads. I was told I was also going to receive the retail box, but that was not sent.
The cable I received is different from the original, it is terminated with a 1/8 plug with a 1/4 adapter included. The "leather" ear pads have also changed, and have a more dense material separating your ear from the driver (you cannot see the driver through it). I prefer the velour pads, as the material on them is not as dense (you can see the driver through it).
After initial listening, I don't know what to think. These don't sound like the HE-400's I had before. The bass impact (punch) that was present in the first pair is nowhere to be found. This was the main reason I decided to keep the HE-400 along with my HD800's.
Is my memory really playing tricks on me? Did anyone else from the first batch notice a change in sound?
