I've recommended the ATH-M50s time and time again. My original pair (bought in 2008) was outstanding. I couldn't be happier. I picked up four more sets recently and they are NOT the same. They are dramatically darker sounding and not as deeper either. One of the sets was DOA, although sometimes shit happens.
I noticed that the cord has changed from the coiled type to the straight type, if that helps you.
So it looks like I'll have to make a new headphone recommendation.
