Query: Sony blew it with the MDR line

This is the second set of headphones I've tried in the Sony MDR line, as I previously tried their 970RK model and sent them back for a refund due to distorted audio. Thinking I just got a bad pair, I tried another set, the 925RK. Same result. The audio is distorted across the entire frequency spectrum and has a 'hallow' sound (that I might be able to live with without the distortion). I doubt I got a second defective set, though it is possible. I think it more likely Sony blew it with their MDR line. How these headphones got so many positive reviews I can only attribute to my experience with high-end audio equipment and having a more critical ear. However, they are distorted so bad that even the average user should notice.
