When I was at the store auditioning both the MD with shure pads and dog pads, I honestly had to sat down and think really long before finally made my purchase. I was one of those people who thought the shure one was bass light. After comparing the two, they are of two different sonic characters. I like th dog pads bass response, on the other hand I also love the midrange and the highrange character of the shure ones. I did understand that it's a give and take situation, so I went for the dog pads because I think they're more comfortable.
I also thought getting a pair of shure pads for replacement is much easier here than to import the dog pads. Haha! But I have to say that I'm happy with my purchase.
