First off, I love the maddogs. But they are closer to the 650 than to the 880's. They are well balanced with a nice touch of warmth with the dogpadz. In fairness I'd call the dt880 on the bright side.
Perhaps if you ordered with the shure pads they would suit you better. I only have the dogpadz version so maybe someone else can comment on the other version.
I'll grant the 880s are on the bright side .... to my ears HD650 are too dark.... ideally I like FR midway between HD650 & DT880. Probably difficult question for someone else to answer for me, but am I hearing a red light? I probably won't appreciate the MDs?
