Pros: Comfort, bass, 2 chords (1 x portable, 1 x desk), balanced (with a good amp)
Cons: Pads does tend to get hot.
I agree w most reviews that these does not warrant the $499 MSRP. (Then rather opt for D5k, D7k).
BUT - at the +-$230 range I got them at (Amazon warehouse) - these are VERY good value for the money.
