Pros: Sub bass, soundstage, isolation, price, build, comfort.
Cons: Can be boxy
This was my first pair of what I call real headphones, Loved them the moment I put these on my ears.
To me they have a massive soundstage (quite odd considering they are closed), big bass, and extremely comfortable. I would recommend these to anyone looking for a headphone to use with any type of electronic music. They can be powered from an iPod but sound much better with a dedicated headphone amp. The headphone amp brings a certain "energy" to these headphones that makes them really wake up. Make sure that your headphone amp if using one has a lower output impedance (less than 1 ohm) for best results on these.
