Pros: Lively with a great range and the lows are amazing.
Cons: Extended use makes your ears very warm and sometimes perspire.
I upgraded to these from the Sennheiser HD590s. Huge difference in the sound. The overall range and clarity sets it apart from lesser headphones. The lows it can reproduce are amazing.
It's design and look at really nice and elegant. The box they come in is very nice as well.
The only gripe I have are the leather cups retain heat from the body and can make your ears very warm over time.
