First of all, the sound is quite good.
Comfort ... Not recommended for use for movie editing, watching YouTube movies, TV-series or feature films, because wearing the headphones for a long time cause your ears to sweat and since the headphones are not of the open type, the moist get trapped inside your ears.
Also the headphone cushions are slightly too small, so it's partly on-ear and not entirely over-ear. Vulcans can fix this by twisting their ears and carefully inserting them into the headphone cushions.
If you care for your headphones like I do, they should last around 1-2 years (daily use).
The left side broke at the hinge on mine (that's because there's more stress on the left side as the cable is pulling a lot there; there's no cable pulling at the right side).
I find the length of the cable very nice; I never had issues with it being too short, tangling or any other imaginable issues.
For the price, you get some headphones that sound quite good and will last for a long time if you treat them well.
I will say that I'll probably go for 'open' and 'over ear' Beyer Dynamic next time, though.
