Very comfortable headset. My favorite features are:
1. Detachable spiral cable. As for me - this cable is great - sturdy (I have had another headset for over two years with a similar cable type - AKG K-712 Pro - no problems for everyday use for 4+ hours in a row so far). Easy to organize (spiral cables don't need to be untangled, while straight cables do). Finally, the length is just about right.
2. Velour cushions. There are two pairs of cushions in the box - the default ones (soft man-made leather) on the headset, and velour ones as a spare pair. Velour cushions are awesome! Having them is a great life-saver as the headset sits nice and soft on the head and it doesn't feel uncomfortable wearing the headset for a long time.
One thing, however, that makes the overall impression a little bit fuzzy is the headband. It's made of some sort of PVA material or something, and it does look a little bit strange (cheap? weak?) for a headset for everyday use, which costs almost €300. The headband of my AKG K-712 Pro would be a better choice in this particular case.
