I have to agree with the consensus on whats been said about the HF2. I spent a lot of time with Headphone addicts HF2's on sunday. I was listening to it from my zune and nuforce icon mobile on high gain.
I definately was blown away. The bass impact was definately more than i was expecting so punchy but not overwhelming. The electric guitar soared with no shrillness or sibilance. The mids were perfect, i was right there in the front row, the cans were so involving i had a hard time not acting stupid while in the ttvj room.
It did everything well and was way more comfortable than almost any other grado i tried that day except for the PS-1000. The Headband definately has more padding and i am not sure what pads were on the cads because i dont think they were stock. But i am almost certainly getting a pair of these headphones...
