Switching between low/high (2.5/6.5x) gain on my O2, I notice a clear difference in sound. In high gain they sound fuller, more "body" in lack of another word. Sadly there is bass distortion in bass heavy music, but the parts that is clean sounds quite, eum, interesting? Different if nothing...

  The lenght itself I dont see as a problem, rather the opposite. Gives a bit more freedom, and thats never a bad thing! The fit of the cans are so good as the weight of the cable doesnt bother me either. But yea, a bit on the thicker side... And it being a "twin cable", instead of a single...

Took a while, but yesterday I finally got a chance to demo the Elear. Paired with a Moon 230, as that was the most neutral one they had set up in the shop. They felt a bit weird when I first put them on, compared to my AKG K712's the clamping was much tighter. But that was quickly forgotten...
