Summary: These Headphones are worth the cost. However, I think that I like the sound of Grados a little more. The Bass reproduction on the Sennheiser seems to be a little light for me. The comfort of these headphones is where I think these beat the Grados. I'm going to get a headphone amp and see how this will help improve the quality of the sound. The issue may be that I'm currently running the headphones through the headphone jack in my receiver.
