While they will sound great like the 7506 its not gonna blow you away for casual music listening. Now what doesn't help with closed headphones is they need to make a tight seal with your ears so many experience "clamping" sensations and other comfort issues which can also detract from the experience. Well designed open headphones like many of the open circumaural designs have a more well open, airy and natural sound characteristics as well as being more comfortable. There are exceptions of course.

I agree with the doc on this. I only use closed headphones for when I’m flying on my plane otherwise I couldn’t hear anything. OTOH when I was trying out headphones I instantly knew that I preferred open to closed when listening in quieter environments. Plus the circumaural have always felt more natural and comfortable to me.
