This headphone is the perfect choice for any budget oriented audiophile. They last for decades if you treat them right, you can switch to velour pads for extra comfort. Plug them through any amp for extra juice and use some EQ and you will get sound that is worth three times what the sony's cost. I auditioned the shures, and the headfi favorite m50 and to be honest, I couldn't get what all the hype was all about. Many like to say that it is an outdated headphone (been around since the 80's I think) and that there is better technology out there etc etc.
I will just say this, the 7506 is never leaving my house, and many other more expensive headphones have come and gone. We all hear differently and ymmv.
