For me, the problem with the weight isn't that it's hard for the neck to support it or something like that, it's just that the weight is hard on the skull.
This can be fixed by changing the headband, once that's done, they are not to heavy anymore.
With all respect guys, but this, an review, are you joking me? http://www.enjoythemusic.com/magazine/equipment/1012/grado_ps1000.htm
Is it a good or useful review? No.
But I think it's a bit fun and it's definitely appropriate to post something like that in an appreciation thread.
I think most people here is intelligent enough to take it for what it is.
