Don't go by graphs, don't go by reviews, or the words of others... Trust in your own ears... No the PS 500s or not like other Grado's, nor were they ever supposed to be... And for that reason Grado lovers either love them, or hate them...There are no in between's with this model.. I've had my PST 500s for a month now they are burned in now, so I can finally hear them away I'm supposed to hear them. In the past I've owned a pair of SR 60s As well as a pair of SR 80s and at present I still own a pair of RS 2's. The Sr60 as well as the SR80's headphones were and are excellent buys for the money and each brought me many hours of enjoyment, but it wasn't until I listened to the RS2's that I really began to find what I was looking for in a headphone.. At that point I guess I was planning on sticking with the RS2's until either they or I died, whichever came first.. Unfortunately at that point I had an opportunity to purchase a pair of open box PS500's for an exceptional price so I figured I would give it a try he would they would like and later on I could always sell them for at least as much as I paid for them. In the past whenever I had talked to other people about these headphones they always told me the same thing. The PS500's sound muddy.. Look at the graphs...Stick with the RS2's or if you want to move up try the RS 1's...
After having these headphones for a month all I can say is I'm happy to report that, I am happy that it did not listen to the people advised me against these headphones. I like the richness and the warmth that I hear from these headphones I like the fact that there are little darker and sound a little different from the other Grado's . My RS2's have become the headphones that I use at work I bring with me on out of town trips but it home my PS 500 are my babies....
