If I could make one comment. I have owned the Grado SR-80 hp for at least 10 years it seems like. I used them for listening in my cube at work. After our hose burnt down in a forest fire I went on a search for a new pair of cans. I listened to a lot of them and ended up with the Grado 325, brand new shinny ones. The difference between the 80's and the 325's are night and day. The 325's are so nice and really is a work of art and feels very good in the hand. The mid range is better and the bass is very improved from the 80's. It was a breath of fresh air getting the 325. But my work has changed and I can no longer use an open backed headphone at work. Luckily I do not have to drive in there too often. But I will be selling my 325's and will be getting the Alpha Dogs closed back so I do not bother my cubical neighbors. Don't get me wrong, the 325's are far superior than the 80 and the 80's are very nice. I just think that the 325 is so much more of a headphone that there is no comparison.
