sr325 originals owner here.
They are quirky, but, they feel as expensive as they sound, and when a wire detatched inside the right can, i could easily pull the barrel apart and fix it, also, fix both sides so the wire would never come loose again.
The thing is, where can you just snag a hand made american headphone like that? Grado does not sell a LOT of phones, but the ones they do get passed around and cherished. Mine were bought from someone that went out of his way to take care of them because, well, they just felt more like a way to connect to certain music and it's roots than some mass market, even really good mass market headphones. Get passed the 325s and no two pairs are alike. Find an original set by Joe Grado, and you are not just listening to music, you are sitting down with it and chilling out, getting to know it, maybe over some coffee. They obviously sound good enough for people to go far out of their way to care for their sets, even if they don't like them. For me, I just like the fact that, like some gooood whisky, a good pair of Grados is something from the US that is, at least, given respect around the world. That is something rare. Every other good set I own is German. I am guessing one cannot take a step in Germany without tripping over a really good pair of headphones. I just like the DIY roots of Grados, but within the world of good headphones, they are just one of many. That's cool. I think my DT880s are too nice to take apart. My k271 originals, oddly, use the same EQ settings on the parametric EQ as my sr325s. The k271s had a good studio run. What does that say about the Grados?
EDIT: I am aware that my akgs are from Austria. I was thinking of precise German engineering, which, I quite respect, as a structural designer.
