So I picked up a used pair of Sennheiser HD555's that had a small crack in the plastic. I took them apart to repair the crack with some CA glue.
Since I had the HD555's open, I figure I'd snap some pictures.. I'm hoping someone out there will open up a pair of HD595's so we can ACTUALLY see what the difference is in hopes of either coming up with mods to turn HD555's into HD595's. Or if there is no difference, so we can save people lots of money. I'd also be interested in seeing some pictures from the HD515's.
The pictures are here:
Index of /dump/hd555
I suppose the obvious difference could be drivers, but I've read that the drivers are exactly the same. Maybe we can confirm/disprove this? But I also can't picture a manufacturer making 3 different types of drivers that look EXACTLY the same, but some purposely made "Worse" to put into lower priced headphones. Especially considering it would probably cost a manufacturer exactly the same amount of money to make good drivers or not-as-good drivers.
Oh yeah, it's also worth noting that Sennheiser's "special internal Surround Reflector, which generates an extended spatial sound field" doesn't actually seem to exist. I think people think that it's the lump that's near the edge of the inside of the headphone, but that's only there because the plastic joint is behind that area... which is pretty obvious once you take them apart. Maybe the internal sound reflector is the piece of black foam that's badly glued onto the inside of the grated vent on the backs?
I'd also be curious if anyone has ever done a tear-down comparison between some of the Grado headphone models...
