Out of curiosity, I put in a bid for some interesting looking headphones on ebay, the Sennheiser HD 540 Reference Gold. They have gold plated trim and come in a pretty wooden box. Earpads were pleather and I basically had to remove all the pleather junk cause it was flaky. Here is a link to a pic: http://imagehost.auctionwatch.com/bi...eadphones1.jpg
They came today and are very interesting indeed. They appear to have been made in 1987 and came with the original owners manual, warranty card (I think the 2 year warranty has expired), and a certificate with the serial number and Dr. J. Sennheiser's signature stamped on it. Pretty complete package, I'd say...
The cans are plastic with a pleather/vinyl appearing headband with the model and serial number again stamped on it in gold. They are circumaural with a gold band between the earpads and the earcup. They are open headphones with horizontal open lines forming a grill on the outer earcups, there is gold foil material inside the grill. Other than the gold plating everywhere, they seem cheaply constructed of plastic and are fairly light, though comfortable to wear. The 3 meter cord connects to both earpieces (removable) and is rather thin, terminating in a 1/4" gold plated plug with a nice golden "spring" at the cord's entrance to the plug to keep it from bending too acutely.
Anyway, I'm curious about the history behind these. I haven't yet heard them as I don't have any source/amp with a 1/4" jack and I don't think I have anything that can really drive them anyway, here are the tech specs from the manual:
Frequency response: 16 to 32,000 Hz
Rated Impedance: 600 Ohms!
Sensitivity: 94 dB
Weight (without cable): 250 g
I could be wrong, but that seems like a pretty high impedance...
So, if you have any comments or knowledge about these cans, please let me know. When I get a chance to actually hear them, I will report back, though my ears are not finely tuned as those of an audiophile. I can at least compare them to V6 and HP890. I also hope to take more pics soon.
