Just a couple tips for prospective buyers:
I once purchased the HD580s and must have got a bad unit (returned it) as there was a substantial difference between the sound levels of the two drivers. My point is that the 580s don't have matched drivers so the sound may differ slightly between the two drivers though it's probably not usually noticeable. If you wan't matched drivers and a stiffer frame with an overall better sound, save up for the HD600s. I read that the 600 is built to a 1dB tolerance as opposed to the 580's 3dB. About 3 dB is about double the perceived loudness when measuring sound levels but this may not be a good analogy. The 600s are built with a stiffer carbon fiber frame than the plastic cased 580s that is said to improve the sound. They sound better to me than the 580s and I like the build quality better.
I waited for years and finally got the 600s and added an HD650 cord. It's been just what I was looking for and I don't even use an amp. My thinking was that since I planned to use them daily for decades, why not save up the $250 or so for the 600s. Amazingly, I haven't become a "can collector" as some audiophiles warn you will become mostly 'cause I'm a frugal type person. The 600s have done well with every kind of music I've tried from rock to classical and new age with plenty of bass. I bet the 580s would be a good compromise though for half the price. I'd recommend the 600's if you can wait and save about $125 more. Keep in mind you also are advised to replace the ear cushions every few years depending on usage rate for hygienic reasons and wear. The improved replacement HD650 cord is only about $11.00 from SennheiserUSA with very reasonable shipping and a good improvement for both the 580s and 600s.
HD650 Cord Linked Note it only has a 1/4" plug so you may need an adapter (Part # 92595 Nice 1/4" to 1/8" adapter at same store but not linkable, sorry)
To get the 600s for $250 shipped may be difficult as
JR.com no longer seems to have them! What's up with that? They say the 650s are replacing the 600s which is a thoroughly bad idea as most audio enthusiasts will concur. The 650s aren't as natural sounding and very different headphones with a forced bass heavy sound, and the consumer wants choices.. Wow, Sennheiser if you read this
please don't cancel the HD600s! First the superb Sony MDR-V6 disappears for the less than stellar V600s and now this.. I just can't believe it. Please someone tell me it's not happening. If it is, I'd advise saving the $270 or so to get the HD600s from Amazon or somewhere before they disappear if they are indeed going away. Extremely bad idea Sennheiser! :Q
