So white/silver is the newer version, and black is the older one?

Oh go play with the grandchild.

It's funny, I was checking around the HD600 measurements thread and a lot of people were saying the same thing. Now I'm debating if I want to buy a pair of $60-$70 pads for a classic, but cheap backup headphone. Hmm, decisions, decisions...might be an excuse to switch to an HD650. My ears are super sensitive to that 3K-4K boost/peak, I was able to learn. Since I bought mine used, now I'm paranoid that I've always been hearing it with the peak.

You can buy the HD650 drivers for around $90 a pair and install them in the HD600 frame. It's easy to do, no tools required except maybe a guitar pick, but it takes a few minutes which means you can't quickly switch them to compare. (Maybe switch one driver and compare the L/R?)

I put HD650 drivers and grills in my HD580. I honestly am not sure how different they sound. Whatever the differences are, they are small in comparison to the difference between the and other phones I had at the time. (HP50, Paradox.)

Now, the above little tirade about community literacy is not the definitive reason to buy/acquire/sample the HD600. It is actually sounds very good and performs very well. Even after I got the HD800, which have dominated my ears in the last few months, I regularly put the HD600 back on, and remember "oh yeah..."

Agree. Have heard most of the ultra uber headphones, own some of them. I still enjoy the HD600 with BH Crack several evenings each week. The HD600 is my goto can for voiceover editing, though I use it then with a V800 / V200 combination.

Not exactly about the HD600, but you guys might find this interesting. I'd comission one in a heartbeat if I had a pair.
