I have a question about my older pair of 650's. I have had these for about 7-8 years now
and they have the older dark colored drivers. Has anyone updated their headphones
to the new light colored driver and was there any appreciable difference?
Another question. Has anyone tried the HD-600 drivers? I just wanted to try
something different possibly.
