I am disabled, on my computer constantly, am an audiophile and have been collecting headphones (22 at last count). The lowest price I have ever seen on these is $349.00. Most of the time it is $449.00. If that etailer could sell them for that and make money, we should be able to strike a deal with Sennheiser. Show them the results of the AKG 7xx. Avoid the 600s. The HD 598s sound as good and you can get them everyday for $200.
