After listening to the HD600 for a night, it has changed my perspective on the whole hi-fi / audiophile industry. It mainly stems from my firm belief that the HD600's sound almost in every way better (for me) than the HD650's. At very best I would just call them different headphones, both with completely different qualities. The HD650's were just too dark for the music types I listen to (most forms of Rock) but the HD600's neutrality and balance are just perfect for my tastes. But if they're just simply different headphones, why does one cost $100 more than the other? Comparing the two side by side it isn't like one of the sets are better built than the other. If anything the cable is of a different quality however (with the HD650 cables being a bit beefier) that is definitely not something worth $100 extra at all*. These two very important headphone models in the current scene represent a completely effective and rather obvious marketing tactic in which Sennheiser is essentially making free profit from a headphone that is just "different" and doesn't cost much more to make but they added 50 to the model name and suddenly people with disposable income are willing to dish out an extra bill for whatever reasons. I am sure that this is not an issue that is exclusive to the headphone scene but is universal to the world as people are always inclined to pay more attention to the newest models as people want the best possible product even when in truth, it might just be a different product.
Sorry to go on a rant on you guys but I am just shocked at how much more I enjoy an older, cheaper, and to many an inferior model as opposed to the current flagship. I remember exactly why I initially started with the HD650, and I'll even admit it that it was for the prestige and elite qualities that for some reason come with owning the flagship model. However this whole experience has taught me not to chase model numbers and prices, but the sound that I truly enjoy.
*Both impressions were made on the same custom Canare cable.
Gosh, if only SOMEONE here would have said something...
[j.k. Sorry, I've been ranting about this for a while. Nice to have someone else saying the same thing. People just assume that because they are "50" more and cost more, the HD650s must be better...]
