I think GTM intended to point at the fun people were having. The point got lost!?
Anyway, here is a serious micro review of Sennheiser HD800.
It sounds much more relaxed than 650, the model it is supposed to improve upon, but loses on the low level micro details. Highs are more extended and it sounds fuller. Mid-range veil is also lifted. It is also easier to drive compared to 650.
Would I buy it? Yes, if I never owned a Senn and want to add one to my collection. No, if I have a Denon AH-D5000 selling in a nearby store.
