I'm not starting a bashing thread but just posting some thought for the newer members who missed these back in 07/08.
So many people say the M50s are the gateway into this hobby. You younger guys REALLY missed out.
These were and still are the best headphones in this range ever. The M50's can't hold a candle to them, I know the Cals are very close, but the Denons are just better sounding. Too bad Denon got rid of them, A few places still have them in Japan but they go for upwards of $200.
Not a hard call for myself to pay that for them, but at the under $100 they went for at the end, I find it very hard to be beat by anything really. I still rock mine daily!!!
