Ask Slashdot : Best Headphones, Earbuds, Earphones...etc?

Some features of these that would be stupendous to have (descending order of importance) : Noise Isolation (Not cancellation), flat/near flat response (I need to be able to hear bass, but I don't need my eardrums blown. I'm looking at you, Beats by Dr. Dre), Long-term comfort (Earbuds usually hurt for me), Durability. Over-ear is preferred to anything on- or in-ear. Boom mics are permissible, as it could very well see time as a broadcast intercom headset.
