I have the 3 studios, but not the others. Some thoughts....
Great highs, clear, extended bass. HOWEVER, the bass has NO kick. Its like a munchkin attacking a giraffe, but when a synth or low strings play the bass sounds big and smooth. If you like rock music, for god's sake stay away. The clear highs will expose the badly recorded rock guitar, which will scrape its nails across the chalkboard. If you like jazz and classical, these are great! And they isolate pretty well, too.
The replaceable cables are a MUST for me. In fact, yesterday I was biking to work and my headphones fell out and got caught in my bike chain. To my horror, the wheel made a full turn, trapping my $120 headphones between the chain and metal teeth thing. I carefully removed them, and there wasn't even a DENT or scratch. These cables are thick and well made, AND replaceable.
They stick WAAY out of your ears. Do you sleep with your earphones? Then run far, far away from these. And the microphonics aren't great, no matter how you wear them. They block WIND well, which is great for biking. But not rubbing on your clothes.
I\They are good, but i'm not satisfied.
