electrostats have generally better detail and speed, they dont muddy up the sound no matter how much/fast the signal coming through. the one big advantage of a dynamic is in potential bass, a dunamic can move a lot of air and give a big bass boom or thump.
modern high end dynamics are a lot closer to 'stats than they used to be. back in the 70s, 'stats were far beyond the clarity of any dynamic
keep in mind my electrostat experience is limited, but i have had a ton of dynamics and a few orthos (even one piezo!)
maybe both, but the O2 is said to have that plenty bass.
I was pleasantly surprised by the HE60 after all the descriptions I'd read. Not even close to a proper bass monster but very satisfying sound nonetheless. Great extension both ways, it's all just there.
That's the main difference to me, 'just there' sound against 'put there' sound.
O2's have the best bass I have ever heard from a headphone, natural, precise, musical, articulate and with great impact. However if you are into artificial and exaggerated bass (bass head) they are not for you
the push-pull electrostatic motor is generally more linear than the PM/voice coil motor of dynamics and gives lower distortion - at least in charge control operation
also the electrostatic diaphragm is orders of magnitude lighter - to the point that air damping effectively suppresses the multiple mechanical modes that plague edge driven stiff radiators in dynamic cans at higher frequencies
lower displacement range however limits electrostatic SPL capability at lower frequencies compared to dynamics

It's tough to get a sub that's quick enough to keep up with an electrostat. You usually have to go with a servo or other exotica. Otherwise, the sub won't integrate well and you'll notice the difference in phasing. Martin Logan made a one-off electrostatic subwoofer once. IIRC, it was the size of a sliding glass door and had some ridiculous amount of voltage (like 20kV) on the stators. I don't even want to think about it arcing.
As to the OP, electrostats give you a much faster transient response. The diaphragm is damn close to a massless driver - that's the ideal. You get some spring resonances because the diaphragm is tensioned, though. If you want near massless without the tension, a ribbon or AMT delivers. A few lunatics (whom I admire
) have built ribbon headphones and Ergo makes an AMT. I've had a passion for ribbons and built a pair of ribbon speakers, so I'll eventually build a pair of ribbon headphones.
