The AKG's seem to split the difference between the forward in your face Grado Sound and the Relaxed, Open Sennheiser sound.
For what WE do mostly I would consider the Sennheiser Cans with an amp that has an available crossfeed filter.
As always, what floats your boat is what's most important. Buy some AKG's to try and borrow some Sennheisers for comparison as they're much more common. Most folks give you 30 days as a return policy...
