Personally I recommend the Stax SR-009 electrostatic headphones.
Frequency Response: 5 - 42,000Hz
Sound Pressure Sensitivity: 101dB / 100V r.m.s. 1 kHz
Maximum Sound Pressure: 118dB / 400Hz
Can't argue with those figures. Since they are electrostatic and require quite high voltage bias (580V), you'll need to buy the special preamp.
