A member here thinks they are as good as the HD595.
Each earpiece on the PC 360 has a frequency response of 15-28,000Hz with an impedance of 50 Ohms. Sound Pressure Level is rated at 112dB. (The older PC 350 is 10-26,000Hz, 150ohms, 108dB.
reading a lot on forums now about the HD555's vs the PC350 and how the HD555 is just superior.
