Headphoneus Supremus
The PS 1 is enhanced in low and super hi and poorest in the medium, not neutral as the incredible HP2 (especially the edited by Joseph ...). The PS 1 is not made by the old Joseph that for me remains the only major manufacturer able. If you want a headset exalted for the pleasure of listening to some music, take the PS one, but if you want the ultimate in accuracy and consistency take the HP2!
