Thinking about buying an Ultrasone.
Either DJ1 PRO, PRO 550 or HFI 2400. They all cost about the same.
Does the DJ1 PRO use the same drivers as the PRO 550? I know the HFI 2400 is an open headphone and sounds different but does it sound "better"? Would you prefer it over the other two? Why - why not?
The PRO 550 I'm talking about are the v2 ones (white/silver/black). What has been changed on that one?
