kruziWith HE-4XX ?? For me... they sound boring, predictable. They are not surprising. They are round, do not differentiate the quality of recordings, poor performances sound similar to good ones. HE-4XX do not reveal errors. What could be an advantage for me was a disadvantage, so I prefer the K612 Pro or M220 Pro. They sound a lot better, especially the M220 Pro with velour pads from Beyerdynamic D990.
