I have known that SEINNHEISER helmets and SONY and GRADO, I do not think so much AKG and Shure, I went ahead with the purchase of the 598 that after lengthy readings test.Pour now without grinding, these headphones Sennheiser 598 connected to a small dac NU FORCE plugged into my computer, gives a warm reproduction, but not artificial, very precise, airy, and rediscovers all his pieces musique.Sa ability to separate instruments each other is excellent, the different musical planes differ significantly, especially when listening to a classical orchestra with different groups instrumentaux.Le jazz and pop are not standing still and is then carried out between the instrument response they and their voice of support. Very good highs and mids, but the bass rather round are not very pronounced. Very well controlled distortion, or in acute infrabass extréme. Over time, it feels like same a certain lack in bass, the very accurate music reproduction is quite dry, we would like a more "fat" Okay comfort, but the ears a little warm when same despite the great comfort of contention. The reviews on this helmet "open" sound exaggerated, well on your neighbor, close to you, can slightly hear what you hear, but you are not annoying to those around you, and you can hear the cat meowing for its croquettes or the ringing of the front door. We can only say that this is not a helmet for walking out. Finally, concerning the aesthetics everyone's tastes, in my case, it was rather disappointed, very plastic helmet yellowish, yellowish I mean, not like the publicity photos Finally congratulations AMAZON, ultra fast delivery.
