Before that, the previous model 3570 looked exactly the same as the 3590, I am very pleased with them, they worked for exactly 1.5 years (the right ear failed), unlike other headphones that I had, this is the best result for this price. Over time, the wire does not lose its softness, which made me very happy! 3590 seems to be more bassy, I want to change the equalizer settings, I can’t get used to it, I tuned it to the 3570 model, Icomuldn’t get used to it either :) I like full bass and treble and the middle is at zero. I found a review, there the pros say they have really good ears
