Hi, @Sennheiser I would like to know more about the difference between IE 80 and IE 80s. I am testing both, they where purchased one after another. The first one for me and the second one for my wife, and I feel the bass is the IE 80 S is discreet in comparation with IE 80. 80 S with maximum bass setting (with the knots) doesn’t has the bass which it has te 80 with medium bass setting, 80 s is clearer in highs. Is this right ? I am asking you because I couldn’t found any infos regarding the sound difference but I notice some.
