Worse than before ... 1

I had old earphone MX 35 of the same brand and I had to buy the new listener because the rubber surrounding the cables was eventually crack over time. Too bad ...
The sound the MX 375 is much worse than the previous. It remains all times better than other competing brands, but they are less than previous fishing and the bass is a bit too present.
Same for the ear which hurt my ear cartilage because they rub down (where the elongated portion is located) while previous never irritated me.
I am therefore of the view of many buyers here (who left their opinion): Sennheiser overall decline in quality, well mostly on well priced products such as headphones for mp3.
