2, high-frequency sound quality is different:

The second generation of Sennheiser buns of high-frequency details in the price of medium, medium in permeability, medium in flute performance, medium in dentures. Same price, medium soundstage, medium dynamics. Separation medium, resolution medium, transient medium. Compared to the first generation, the second generation is easier to fold and carry. Larger earcups, more comfortable to wear. Different appearance, improved low frequency, clearer details.

This is a very noticeable improvement in vocal control and instrumental playing. This is a good headphone. The previous generation of headphones was more focused on sound details.
