Processing: Already here a lot has changed, the built plastic looks significantly high. The matt surface causes a lot here. The buttons are made of rubber, which feels very robust and ready. The tactile feedback of the buttons is well chosen and there is a bump on the middle button, so that the operation is possible even blind.
The cable is made of rubber, and slightly grooved. A quality image, whether it is also will be seen in daily use.
Accessories: As usual with in-ears come up with here also 3 different large Aufätze, as well as a clip holder that can be fastened to the cable.. Add to that a small pocket for storing the headphones.
Optics: The principle of headphones unfortunately prevents a sleek appearance because of "pull" wing needs naturally place the headphones as its predecessor are very clunky. In sports, I do not think it is not important, but in public, pulling the headphones thanks to the size and color but some attention. As stated above, however, the material looks very high. The color is a matter of taste, I like it.
Wearing feeling: I have in-ears to really keep in general problems in the ear, playing sports, of course, more. But the principle of Sennheiser I find great, it is necessary a madness stop without pushing or pulling unpleasant, and it can be individually adapted to the ear size. I already had other headphones (eg the Sounpeats QY7), where you could replace the wings, which I did not like as much as this solution. Even after extended wearing, whether in normal use or during sports, I feel wearing still very pleasant. From experience with the predecessor was clear to me that you only have to enter some headphones to start the rubber acts a bit stiff and not fit to 100% to his ear, but the sets over time.
Here, let me tell you that it is a subjective assessment, everyone has different ears what is so perfect for me, does not necessarily have to be suitable for you!
Sound: How Sennheiser usual really good. Unlike its predecessor, here the focus was a bit more laid on the bass, which really is very impressive, relatively full pressure with a good fullness in sound. However, treble and midrange are not forgotten. All in all I am very pleased with the headphones.
Conclusion: 60 is a steep price, where there are already wireless for 30. You get here better sound for your money? Yes, but that does not justify 30 ... rather it is the total package. The build quality is top, my last Sennheiser keep still. They are waterproof, sweat can be easily washed off so. The comfort is (at least for me) absolutely awesome.
One can be happy, whoever is not with cheaper headphones, should definitely try out the Sennheiser. From me there are 5 star.
