Performance good, but unfortunately not for long!

I initially had problems with the sound, mainly because the bass was missing. There is but the many essays and fits. One really has to push the headphones far into the ear, in order to achieve a good sound. These are my first InEars, but I have got used to it quickly. After sitting a week or two and getting used to keep the InEars even much better in the ear as normal headphones (such as the Apple).
Positive are also the knob to adjust the volume as well as the supplied bag.

But what most annoys me about these headphones: They are after 6 months already broken! My left listeners no longer works, the right scratching constantly. This is not only with me like that. Two friends, who bought the headphones at the same time as I, have the allergleiche problem. That is not because I badly Bypass with headphones. I have indeed every day there, but have from the outset been careful not to pull on or otherwise damaging them somehow. And yet they have held less than six months. The Sennheiser Support sends repair request the headphones due to "own fault" back.

The first 6 months have been fun, but I will not buy me 2x in my new headphones for 40. I rise to a different brand.
