After I had bought myself a wireless Stereohaedset, I followed the recommendation of the assessment of Haedsets and have ordered these Ohrpuscheln. Here are my expectations were not met (at the not inconsiderable price). Positives: the foam bodies adapt very well to the ear canal, outside noise is almost imperceptible (on the bike unfortunately not so good) Negative: strong vibrations (Holperpflaster, curb, etc.) transmitted interfere as muffled sound. Depending on the intended use conditional purchase recommendation.
