After a month of intensive use in the gym, I can say that the CX full justice 685er my requirements: Whether in the exercises on the equipment or - much more important, because for that I bought it mainly - while jogging on the treadmill, sit headphones bombproof. The sound is great and the outside noise are ideal shielded (previously I have had unfortunately too easily distracted while running from the often very loud music in the studio). I particularly like the beautiful, rich bass - the music I hear in sports, also requires it.
The often criticized in other reviews I have cable noise perceived at rest before I have attached the clip on the collar. When Sport itself I did not notice any disturbing noises.
The cables make a very strong impression, which is very important to me; Finally, because often times turn "rumgezuppelt" during sports. The cleaning simply under the tap I find enjoyable and practical.
A small downer remains: the fact that the straps are adjustable, I have apparently sometimes incorrectly adjusted, which then manifests itself after a while by a slight pressure pain. Well - maybe I just "problem ears", and the pain disappearing fast even after a small adjustment, but for this reason I have to just pull off a star.
Otherwise: Great product that I have already recommended!
