Surprised I was then but the first operation. A perfect fit, and sound quality. I am pleased it really, these also use the sport. Unfortunately, I noticed too late that these headphones seem to be 100% only for Samsung devices. I had assumed that my iPhone 5s works with it. There was also nothing to the contrary in the product description. Unfortunately works with the iPhone 5s Although the pause button, but the volume can not be controlled. That's a big fat deficit ...
The earphones have been used in sports often wet - either by sweat or rain here, I have found no adverse effects. However, I could light cable noise perceive (a slight background noise) when I was out in the open air. Was on the ergometer it but again no trace ...
+ Very good Klagqualität
+ Perfect fit for small, medium and large ears (by different essays)
+ Because of the good fit lightweight insulation of background noise
+ No slipping
+ Clothing clip, storage bag
+ Pleasant Cable length
+ Clean processing
+ No weather dependent
- Some keys do not work with the iPhone 5s ... While I can press pause, but volume up / down goes only via the mobile phone itself.
- Background noise by cable noise outdoors
+/- Frustrating packaging
+/- Gaudy color
In summary, I'm not sure what to make of the headphones. Of course it's my fault if I want to run my iPhone with it and in the product description only of Android devices is talk. Since I was probably pretty naive ... Then again, I am impressed by the good sound quality, but impaired when operating in the open air. I have now decided on 3 stars (= not bad).
