Not to run

My goal is to find a wireless sports headphones.
Seeing the description it sounded good.
In use it is another thing:
- First record indicates that you should not wet the helmet and he fears humidity, this is different from the description and fears for intensive use in external conditions
- Then there were 4 tips to adapt to the ear, except one small and three means (sorry I have 2 ears)
- Walking it will have less, without proper quality and it just keeps
- Running outdoors that was the cata
In short I returned inconclusive because it does not at all correspond to my expectations. I expect repayment and probably invest some more.
If rapid delivery by the parcel is against a slightly smaller envelope (cheap therefore normal delivery).
