Overall disappointing 1

Have bought the headphones for jogging because I thought that a) adidas its expertise for sports fitness has incorporated and b) the name Sennheiser promises good sound and quality.
Unfortunately, I was disappointed on both counts.
The headset sits with the rubber stopper in the ear very well - as long as one does not move. No matter which of the 3 sizes of plugs I try, with all the falls of headphones while running from the ear, so I constantly have to push in the handset. OK, on ​​Apple earbuds original that was worse, particularly in the newer version smooth. Still, I would have expected from a headset with earhook Adidas far better fit.
To the sound, I can not say anything negative. Rich bass I do not expect from an in-ear Earphones anyway. In any case, it sounds better than the Apple In-Ears.
However, I think the strong attenuation of ambient noise for hazardous in case of sports headphones. I would like to see more often that I would learn in more cars or cyclists when I cross a street while jogging.
Last and biggest gripe is the durability. After 1.5 years, not very intensive use of headphones falls almost apart. The rubber stopper no longer remain safely put on the headphones. A I have already lost. The terminal, which is infected only on cable, I have already lost while running, but recovered. The bracket both have disengaged from the headphone housing and no longer hold in spite of various adhesion tests. The small Sennheiser logo is already fallen. The soft plastic strap of yellows slowly.
Conclusion: For the price (69) and the two big names, I clearly expected better and can specifically say not buy recommendation for joggers.
