Some reviews of other bags have warned about rips when cargo moves within the bag. Life changer! It works great, very clear. The ear pads are extremely comfortable, but as an audiophile I do feel a slight change in sound. Thus the four star rating. Works on my Samsung S9 + which its a big phone. 50% des Produktpreises selbst! My daughters have trouble with their skin too and I told them I would try this for a week and be the guinea pig before I bought this for them. Does not seem like it would scratch the bicycle because the ends are rubber coated. I?m happy with my choice !
