I have bought this helmet because he was recommended for the sport result after test .... it is very comfortable to wear, it just smells and it's true that it fits comfortably on the head, most headphones are washable which is a big advantage for this type of helmet. As against this helmet is not without drawbacks: First the sound is feeble and somewhat metallic, bass are not great either, my old headphones Koss PortaPro done better, then we do not isolate noise outside ... it can be an advantage when one is outside but when you do cardio in room no interest. Another disadvantage so it does not bend therefore provide a storage space in sports bag.
