Keeps the helmet in place, very good sound for listening to sports conditions. As against the remote is heavy and serves, in my opinion, nothing. In addition, the cable is poorly thought: the first part is made to connect a short player (eg arm) and without telecomande but is unusable because too short. The 2nd part with telecomande serves extension but makes for its part, the cable too long. Makes you wonder if they really test the product with sports ... A final flaw with moyennenement comfortable headphones. In short, a good sport pure product (which seems reliable) and a good sound but poorly thought at the cable.
