Can only agree with the previous speakers. The contact does not break off permanently in my opinion, is because the plugs 5 hundredths mm oversize have (6.35mm instead 6.3mm) Strange but that is when a pair of headphones to the 100 class buys always adapter receives the never fit properly. Finally, I can my considerable collection adapter on two (Have the same manufacturer also 3.5mm jack socket to 6.35) reduce Adapter.
