Query: lost them recently and glad I did

they sound ok, except what good it's for if earpieces constantly fall out and the head band won't stay put. And how could it be otherwise the way they are build as little speakers rigidly facing forward. I saw some reviewers claiming the opposite, but I think they got confused about the product they are reviewing, or else they have heads shaped to special Sony specifications. I finally lost them somewhere to which I could only say: good riddance.
