Query: not for small ears

I have smallish ears and ear canals and can't use these things. I'd had a set of MX-75 for 1.5 years which were a decent fit , good sound quality and good for workouts as sweat didn't seal them as all other buds I'd tried did. The 75's were retired when the wires had broken right outside the plug, the self-tangling cords were an irritant, too much twist, too sticky! but they had survived ~500 uses. So I'd assumed that these would have the same size transducer cage and roughly the same fit , but apparently not. the OMX-70s have a larger metal cage and won't go into my ear properly even with the ear clip's rotation, extension and springiness . Phooey!
