I guess they are very aware that this is a weak point in their design. I bought them for my University daughter with limited space in her apartment. The raised nodules in the sole inset provide a mild massage action. I think these may have been knock offs. The price was just right. I wore other the other pairs out. Even so, the right earpiece now seals properly in my ear, and the sound is sublime. Let?s hope it stays there, any thing like the command picture hanging strips and it?ll be just fine. Peace of mind with Thule knowing it is the best. Bought a Beats pill+ and the sound is so much better.
