Shure EACYF1 6L

These used to be great with perfect isolation, until Shure decided it was time to "improve" and handed off the manufacturing process to Comply. The size large is certainly no longer large but more like small, they no longer provide any isolation at all for me because the physical size has become too small. The material has also changed to the kind of dry foam that Comply uses which usually don't last as long as the material Shure used to have. Terrible development, unfortunately.
