Promising review: "I purchased these earplugs because I suffer from something called annoying neighbors syndrome. I would liken the sounds coming from below and across from my apartment to that of an auto shop or a construction site, perhaps even an airplane hanger. Therefore, I have resulted to earplugs to ensure I get a somewhat worthwhile night of sleep. The contour capabilities of these ear plugs make them incredibly comfortable to wear. After inserting the earplugs and allowing them to adjust, silence befell my bedroom. I was able to sleep free from the obnoxious noises that surround my apartment. These will be the only earplugs I wear from now on." —Emily Buss
