Does the job, but falls out too easily
Filters out noise well. My apartment has noisy neighbors and these plugs shut out the noise well. They need to be pushed in til you feel a seal in your ear, otherwise they are of no use. Also have fallen out of my ear during sleep and can get lost easily under bed or on floor. Little rubber seal also came out, which was annoying to find and replace. But when in place, these plugs do a fine job of cancelling noise for sleeping.
