Hearos 5064 Multi-Use Silicone Series Ear Plugs (NRR 21) (6 Pairs)

The adult size ran out. I ordered like 30 packs of these kid size, which is the same except the color. The tackiness (Stickiness) is superior than many other brands that the silicon can be used many times over. The trick to get it right is to roll them into a ball with the palms of your hands, then insert it into your ears with your index finger while turning clockwise like turning a screwdriver. This technique makes sure the earplug will stick especially while sleeping. I've acquired this trick over many years of usage. Good Stuff but pity they stopped production already...

these were terrible! too small and fell apart when I put them across my ear. I am sticking with Macs
