Review on 🔌 innoGadgets 10x Anti Dust Plugs for Smartphones, MacBook, Laptops, USB-C Dust Plug for Samsung Galaxy S8, S9, S10, Silicone Dust Plug – Black by Darth Naubert

They are dark gray or black. There is no aluminum cap to fall off. The color bleeds through all stoppers, unlike white plastic stoppers with a dark cap that falls off easily leaving the white plastic visible. My phone is Samsung S21+. In dark gray with dark gray body. These silicone plugs snap easily and will not fall out. They fit the phone without interfering with the case and the color blends with it so it's not visible at all. It doesn't protrude beyond the edge of the case, so the phone still sits perfectly on its vertical charging dock. My phone doesn't have a headphone jack so I can't comment on these plugs but for the price of 10 USB plugs I'm very satisfied. I'm sure the silicone material will improve the water resistance of the USB port. A few years ago I fell into a river with my Samsung S8+ and since then the USB port hasn't been the same. If I had one of these plugs, I'm sure things would be a lot better.
