|E-A-R Express Pod Plugs are extremely quick to use, clean, and hygienic. Half slow-recovery foam, half easy-insert stem, Express Pod Plugs seat well and stay in place to provide an NRR of 25dB. Note: Sold in convenient reusable pillow packs, Express plugs are available in corded and uncorded versions, in a random assortment of stem colors including red, yellow, green, blue, and purple. No-Roll plugs feature a central stem that lets you simply push the plugs into your ears with no need to roll the foam before insertion. As a result, these plugs are simple and easy to use, and more hygienic because you never have to touch the foam with your fingers.
