Flip to Listen are the first dual-mode earplugs that not only protect wearers from noise but, with a quick Flip, also allow better communication when needed, without the inconvenience of removing earplugs. The Flip cap allows you to easily switch from a closed position (NRR 24dB), for protection from continuous noise, to an open position (NRR 4dB) when you need to communicate or hear.
