X-Pro Earplugs are a great option for hearing protection on-the-go. Once the earplugs are comfortably settled in your ear, you can choose your hearing protection setting with the push of a button. The closed valve will protect your hearing by giving you 29 dB SNR with the black foam tips, or 19 dB SNR with silicone tips. When you need to hear again, instead of completely removing the earplugs, simply press the button again to open the acoustic valve, allowing sound to pass through naturally.With a click of a button, you can open or close the valve to choose your hearing protection. 19DB SNR Open 29DB SNR Closed
