About Mpow Super Soft Sleeping Earplugs 60 Pairs With A

What Makes a Good Ear Plug? 1. Easy to insert and remove. If the foam plug expands so quickly, you would have no time to squeeze them into ear canal. 45s can be a suitable expanding time. 2. Comfortable fit. It depends on the plug’s size and material. Large earplug may cause pressure to ear canal, if so, try a smaller one. Breathable foam earplugs often cause less hurt than silicone earplugs. 3. Good Noise Reduction. Plug’s noise reduction rating (NRR) shows their noise blocking performance. Higher ratings (like NRR 32dB) are generally better. Mpow ear plugs meets all fine qualities above! NRR 32dB High Noise Reduction Rating Disco/KTV: ≥90dB, damage to the hearing.
