ZOZZGO focuses on sleep noise reduction ear cups. Continuous efforts are only for the comfortable noise reduction of our users. ▶Question: Does it have a sound insulation effect? ▶Answer: Yes. We have measured that it effectively reduces noise by 26 - 30 decibels. If you need to enhance it, you can wear earplugs inside. When wearing it, you can hardly hear the keyboard sounds, the sounds of fans and air conditioners, the sounds of watching videos two meters away, the sounds of conversations outside upstairs and downstairs, and the square dance sounds a hundred meters away. The sounds that are efficiently reduced include the crowing and barking of chickens and dogs outside the door, snoring sounds, and the sounds of horns on the roadside. ✔Main uses: Sleeping, Studying, Working, Sound insulation and noise reduction ✔Material: ABS, Sound-absorbing sponge, PU, Silicone (for silicone model), Nylon (for elastic band). All are environmentally friendly materials and skin-friendly materials. The entire product achieves pure physical noise reduction and does not contain harmful components and metals. ✔Suggestion: By using closed noise-canceling earplugs + full-ear physical method, human voices can be isolated more effectively. ✔Special attention: For comfortable noise reduction, we have adopted an elastic band for wearing (the tightness can be adjusted and it is not easy to fall off when sleeping) and made the volume of the ear cups smaller. It is indeed slightly less effective in noise reduction than the large-sized noise insulation ear cups on the market. If you mind, please do not place an order.
