2024 New Type Earplugs for Sleeping with Acoustic Filter Device, High Performance -50dB Noise Reduction, Sponge Material, 5s Rebound, Snoring Block, Hearing Protection, Airplane, Study, Travel, Work, Washable, with Case (Black) #Noise Cancelling Earplugs ◆【Doesn't hurt your ears even after wearing for a long time】Adopts a ring-shaped human ear engineering design, perfectly fits the ears, and uses skin-friendly polyurethane material, which is soft to the touch and highly elastic. Before inserting into the ear canal, the ear tip can be kneaded to any size. After inserting into the ear canal, the ear tip rebounds within 5 seconds, and is very soft and comfortable. Even if worn for a long time, or however you sleep, you can comfortably achieve noise reduction. 【Powerful Noise Reduction and Fashionable Appearance】Conventional noise-canceling earplugs have not actually been able to achieve a noise reduction effect. This time, we have added an acoustic filter device. This is a filter used to process acoustic signals, which can remove unwanted frequency components in the signal channel while retaining the necessary frequency components. This effectively achieves a noise reduction effect, reducing noise levels by up to 50dB. 【Freely Adjustable Ear Tip Size】Although various sizes of ear tips are included in the market, it is difficult to find the size that fits your own ear canal. Our ear tips use soft polyurethane sponge, and before inserting into the ear canal, you can freely knead them until they fit the size of your ear canal. When the soft ear tip is inserted into the ear canal, it rebounds after 5 seconds and fills the ear canal, ensuring a secure fit and enhancing the noise reduction effect. This is very practical. 【Multi-purpose】: In daily life, it effectively reduces surrounding snoring, keyboard sounds, noise, whistles, decorative sounds, etc., making you feel like you are in your own independent world without any interference. It also speeds up sleep. When working in a special environment, wearing our earplugs can effectively protect your ears and avoid stimulation from loud sounds that may damage your hearing. 【Package Contents & Washable】1 pair of earplugs, 1 storage case, 4 replacement ear tips. In the case of our earplugs, if they get dirty during use, you can remove the ear caps directly and wash them with water, then dry them with a paper towel. 18-18-310891
