Detachable 3D Earmuffs and Eye Mask with Light Breathable for Sleeping and Hearing Sensitivity Eye Mask 2 Pairs of 2-in-1 Blocking, Earmuffs,

---------------------------------------------------------------------- Note: To avoid discomfort from prolonged wear, do not tighten too much. The headband is made of soft, flexible polyester fabric, which is durable, resistant to deformation, and has a smooth, comfortable feel. The size can be adjusted with Velcro. The silicone headband has a non-slip design on the forehead to prevent the headband from slipping down onto your eyes. The eye mask's 3D contoured design effectively blocks light while preventing pressure on the eyes and allowing natural eye movement during sleep. For enhanced sound insulation, we recommend using it with foam earplugs. It also comes with a convenient storage bag to prevent fine residue from building up on the ear cups. The ear cushions that come into direct contact with the skin are available in two types: sponge and silicone. The sponge ear cushions are the same as those found in regular earmuffs, but the silicone ear cushions are more comfortable. Our earmuffs have air holes that balance the air pressure and prevent damage to the eardrum caused by air pressure generated when wearing the earmuffs. At the same time, these air holes also provide a slight ventilation effect to prevent your ears from getting stuffy. These earmuffs are designed with a double-layered, high-density acoustic foam that effectively reduces low-frequency noise, but cannot completely block out other noises, including: air conditioners, electric fans, keyboards, the TV in the living room, voices, neighbors, and noises and footsteps from upstairs and downstairs. They can also block out nearby cats, dogs, birds, and other animals. They can also block road traffic, highway noise, construction noise, and snoring. Our earmuffs are less comfortable when sleeping on your side, but using them with a very soft pillow provides a limited improvement. Because the human ear is particularly sensitive to human voices, most noise-canceling headphones do not provide significant noise reduction for human voices. People speak at about 40-60 decibels for normal conversation, and 60-90 decibels for in-depth discussions. Noises above 40 decibels disrupt restful sleep, while noises above 60 decibels cause more noticeable disturbances. 2-in-1 Detachable 3D Eye Mask with Light Blocking and Breathable Earmuffs, Soundproof, Lightweight, for Sleeping and Hearing Sensitivity
