Mixx adaptive earplugs are perfect for anyone who needs versatile hearing protection for various situations, such as traveling, events, music festivals, and concerts, or when you need quiet to concentrate. With three adjustable protection levels, you can easily adjust the sound isolation with a simple twist. The earplugs are made from hypoallergenic medical silicone, making them gentle on the skin and comfortable to wear for extended periods. The flange tips conform to the natural shape of your ear and are available in small, medium, and large sizes for optimal comfort. The three protection levels include: Travel, which reduces ambient noise by 15 dB; Music, which lowers the sound level by 23 dB while maintaining sound quality; and Study, which offers a reduction of 27 dB for a focused environment.
